It looks like I have some sort of new pink sponge in my tank with a few large entries ways, and other small vents.  There is a ton of activity that might be pods, but some of the "pods", seem to look like small fish fry.  Has anyone seen anything like this? 

I have a 5 stage RODI system that appears to be going too slow. It has a 75 gpd membrane on it.  Here's the stats:1)from the wall: 90 gph2)After sediment and 2 carbon filters at 1 micron it's running at 60 gph into the RO membrane with 46 psi.3) After the membrane it's coming out at 12 gph with...

Has anyone experienced an ASV causing about 200+ TDS to be added to the RO membrane TDS out reading before DI?  I went piece by piece on my RO system, and when I bypass the in only of the ASV, my mysterious 250 TDS coming out of my membrane drops to 8, put it back on up to around 250...

Can someone recommend some sand cleaners for a reef tank? I would like something hardy, cheap, lives more than a year or two, and can deal with some red cyno build up on sand or patches of brown algae. Also it's a reef tank, with inverts, and plenty of live rock so the creature(s) would need...

when the xenia heads/hands become nubs, and lots of nubs, does that mean a fish is eating them, or is that an issue with water quality?

This is the sump i have. Instead of bioballs I put in live rock that gets water trickled over it. http://dealofday.com/wp-content/thumbnails/112324.jpg In the middle chamber I have my external reef octopus sump return that creates a descent amount of flow back towards the waterfall plus air...

The seachem bag on the outlet on my purigen cannister came off spilling a descent amount of purigen in the tank. Is that a big deal? Will the purigen eventually settle in the sand and just become part of the live sand? What will happen? Thanks!!!

Is there a way to quiet a reef octopus external skimmer. It has a little clear plastic tall petri cup where the air comes appears to be sucked in. Perhaps it's the nature of the beast that it will be making a sucking noise, straw slurping noise. Or maybe there is a clever way to quiet it...

Reef breeders, Reef Radiance, Evergrow, mars aqua, different names - basically the same fixture. Would like to hear your experiences since these lights have been out going on 4 years now? Mine lasted about 1 year and then died. Has any of yours lasted longer, how long? When mine died I tried...

Does anyone have a dehumidifier i could borrow for like a week? Doesn't matter how old as long as it works. My ac unit line split and put water all down my walls and under my flooring. Thanks!!!

Guys, I have had purgien for a year, but probably never full understood it. I tried to get it flowing like jelly fish in a cannister and could never get the flow right without loosing grains out the out tube. Also when I put it in a bag and just dump it in my sump, doesn't the water just go...

Guys, I have Red Algae blooming in the tank for about 2 weeks now. I'm trying to stir up the sand daily, keep flow on it, and this weekend I'll turn off the lights. I'm also dosing No3/ph4 daily 8ml to bring down the phosphates and nitrates. Nitrates were testing at 10ppm, but that is with...

I have a leaking bulkhead between outlet and acrylic sheet. Previously a lot of silicon glue, i think, held it, but now it's pealing off where it's leaking. Should I just apply more silicon glue to where it is leaking and hope that holds it. Any ideas? Thank you!!!

Do you all have a recommendation on where to get these bulbs? I run mostly xenia, kenya trees, mushrooms, hammers, and toadstools. Nothing too exciting. In the past I stocked up on petcos clearance $8 zoo med bulbs. But now they are all out. ATIs would not be out of the question if that is...

On my 200 gallon the corner chipped off in the shape of a prism. [Like a piece of a triforce :)]. I don't really know how long it's been chipped off. It appears to not compromise the tank holding water. Should I consider filling in the chipped glass piece with something to prevent future...

Does anyone have an external skimmer I could borrow? My reef octopus didn't make the move from Richardson to Allen. Idiot me drop it and crack part of the acrylic. It was rated up for a 100 gallon tank. My tank is 56 gallon. I have put a bunch of carbon in the sump in bags. Is there...

I have been running a 72 inch dual T5 fixture for 3 years. Thinking about upgrading to LED. Any recommendations for a long cichlid light? No plants, or any need for really strong lights, just enough light to illuminate the tank and the make fishes colors shine for the price point. Thanks!!!
