My tank has very high calcium readings - around 850. I believe this is the result of my buffering the tank with Kent's Osmoprep (which contains calcium) without enough calcium-consuming organisms in the tank. I added the buffer because I can't seem to keep any snails alive and the alkalinity had seemed low. Now the alkalinity is fine (9), but the CA is high.
I want to bring the calcium down to a safe level without hurting anything. Do people think a 20% water change combined with a 2-week wait to let the cheato algae in my refugium work is the right approach?
The tank is a four month old 46G bowfront with a Remora Pro HOB skimmer, large HOB Aquafuge refugium, and Eheim 2026 running carbon. There are currently 4 fish in the tank: three fire fish fish and one starlight algae blemmy. All fish are doing fine. There is an emerald crab and a few small hermits. Ammonia, nitrites, and nitrates are nil. Salinity is .1024.
