How long have you used Kent? I used to use it years ago, but then the formula appeared to change. They sold the contract or something??

Been using it since the beginning of the year. Am on my 4th box now and am happy with the result so far. The numbers on a fresh mixed batched (after 24 hours) are a bit high but my system seems to be on par.

Been using RC since times gone by, might switch this time though I find the alk and Ca too high.

I use Tropic Marin.

I use H2ocean. I used to use IO,but I got a bad box once and I never gone back. H2ocean has been rock solid for me for over 2 years now.

I use H2Ocean. I don't have to dose a single thing and it mixes crystal clear.

Royal Nature here. It dissolves extremely easily, a few stirs and it's a done deal. Very happy with it.

I use Tropic Marin Pro

Royal nature here..
