I have about 30 corals in my 125g and about half dozen sps, nothing crazy. lol
The hanna checkers are usually anywhere from $50-$55 dollars usually. So I just did the alkalinity with both salifert and the hanna. came up with 8.3 dkh for the salifert and 9.3 on the hanna.
Now for the crazy stuff. lol I must not know how to use the calcium checker cause i came up with 600+ in the 125g, 566 in the 20g and 600+ in the biocube! With the salifert the 125g is at 400ppm in calcium.
Anyone have any tips on how to use the hanna calcium test? I followed the directions but I must be missing a step something.
