I have a 90 gallon tank with a marineland 350, 200, and 150 with two powerheads and a skimmer. I noticed it getting cloudy and green about a week ago, so I changed out 25 gallons yesterday with the hopes of it getting better, but it didnt. I have about 50 pounds of live rock and 125 pounds of live sand. I have a 24 inch coral sun light on one side and a 24 inch coral life (65 watt) on the other side. What could be causing the cloudiness and green water?? Please help

This a new tank? What fish? Wat are your water stats? Don't forget your phospate readings. Temp of tank? How offen do you do water changes?

Along with the above questions...
Is it near a window?
Do you have caulerpa? (a type of macro algae)

It is not near a window. The tank has been going for over a month with the filters, rock, sand and 50% of the water from an established tank. I have a purple tang, dogface puffer, 3 clowns, a sixline wrasse, and a half black angel. Temp is about 80, havent checked phosphates, only water change I did was the one yesterday

That's a lot of fish to have added to a new tank, (if I understand you correctly it's only been up 1 month) check your water parameters and see what they say, it may be causing the algae to bloom.

Sounds like a phyto bloom. What tends to cause it is an environment rish in nutrients and a nice light source. Changing water can actually cause the "culture" to thrive like you were harvesting it.
Peeps have different way of dealing with, but I like UV or a diatom filter.
Caulerpa going sexual has always been whiteish in my tanks. This is an example of what my tank when the caulerpa went south.

mine is worst than that, i cant even see the back wall. and its not a new tank, the only thing that is "new" is 45 gallons of water. Everything else came from a 125 gallon tank that had been running for over a year

UVs can be had for pretty cheap. Diatom filters are definately more. But maybe someone else will have a success story of getting rid of using a different method.

What filter media are you running? (would something like ROWAphos help? Or Chemi-pure? Or maybe a very fine filter sock?)

Do you use RO water? What are your water parameters and your phosphate levels?? Do you run filter carbon??

Until you know what it is for sure, I would drop an airline in there. If it's phyto that thick you'll be fine in the day but at night your pH may be inclined to drop as your CO2 climbs and your O2 drops.

I use regular tap water but i treat it before it goes in. Ill have to get a phosphate test kit to see what they are. Yes I def need some more live rock, gotta build up my funds first.

My tank got like that when it was new, I had a horrible algae bloom, it got to the point where you couldn't see anything in it. Nothing worked until I wrapped the tank from all light sources, completely wrapped it for 24 hours without peeping at all, When I took the wrapping off the tank was clear, I added rowaphos to my canister filter and the tank has been clear ever since. I did lose one fish probably because of a PH drop but nothing else worked,

Theres no such thing as treatment for saltwater(nothing that actually works anyway). That stuff is for fresh water. You need an ro/di unit to treat tap water for a saltwater tank.
