Hi all,
I have a 60 gal
frag tank, plumbed in to my main system, all together around 350 gal or so. The
frag tank has multiple powerheads and has a lot of flow, and 12
T5's split between 10K's and
Actinics. About 3 or 4 weeks ago, it developed a bloom that resembles the
diatom bloom noted in new tank set-ups. In new tanks the bloom goes away in a week or so, but this is just getting worse. I added a bunch of snails which are helping a bit, albeit slowly, and the areas that the snails clean quickly become covered with
diatoms again. Any insight on what might be happening here? Of note, my
refugium has a
cyano outbreak, on the top of its
DSB. The 210 gal disply has no problems that I can see. All measurable parameters are fine. In the display, all inhabitants are thriving, including SPS's, LPS's and fish.
Thanks as usual,
Jay
