I have a large 250 gallon reef tank and for some reason have a hard time keeping BUBBLE CORAL up and running. They look good for a few weeks and then 'slowly' start to fold up. My tank is near perfect. ALL the parameters are near "0"...it gets 30 gallons of water changed weekly...temp. is...

I have a Chiller, Model SL-300A, and it will NOT cool down my aquarium water. It IS a large tank...250 gallons with 3, 250 watt, Metal Halide lamps. Obviously it does get hot under the vented (fan) hood. I set the Chiller to 76 degrees and it will NEVER get there... Yes, the room stays warm...

I have a 250 gallon reef tank and 1 of the hinges on the canopy broke in half. (there are 3). Does anyone know how I can get another OR does anyone have a number for Oceanic. I sent them an e-mail but who knows when I'll hear back. I thought they would have an 800 number, but I could not...

Anybody know the key in keeping one of these 'suckers' alive? I have a 250 gallon reef tank with 'near' perfect water parameters, but everytime I get one of these....a 'lobe' slowly but surely starts to die off...white skeleton! One lobe goes...then another...then the next...until the whole...

I have had 3, 250 10,000K Metal Halide Lights going for about 18 months now and was wondering if I should change them? When should you change your lights? Do you need to change them? Curious about the reasons why people change their lights after a year or two and really haven't understood...

I try to keep my Reef/Fish Tank at a salinity level of around 1.024. Is 1.025 bad or a little higher? I was just wondering where are the 'boundaries' your tank should range. It's bad if it's lower than ______ and it's also bad if it's higher than ________. Just curious what everyones...

The Bubble Coral is probably one of my favorite Corals and am presently looking for another large piece. Maybe the size of a softball or larger! Does anyone know of anyone locally that has one available? I've had a lot of luck with these and really like the additions in a tank. I have heard...

Shortly after ANOTHER 50 gallon water change in a 250 gallon reef/fish tank, the nitrates ONCE AGAIN read 20 ppm. (Actually, probably only about 150 gallons of water) A number that NEVER goes away. It will for a day or so go to 10-15ppm, but within 3 days back to 20. ANYWAY, so I bought...

Does anybody feed their Corals at night when the lights are off, or the 'moonlights' are on? Just curious to know. I've never done it and 'assumed' that feeding 'these creatures' should be when the lights are on.

I saw a LARGE Red Lobo yesterday and was thinking about buying it. This coral was in PERFECT condition and had to be 8-10" in diameter....to say the least, it was big! Show piece quality. Anyway, the asking price was $120. Is this a good deal? I thought so, but held off buying it. Again, a...

I have read some interesting success stories on these 'relatively new' sulphur denitrators. Does anyone have one and are you happy with it? They seem to work. No 'food' to add to keep the bacteria 'kicking' or anything else to do. Results appear to be very good out of Europe, but they are...

I make my own salt water and have a real nice 6-stage ro/di system hooked up. I took a TDS reading out of the water coming out earlier this evening and its reading 002. I know a 'new' filter will probably give you a 000 reading but I was wondering if 002 is still OK to make salt water? OR...

Does anyone know how the DWA, The Shed Aquarium, etc. get such large pieces of coral? Do they know 'special' people? Obviously, you can't get pieces this large at your LFS. I've always been curious about how they get such large, beautiful, specimens..... :?:

I have a large, 150 gallon, DAS aquarium that I am converting to a Salt Water Tank. First things first....I have a friend that HAS the tools (Diamond Saw...etc.) to cut the holes in the bottom of the tank for me that I need to run a refugium, sump, etc... The question I have is how BIG should...

I have a 150 gallon DAS tank which I am presently using for Cichlids. I already have a 250 gallon reef tank, BUT I want to convert this one to salt water. First....how do I take out the 'box' in the back left hand side of inside of the tank? Can this be taken out? This is the box that holds...

I will be making my own salt water soon and have purchased a 5 gallon bucket of Tropic Marin. But, I'll be damned if it does NOT tell you ANYWHERE on the bucket on how much to mix! I know this stuff is made in Germany, and I have used it for a long time (which I bought), but would like to know...

Just curious how many people make their own salt water. With my large tank, and with a small RO/DI system which I use for 'top off', I buy my own at 95 cents a gallon....Tropic Marin of course :lol: Does it get a little expensive buying this IF you change water frequently?....well, sort of...

It's on YouTube, but I have added a link to see it. I guess it's not bad for a guy that is still learning the hobby. Any comments would be appreciated. Sorry about the reflections...I still have NOT been able to figure out 'good' photography yet despite the threads I have read... Thanks...

I wrote a post about this a couple of weeks ago and thought I would follow up. I have a beautiful 250 gallon reef tank, water quality 'near' perfect and ALL the Corals and Fish are doing superb. I have struck out twice on Elegant Corals BUT thought I would give it another try. SO...........I...

How are you guys taking pictures of your tanks? In the world in me, I can not get a good picture. I have a Canon Exilim that takes great pictures BUT can not get one of the tank. With the flash, it's too bright and 'wild looking'. Without the flash, it's too dark! There's got to be a way to...
