is it close to a window to that the direct sunlight can get to the tank all day?

No i havent upgraded my lights did that like 3 months ago Could this be the problem My water was getting cloudy so I thought that it might me the live rock so I took about 40lbs out and placed it in another tank that i have downstairs and there is only like 5 lbs in there Now that i think about the green water didnt show up until like 3 days after i took the rock out

no what causes green water is a single celled algae usually it only shows up in FW tanks though. do you have any fish in the tank?

there is only a few methods that can get rid of it permantly
1 change all the water in the tank * this will only work if the food source leaves with the water*
2 starve the algae with light deprevation * overing the tank with a heavy blanket for 4-10 days
3 a diatom filter to filter it out. maybe your LFS rents them youll have to check some do some dont.
4 a UV filter to kill it as it passes through
5 chemicals which I dont recomend some of them can damage the tank.

do you have any corals on those rocks? if not I would worry about them it wont be a big deal to the rocks being dark.
just dont peak for about 5 days though if you allow light to get to the tank it will rejuvinate the green algae growth to start up again. If you do this and it is gone and after you tank the blanket off you will need to drain all the water and start over becuase it isnt killing it off.

Hi
do you have sponges or filter floss in your canister. is your phosphates hi , that can cause green water UV light mite
help .I'd say your phosphates are hi and how old is your test
kit . i get algae on the side of the glass some time . thats
only when i use cheep lights , don't do that any more
check your phosphates and your TDS from your RO unit
add a DI unit . a DI will put you at 0 TDS
hope this helps
