^ Yup, like I asked in your other thread last night what were the test kits you had? In testing for possible causes for algea, check nitrates, phosphates, and silicates. You should also get some alk, ph, ca, and mag test kits too, along with a refractometer to measure your salinity. You'll have that water cleared up in no time once you pinpoint your source of the problem (water params, lights...). And if not, you can try to bribe LUNA into coming over to help!
