i posted on reef central but did not get much help with the problem but they tried so if you guys might have some insight please help!!! here is a pic at the bottom that is about 4 months and at the top that is what happend at about six months
the sand bed was hit with a powerhead right there but it was green before i did that and no there is not direct sun on the tank.
Thanks for the fog light thing my buddy has been calling it the fog.
All levels are at zero nitrate, nitrite, ammonia, and phosphates so tell me that plus when i took some water out and add just bleach to that water the green did not go away so i am lost
SO ARE THE FISH IN THERE
i have a RO/DI that i use and i do not mix the top off water with salt and if i do it is very little I feed once a day and it is not very much food at that in conparisant to what i have seen some other people feed i also have a 29 gal tank that sees about the same amount of food and the phosphates in that tank are at 0.6mg/l
Well I guess the first thing I would do is probably a 30 - 50 percent water change, and keep doing them until it clears up. So is your skimmer pulling any of this stuff out? Are all your fish accounted for? My skimmer would be overflowing with gunk if my tank was like yours. Hang in there things will work out...
I remember someone elses tank having that problem. It was clear, then it was green, and later it cleared on it's own. It almost looks a huge phytoplankton storm. One thing you may want to do, if you can or have the desire.. take a sample of water to someone that has a pretty good microscope. I would look to see if the green is alive..if it moves, I would guess phytoplankton...if not, then algae. Just a small idea.
Wow... I'll never feel bad about the algae growth in my tank again... that's just insane...
I saw over at the Brand 'X' boards (reefcentral) where somebody's daughter had put sugar in his sump, and even that didn't look as bad as your problem...
I'm clueless though as to what the cause may be... wishing you luck on figuring it out.
I agree with karsco just keep on the water changes and do them often and hopefully it will work itself out. I had a diatom bloom that was almost that bad and I had to just do water changes every two weeks and eventually they subsided.
