Ich --surprisingly Fast Hypo Cure
The day before yesterday I discovered my 60l temperate tank had ich. One of my little common toadfish was covered, and a couple of ringscale threefins were also spotty. So I consulted Dr Google and the consensus seemed to be that hyposalinity was the way to go -- 3 or 4 weeks at 1.009.
So I pulls out my trustry hydrometer (brewing is such a handy pre-hobby for fishkeeping) and discovered to my mild horror the sg was 1.030. Four 6l buckets out and four 6l buckets of fresh in over the last two days and I've got the sg down tgo about 1.019 and guess what -- all the nasty little spots are gone. I'll get the sg down somewhat more and keep it there for 3 weeks, but it looks as though going down to a particular sg is not what kills the ich, but enough relative reduction in sg.
