Not sure what I am dealing with here I had a bad cyano problem about a month ago. I wasn't sure why I had the bloom, because I was getting good flow and wasn't overfeeding. I added a refugium and seemed to solve my problem, but then too much cyano was in my fuge, so I added a very lowl flowing powerhead. This could be where my new problem stems from as I have unplugged the powerhead because I wasn't seeing growth in my cheato.
I now have several small bubbles sticking to my rocks and some of my coral (pic 1). I also am starting see a "slimy" covering on the rocks and some zoas (pic 2) and lastly, I'm getting a dark brown algae on my DSB (pic 3).
Can anybody tell me if this is another cyano problem or new algae and if it is related to the bubbles or my refugium. I also recently upgraded my lights from PC to 4x54w T5. Appreciate any advice.
Important info:
Tank is 6-7 months new
ammonia 0
nitrite 0
nitrate 5ppm (dropped from ~20ppm through WC)
Alk 8 dKh, Calcium 420
