Algae help please!!!

[sevitz5]

I’m battling what I believe to be Dino’s and other assorted algae......I don’t understand why. My tests I just did is, Ph 8.31, PO4 0.04, and NO3 10.

Here is some background, my tank is 6 months old, I combined 2 biocubes when I set this 110 up. I have a sump with chaeto (that died at the start of this outbreak), I dose Alk, Ca, acropower, and Nopox. I have a BRS reactor that I run a combo of gfo and carbon. I use all rodi water, and my lights are the AI Hydra 26, and the Aquatic Life T5 Hybrid. My LED’s schedule is 8am to 11pm with a 5 hour peak. The T5 only runs for 2 hours right now, as I was acclimating the tank to the lights.

At the start of this outbreak, my NO3 was zero.....so I turned off the Nopox, Acropower, and gfo.....I was told ultra low nutrients was the cause.

Anybody that has battled Dino’s and won, tell me how you did it.....I’m getting very frustrated. Thanks

Sorry to hear about your troubles. The experts here should be able to help. Until then, did you try going dark (no lights) for a few days to a few weeks? Watch the corals to make sure they can tolerate the lighting changes. Going black always seems to work for me when I have an algae outbreak. It looks like you may have red slime issues from the pictures. Less lighting/no lighting should help with that in the very least. Keep up with your water changes. Good luck!
