We recently did a full pond clean as part of a serious upgrade to the filters and fitting a retro-BD.
Everything is looking good but we noticed some flashing and found we have skin flukes (100% confident from scrapes - they don't have the 4 'eye dots')
We did a treatment at 1g/89gallon dissolved in acetone as per the book.
However two weeks later a scrape showed we still had them (no behaviour issues - just very occasional flashing from one or two fish)
We retreated and a week later a scrape showed them still there so we've re-treated a 3rd time at 2g/89g.
Each time we've turned off the UV and bypassed the drum and bios for 48h (not sure if this is needed?)
So now, 48h after the 3rd treatment a scrape on a goldfish showed 8-10 in a decent sample on one slide.
I got a tiny sample from under the gill on another goldfish and it had 2 skin flukes.
Nothing else visible.
So, first question:
When I 'dissolve' the Flubenol in acetone it actually appears more like a suspension. Is this OK?
I realise this could be the filler and the medication is dissolving just fine but I wanted to check.
Could they be resistant to the active ingredient?
Then the real one... what do I do now?
