I've had a group of fish in QT since early April. Some showed signs of velvet, so in went CopperSafe, to an API reading of about 1.75 ppm.
Four weeks in, and I performed a partial water change, as the tank has been persistently cloudy, with a yellow-green tint. Same as all the other water changes, but given the timing, I felt it safe (even prudent) not to replace the copper in the new water, and to dose Prazi-Pro, as I was again seeing some flashing and head-shaking. (Couldn't be velvet, right...? Nobody is showing any spots, no dusting . . .)
It wasn't long before the powderblue started flashing more vigorously, and swimming in the flow of the powerhead. (Tank is a 75 gallon, powered by two Aqua-Clear 110s [foam blocks only] and a venturi powerhead blowing bubbles and current across the back.) Bring the copper up again - this time to a solid 2+ ppm.
Everyone settled down a bit, everyone is back to eating aggressively, everything's good, except that the tank is still murky. Performed a 30+ gallon water change on Monday, replenishing CopperSafe as I went, which helped ... but only temporarily.
Not good enough. The regal angelfish, in particular, is rubbing her gills on the PVC, head-shaking and fin-flicking, even a week and a half back into copper. Her fins were looking ... off ... but not really anything I could nail down - until tonight. Pretty sure that she's got a nasty bacterial infection, especially at the base of her right pectoral. I'm not surprised, as there seems to be a persistent, nasty bacterial bloom throughout the tank.
I won't deny it - I'm in over my head again.
Video below, focusing on the angelfish. Unfortunately, she wouldn't show her right pectoral until near the end of the clip.
I've got some Erythromycin, some Furan-2 ... I think, some Kanaplex ... floating around. Time to rip open some packets? (And do I have enough to dose a 75? For how long ? . . . <goes to check>)
