I just bought a 500 gallon acrylic tank. It's 8ft long, 3ft high and 3ft deep. I want to plant it for freshwater south american cichlids. I plan on using fluval stratum. What kind of lights will reach 3 feet deep? And I know I will have to do CO2, what setup do you think i will need? I have 12 tanks already, so I know how to take care of fish. But I am new to the planted world (except my 33 gallon long which gets all the light with my fluval sky). Please help, I need advice!
