I have an ich outbreak on my non-corys. I caught it early. I have snails and a preference (but not unbreakable stance) against meds. I would prefer to attack this with heat and/or salt, if viable. I've gradually raised the temp to 84 degrees and gradually salted the water to 1 tbsp/5 gallons over 36 hours via a series of small changes. A few spots remain, but if anything, it's better. Nobody is flashing. The corys seem a little less active, but I'd still call them very playful and hungry. I see 86 degrees and 2 tsp salt / gallon commonly mentioned as an effective ich treatment, but I know that both would be particularly hard on the corys. Do I dare go hotter and/or saltier, or is this a good compromise?
