They (4 3" Gold Nugget Plecos) will eventually be in my discus tank (hopefully), so I had been keeping them at a pH of ~ 6.8 and a temperature of 84. I bumped up the temp to 88 over the last 12 hours, and I have also moved my extra UV sterilizer into the tank.
I agree in trying the heat method, but I also wanted to get some feedback on medication in case I have one of those really nasty breeds of Ich that tollerate high temperature. My reason for concern is that I generally have not had issues with Ich at 84 degrees and these guys are new. Luckily I was good and I have them by themselves in a bare bottom quarantine tank (with wood). Having discus has forced good quarantine habbits.
My plan for now is 2x daily water changes to get as many cysts as possible over the next few days. I have a heated RO reservoir system so I can match the water parameters exactly. If the heat treatment is effective I should see a reduction in the spots over the next few days given the sped-up life cycle. If I don't see a reduction, then I may well need to attempt medication and I figured it might take a little while to get feedback from the forum. So I thought I would ask now so I can make an informed decision. I am also in the process of getting a 14" Gold Nugget Pleco, so the stakes are even higher once I have that one. So, the more knowledge I can acquire about what works and what doesn't the better.
The other side to using copper based products is its toxicity related to low pH. I have read that copper can be more toxic at lower pHs. Does anyone know how low is too low? If I have to medicate, I was thinking of going up to 7.0, but is that high enough?
Thanks again for the feedback!
