green water problem?

[BCOrchidGuy]

Rotifers would eat the green water, as would brine shrimp etc. Do you get sunlight at all hitting the aquarium? Light intensity from two normal fluorescents and two actinics shouldn't be an issue but quality of light may. Nutrients may also buy your nitrates should reflect that. Take a sample of your water into a local pet store and ask them to verify your tests, perhaps your test kit is out of date. What's your water source? Do you have phosphates in your water or iron?
