Unfortunately, I don't know how that one works. With the Salifert, it helps to think about it as the more you use to titrate, the higher the KH is so you can keep track that way. The Salifert chart (at least all the ones I have used) is based on remaining reading so that is where it can be a bit confusing. Sorry I can't speak to the Red Sea as I haven't used that one. 1 Quote Link to comment Share on other sites More sharing options...

chewie Posted February 7, 2018 Share Posted February 7, 2018 (edited) The Red Sea kit I used long ago was way off. I always trust my salifert kits. Haven't had an issue in 20 years. There was a time 10+ years agothat people had problems with but I missed that batch. If yours is not expired, I'd trust it.

Flash21 Posted February 7, 2018 Author Share Posted February 7, 2018 I will keep you all updated once checker comes. I think I have one bad kit as one reads high and one reads low... Thanks for all the help! Quote Link to comment Share on other sites More sharing options...
