This is the first time getting ick, I attribute it to the other day my heater failed on in the evening and didn't get replaced until the morning my temp dropped maybe could have kicked started it, so I did a 60% water change yesterday and added API stress coat+, with aquarium salt 1 tbs for every 5 gall, and raised the temp to 88, but my questions are how often should I change the water?, and I should remove the gravel and soak in hot water? I removed all plants and decor. I have a 25 gal freshwater setup with four jack Dempseys under 1', also removed the carbon filters in my aqua-tech 30-60 filter. If I do get some Ick meds like Ick guard should I add that with the saltwater as well I don't want to stress the Lil guys out any advice would be appreciated.
