I dispense full balling in the form of dissolved CaCl, NaOH powders and NaCl-free salt from Preis. However, I noticed that when using salt without NaCl, a brown deposit appears on the sand, and when I stop using it, it visibly disappears. Will stopping dosing permanently disturb the ionic balance that so many people talk about and observe, which may lead to the destruction of the tank? I will also add that I also dose TM A- and K+ elements, and I also do constant water changes every week in the amount of about 8% with TM Pro Reef salt. I don't use Balling in large amounts yet, +-20ml/day. The main cast are LPS corals. Everything is growing nicely, but I have been breeding for 14 months and populating the aquarium with small strains, so they are not large colonies yet.
