Yea did the one scoop per ten gallons. UV/Carbon reactor off as wellLooks similar to what I had in my tank and Chemiclean got rid of it instantly. It was almost like magic. Did you dose the correct amount for your tank volume?
How long did you leave it in for?Yea did the one scoop per ten gallons. UV/Carbon reactor off as well
It didn’t die at all. I’ll even blow it off the rocks and it comes back. Nitrates 12 and Phosphates 0.10Did it die and come back or not die at all? It might be feeding off the detrius that are still on your rocks if it did intially die off
It’s been 72 hours and I still have the UV and Carbon reactor off.How long did you leave it in for?
Sounds good. I’ll try some manual removal and try againYes that’s Cyano, sometimes takes more than one treatment if the cyano is thick and matted. I’d suggest 20% water change and then repeat dose
Also, you may have thought of this already but I thought I’d mention, include your sump water volume in the calculations for the total volume to be dosed. For some systems this doesn’t make much difference, but for other ones this can alter the dose. Also just so you know, I’ve overdosed chemiclean into my display before at 2x the recommended dose. Didn’t cause any ill effects, on a mixed reef tank with softies, LPS, SPS and NPS. I would suggest to redose nitrifying bacteria when overdosing though.Sounds good. I’ll try some manual removal and try again
The pink clumps struck me as being very pink (could be lighting) and clumped and less translucent then I usually observe. This treatment might have been a partial kill or very disturbing.If you look closely, theres some color variation on the pictured cyano patches. Some are more red while other parts on the left are more brown.
The redder ones are more cyano dominated, the browner ones are probably more of a mix with dino/diatoms etc.
I have an air pump in the little tank and the skimmer overflowing in the big tank. So far so good… I’ll turn lights off thanks!Supplement oxygen with an air pump and lights out also.
Cyano are a photosynthetic bacteria. The antibiotics combined with the blackout should get rid of them.I have an air pump in the little tank and the skimmer overflowing in the big tank. So far so good… I’ll turn lights off thanks!
