<h3 class="first">MY ALGAE SCRUBBER PROTOTYPE</h3>? alt="Post" width="11" height="9" />by DFW on Wed Feb 15, 2012 1:11 pm?I have experimented for a number of months with a 1 sided algae scrubber, and through that have developed a liking for this technology! I like it enough that I decided to run one in place of my skimmer. This is very crude in construction, but I think that maybe it could be used as a jumping off point for a very simple scrubber that is easy to maintain, and keeps all the water where it should be, in the sump. I still need to refine the sheeting of the water on the growing surface, as some is squirting outward on one end rather than flowing downward. The top and the right side of the acrylic box are removable as one piece to provide access for removing the growing surface/plumbing for routine cleaning. I am including a couple of pictures now, and will offer others later.Thanks for looking!David<dl class="file"><dt> alt="algae scrubber left.JPG" /></dt><dd>algae scrubber left.JPG (78.47 KiB) Viewed 6253 times</dd></dl><dl class="file"><dt> alt="algae scrubber right.JPG" /></dt><dd>algae scrubber right.JPG (59.14 KiB) Viewed 6253 times</dd></dl>?- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank?<dl id="profile711300" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

I made small acrylic holders that fit the reflectors. The reflector on the right is 8 1/2 inches, and the reflector on the left is 10 1/2 inches. I am using 2700K 23 watt curly fluorescent bulbs at this time. If I were to hinge it, I don't think it would help. There is no room to swing anything anyway. The way that I have it now, I merely lift up the right side, which is hooked/hanging on at the top of the left half, and set it down out of the way. I did not want to have to lift the screen assembly out of the top when cleaning because water would drip on everything. This allows me to simply take the side off, and come right out the side with what needs regular cleaning.Thanks for the input!David- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank<dl id="profile711329" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

I ran one for a while but I really just don't have the fish needed to support one, be sure to change those bulbs every few months. As far as LEDs they aren't really much better for ATS IMO, plus they don't like humidity. Oh and the first time you clean it use a toothbrush and try to smear the algae over the entire growing surface, which I assume you scruffed up.

It has not had perfect sheeting of the water over the surface of the screen during most of that time. And water has tended to flow more on parts of the screen than others. And water has squirted outward, rather than flow down the screen in other places. I have tried several things to iron out these problems. A simple piece of felt material around the top of the pipe and fastened to each side seems like it might solve all these issues. We will see!

Here are some from today. The 10 1/2 inch reflector works better than the 8 1/2 inch. The 8 1/2 inch has the bulb too close to the acrylic, and doesn't spread the light as well as the larger one. There is still a lot of brown algae, but the green is spreading. Anyway, it's all hanging on to the screen, exporting nutrients when I wash it in the sink. I think that with my system it will only need one side cleaned every other week, or so.

And I removed about 20 pounds of live rock from the system a few weeks ago as well, and started adding phyto most every day, too. I had a light green acro start bleaching about a week ago, and it's turning brown now, after having turned white. I had placed it right at the top of the rock, and was too close to the light, I think. And I am seeing today that a very fast growing acro with a light green base upwards to sky blue tips of new growth is lightening up to a tan color on the branches, although it is retaining the blue tips, and green at the base, and green polyps on the tan stalks. It is fairly high in the tank. too. I understand that many of these corals are brown in the ocean, and that in our tanks, we get colors not always seen in the wild. I understand, also, that corals will change colors during certain events, and then return to their "prettier" state when we provide them with the right conditions. I am hoping, and trusting, that is the case here! I do not think that switching from a "cheap" skimmer to an algae scrubber has anything to do with this! I am more inclined to think that a somewhat sudden reduction in alkalinity may have something to do with it. I had been adding more baked baking soda each day than I should have for several weeks. Upon realizing that, 3 days ago I stopped doing that, and just added the daily limewater dosing, so the alk has fallen back slightly from around 9.7 to 8.7 over 3 or 4 days. I am now increasing, slightly, the daily dose of limewater so as to elevate the alk back to where it had been, and this will achieve the proper calcium level as well.I have not tested for phosphates, but since nitrates are at 0, and since I believe that an algae scrubber deals with phosphates as well as it does nitrates, I don't think that phosphates are likely to be a contributing factor to any of this either.Any insights will certainly be appreciated though!I am scraping a good bit of algae from one side of the screen every week.Thanks for your interest!David- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank<dl id="profile728787" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

Well, for 70 days now, at least, with God's help, I have been. I have seen no increase in any "bad" algae. There are still no nitrates. There are no bad smells - I expected that without skimming that the water might stink a bit, but not so. During this 70 days I removed at least 20 pounds of live rock, and have fed phyto 30 days, which I had not done while using the skimmer, so actually have put more "pressure" on the scrubber than was on the skimmer, but everything looks to be ok so far. I am still running carbon for 12 hours each week as I had been all along. I am scraping 1 side of the screen each week now and getting several cups of algae from a scraped side. It is sticking fast to the screen - I keep some polyfill quilt stuffing under the scrubber to dampen what would be a splashing sound if it weren't there, and little debris is deposited there by the scrubber. I disconnect a hose fitting from the Mag 5, set the 2 lamps to the side, and carry the whole scrubber unit to the kitchen sink. A scrape, and a rinse, and brush run through, and around the feed pipe, and a good rinse of the felt that I use to eliminate water squirting other than on the screen, re attach the felt, and it's back in business! (The felt actually is preventing algae from growing into the slot of the feed pipe anyway, and I am using a foam filter on the Mag 5, so not feeding debris in there anyway.)Thanks for looking!David- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank<dl id="profile730532" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

