Hello
Ive got a 120 reef with a small bioload and mostly LPS and some softies... My calcium is about 500ppm I use RO/DI water and have 0 TDS on the meter How can the calcium keep that high? I also have a 29 reef with all softies and 2 clowns and a BTA using the same water source that I use in the 120 but the calcium in the 29 is only 420. cant see why its higher in the 120. I'm using a brand new Salifert test kit and doing the test right after each other. Any Ideas? My alk is at 7.4dKH and seems to stay there.
