Okay, now on week 3 w/ the cycle. I conducted a 20% WC approx 3 days ago and nitrates still at approx 20, nitrites 0, amonia 0 and ph approx 8.2-8.4 however i'm starting to notice alot of hair algae growth. Do you guys think i should have my metal halide on for approx 8-10hrs / day while cycling? I think it is promoting the algae groth. I plan on another 20% wc in the next few days. Thoughts????:confused:
 
It sounds like your tank is already cycled. I would continue with the PWCs. Are you using RO/DI water?
