I found the menards by me in northern chicago (on route 12 and 53 north) has aquarium water test kits for $7.50 on sale by the pond stuff as the season to add a pond is slowly going away up here.
The kit if for fresh and marine and does PH
, Ammonia, GH
, and Nirite. There is like 30 test worth of these.
Compared to the other tests kits I've seen this looked pretty cheap. I compared to the other test I had recommended by a LFS
and it was the same results and the same price at the ammonia test I got for same number of tests.
I don't know the make of the test offhand and I'm at work so can't check. I can add latter if someone wants to know.
