Anyone have any experience or input switching between salts. I have gone between Reef crystals and regular instant ocean depending on price. I read that changing water parameters can couse trouble for fish and there is a difference between these two. I also used Red Sea that I got from a hobbyist. It was after that a fish of mine got a swim bladder issue. That salt is very advanced. I think the little bucket costs as much a big bucket of Instant Ocean. So water parameter were changing drastically. Anybody switch salts from time to time?
