Hey everyone! If anyone is using the Marine master could you give a little feedback? Im considering it. For my testing all I would need separate from it is Mag and Ammonia. It's very tempting because I am getting pretty sick of color charts and not having 7 or 8 hanna kits laying round would be...

I have 4 Hanna Checkers for sale. I have had them for a few months and I don’t use them as much as I thought I would in favor of going to the fish store to get my water tested. They were all used a few times but have all parts including the boxes and some have the sleeves. They are $50 each...

As the title says. Brand new sealed in the box and never opened. $600 shipped to your door.
