How long has this tank been up and running? what size tank do you have and what filtration do you use, liverock,
DSB,
fuge,
sump,
skimmer etc? did you make any other changes except adding the new lights? what stocking levels do you have in your tank? what methods to control the algae have you tried so far? sorry for the list of questions ...
If
No3/Po4 are the problem you could try performing some water changes - ensure any make up water is using
ro/di/distilled and not tap-water. You may not notice an immediate decrease in their levels, depending upon what levels exist in your tank, substrate etc - however, over time, the levels should come down unless you are over feeding and overloading your filtration. You may also want to reduce your
photoperiod, reducing the amount of light available for the troublesome algae. If you are manually removing the bubble algae try not to burst them as you remove them. If you are manually pulling up some of the hair algae but be careful not to let small pieces drift around inside your tank as they will tend to settle and take hold elsewhere.
Battling hair algae is a common problem, there is a good recent thread here "
need hair algae ideas" were Astrivian has been battling a recent outbreak of hair algae!