Thanks!I am hoping that this is the very simple answer to eliminating many problems that are had in this hobby! If it basically removes everything that you don't want in your tank except silicates, and you want some silicates in your tank, while allowing the reef plankton type things to pass right on through to be used by the reef inhabitants, it seems to be a win win situation to me. Will sps coral do well in a system without a skimmer, and all the other gadgets being used by most today? I am hoping so!I dose lime water, and run this scrubber. That's basically all that I do, except do a 5 or 10 gallon water change every other week in a system that holds 120 actual gallons of water, and run 1 1/2 cups of carbon for 12 hours once a week in a Aquaclear 70. I am not saying that this is "it".

I have tested my water for phosphates just now for the first time in the almost 4 years the tank has been running. It shows to be 0 ppm - a very pale, clear yellow. I am sure that this is not considered to be the most accurate test kit for phosphates, but since the next color on the chart is green, and 0.25 ppm, surely I can at least gather that it is much closer to 0 ppm than it is to 0.25, since there is hardly any yellow color, and no green. And the kit is marked with an expiration date of Jan. 2015, so, I expect that it is a fresh kit.I have heard that you should rinse all of your frozen food before feeding to eliminate phosphates. I never have done that. I feed it 2 or 3 times a week soaked in Reef Plus, and I dump it all in. I have heard that flake food often has phosphates. I feed spirulina flakes 3 or 4 times per week. I sometimes feed pellet food once per week. I feed a tiny particle sized food once, or twice a week, too. And I have heard that feeding anemones can cause problems with all of their waste products. I have 20, and feed each one 2 or 3 eraser sized pieces of silversides, or more if they will take it, 3 times per week. I rarely find any waste products from the anemones that needs to be removed from the tank either.David- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank<dl id="profile731065" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

JK JK... but that is crazy looking. I ran mine for months and it never looked like that. The only time I had to clean it was when the algae started to hang off the screen on the bottom. But it never looked that thick. I also only ran one 60W bulb for 16 hours a day. Never read that you should do it that way but I never wound up cranking it up to the advised light settings.<dl id="profile731100" class="postprofile"><dt> alt="User avatar" width="96" height="78" /></dt><dd>Premium

I don't think so! And she is not a virgin any more any way. She had a number of children by Joseph after she bore our Savior by the Spirit of God!I don't know what the "advised light settings" are. I guess that you could use any wattage bulb that you want.

Acrylic is put together with acrylic solvent cement. I made the 2 piece box so that it would fit inside the sump tank. I made it so that it would be as far into the sump as possible without getting the reflectors wet when the power goes off and sends more water down there. And I made it as tall as I could make it and still be able to take it in and out easily without getting in a bind anywhere. The box is 3 inches wide, although I am thinking 4 inches would be ok, and maybe better. The 2 narrow sides, the bottom, and the left side - looking at my photos - where the water line comes in through a cutout on top, are one piece. The top, and the right side are one piece. You just fix it where you can set the right side in to the left side.I hope that's at least a little clearer than mud!David- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank<dl id="profile732988" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

All the corals look good to me. Well, at least the ones that were looking good still look good to me. It seems like I am having to clean the glass a little less often. I have increased lime water dosing during this time as well. Rather than dosing 1 gallon saturated solution every night, and adding baking soda, too, I increased to between 1.25 & 1.375 gallons saturated solution, and no baking soda. I will likely change the light bulbs soon, since many have said that they should be changed every few months. I am presently using a piece of felt draped over the top of the scrubber with a large loose fitting rubber band keeping the felt somewhat snug up to the growing surface. It is working ok, but am still thinking there is a better way. And I am wondering if a Mag 7 pump would be better than this Mag 5. Sometimes it looks like it could use a little more flow.Thanks for looking!David- 65g acro tank w/DSB, 2/3 plenum, 4 39w T5s, 30 royal blue LEDs- 26g sump w/Mag 5 algae scrubber & Mag 3 return - Inline - 18g shallow frag tank, 29g acro tank, 8g cryptic- 29g divided quarantine/rose bubble tank<dl id="profile744467" class="postprofile"><dt> alt="User avatar" width="57" height="43" /></dt><dd>Premium

I am still running this scrubber. I have found that you get better water flow by having the screen hanging just below the slot rather than having it inserted in the slot. It gets much better flow this way.
 
It grows algae. Only the modification that I mentioned in the previous post has been made, and it makes a big difference on the flow. I also have placed a sponge filter on the inlet of the mag 5 pump that runs the scrubber.
 
I have a small skimmer rated for 30 gallons on the frag tank that is inline with this system. It seems to help keep that small frag tank cleaner than without it.
 
Wow that is great, ever since I saw this I have been thinking about a design for my system. Thanks for sharing!
