Fluconazole leaching from sand?

[CK00020]

I have a bryopsis problem and have been treating with reef flux or the flux rx, maybe 3 times in the last year. So I was just getting ready to dose again and was doing some tank maintenance, pulled some algae manually and vacuumed sand(I do this every month or so). It’s been a couple days and my bryopsis seems really receded, could I have stirred up some sand with flux in it, or released some that was leached into the sand. Any thoughts?

Maybe. Or maybe you've gotten enough of it such that it's having a hard time making any headway each time you perform maintenance.

Same issue.....

Doing my third treatment in the last year of reef flux for bryopsis.

Anecdotally, when I went away on vacation(was going to dose when I got home) for a week, got back, and 90% of the bryposis is gone. No idea where it went, or how it died, but it just did.

Fluconaxole will not likely stick to calcium carbonate surfaces, but it will likely bind to organic matter (detritus, tissue surfaces, etc).
