my tank has only been set up sense Dec. 1 . I went through the diatoms and green algae. Now it seems as if i'm having another diatom. my parameters are ammonia 0, nitrites 0, nitrates between 5-10, phosphates 0. I cycled with live rock, I'm running GFO, I have 2 10k and 2 actinic t5 bulbs. my only change is im running my lights 12 hours rather than 8. What is causing this?????
