To date, KSh 7.4. Calcium 480. Magnesium 1420. Nitrate about 5. Phosphate 0.06. In terms of nutrients (import / export), the balance has been caught and at this time the system relies only on the skimmer and the compartment with live stones. Microelements K+ and A- from TM and FlatwormStop and Coral Booster from KZ are added. Commercial bacterial preparations are not added, carbon additives are not added, there is no coal, there is no mechanical filtration. Feeding fish four times a day with a mixture of pellets from AF, ON, hikari. Additionally, a day later, algae from AF and Artemia when I am on site. I don’t feed corals, maybe I’ll try Bauerbanks, as I need to test the new food for LPS from Af, but I’m not in a hurry, because the banks feel great like all the other LPS and Acropora. No loss
