Has anyone had success with hyposalinity for ich treatment? I noticed a few white spots on one of my puffer's fins on Monday. On Tuesday I started to gradually add freshwater. I also raised the temp to 85 degrees. The puffer still only has 3 spots on his fin so the ich does not seem to have progressed. Is it safe to introduce freshwater on a daily basis? Or should I add some twice a day? I appreciate any advice. Thanks!
