one of the most important testers there is By Lance on 3/1/2018Lance would recommend this product to a friendI say that b/c chlorine/chloramine kept my corals from living for many years. Using this I know when my chloramine removal carts need changing. Light pink on the colormetric tests can look like clear, and you can be ending up with chloramine and chlorine in your tank without knowing it. Using this along with chloramine monster and dual chloramine pentek carts after I'm secure.
nice checker By moses on 5/31/2014moses would recommend this product to a friendIt seems to work really good I just wish you could use a liquid instead of the powder reagent < its a pain to get it all out. It shows that the carbon filters that I bought for chloramines from BRS takes most but not all out of the system still leaving 40 ppb.
