I have gone through the search to try to find the answer, but sometimes there is too much to sift through. I have also looked through my SW
books before bothering with this question.
So here goes,
I have upgraded my lighting in my 75 gal SW
tank to 175W MH
lights. The tank had been doing great, now there has had a big, huge increase in brown/green algae on the glass. It is spots, not hair-like.
My tank has 2 true perc clowns, scotter blenny, cleaner shrimp, 4 peppermints, bunch of turbos & hermits. with 100 lbs of LR
and a 4" DSB
lights are on for 11 hrs, with the actinics 1 hr before and after. All the readings are normal; ph, alk
, amn, nitrate&nitrite, calcium.
Is this normal due to the increase in light, or do I need to address something else with the tank. How can I clear this up, I am cleaning the glass everyday now, rather then twice a week before the light change.
