Got a LaMotte alkalinity test kit in the mail today. 6.4 dkH. I've been under the assumption that the alkalinity was between 7 and 8 with my ELOS kit. I now own 3 alkalinity test kits and I'm going to use Nanook's advice about the LaMotte being the best. Time to start dosing. (BRS Recipe 2).
That PBT looks great in my tank!
