I have a 10 gallon planted tank which has gotten so green everywhere i can hardly keep up! The water is clean and tests fine. I have no fish at the moment and I use Leaf Zone for the fert. It's sand-not gravel. The plants i have are java fern, anubias, and a small type of crypt. 'm thinking of going back to plastic plants because my tank is a mess and I've kept everything as clean as I can and even lowered the hours of light to 1-2 hrs. Help please?!
