I have a 75 Gal. tank. although there is very little in the tank. I recently decided to add a coral banded shrimp and an emerald crab.
Before moving I ran a successful reef for 5 years. Now in my new water system still using a 3 stage RO.
I added these animals. The crab turned white over a month then died, the shrimp lived ( if you could call it that ) for a couple of days then died. I found due to these deaths that my calcium was 1400 and KH was 60. I have been doing max water changes 25-30 gal. once per week for over a month. and using superbuffer to maintain KH at 110-115. But calcium shoots back up from 960 ppm 1 hour afer the cleaning to 1400+ in a few days. I have started removing my crushed coral sugar sand. But is this really the cause and if so what should I replace it with. My local store says this can't happen, but I've used multiple test brands. It is 1400.
