I am hoping someone out there can help me.
I have a FOWLR 40 gallon tank with two Yellowtail Blue Damsel, one Sebae Clownfish and one Bicolor Angelfish. I don't know the exact levels of Nitrite, Nitrate, PH, ALK, Calcium, Phosphate, ECT.. but the LFS tells me there ok. The tank has been up for about 10 months and I have lost no livestock to date.
The problem I am having is green algae blooms, I have changed nothing in the tank and can't figure out why I am having this algae problem now. I do biweekly water changes (about 25%), the temp is a fairly consistent 78 degrees and the lights are on timers set for six hours white and 8 hours blue (Power Compact fluorescents).
I have been reading allot about UV sterilizers and how they can kill algae and bacteria. The question I have is wonít it kill the good algae and bacteria as well?
I have searched the threads on this and many other sites and everyone that uses UV sterilizers seems to swear by them but I canít seem to find any information on what may happen to the good bacteria.
Thanks in advance for any and all info!!!
