I dissolved a 250mg pill in tank water and then dosed it at night with skimmer off and no carbon. Did 3 doses over 6 days for BJD breakout.I think I’m going to do a icp test and use cipro. What rate or how did you go about using cipro? I’ve had this one frogspawn that’s melting for close to a year so I don’t think it would be lighting or flow.
I would get an ICP before cipro. You might be low on trace like iodine or something. I got my first ICP at 9 months and was amazed at things that were high and low.
