I recently swapped out my t5 for a d120 led (I removed all the optics for better coverage) on my 29G anemone tank. After a few days I noticed bubbles trapped on LR rocks and back of tank. Then within the next few days everything started to get ugly! algae films that appears to be either dino...(I can't spell the rest) or calothrix. I should have snap a few pics for better ID. Anyway, I went ahead and reduced intensity on the LED as well as light cycle; H2O changed (15%); light-out for 36 hours. Today, all the algae appears to starved out. clean PH and return pump and increase return pump output a bit. Also, get ready for another 15% WC.
I hope this will be enough to get rid of those algae. I read that some people had to take down their tank to treat dino.
Just wonder how can a light upgrade can cause such outbreak?
So far my 2 GBTA are pissed off and moved around. They has rarely moved since I placed them in there.
RBTA did not move, fish don't seem to mind. Snails, however seem unhappy!
