Has anyone used it? It seems like a good deal and the reviews sound good but I want to know if anyone on here has used it.Right now I only have a liquid ammonia test(api) and I am stuck with stupid strips that test everything else, I do have a liquid ph test(red sea) I got on clearance for $2.00 too so the strips are actually acurate for ph but I have no clue about everything else.Anyways this one seems good and the price is right( I can't spend 30 bucks on testing stuff right now my mom will kill me)here is the link. http://www.walmart.com/ip/Tetra-Labo...ndingMethod=rr
You want a test kit that has test for: ammonia, nitrite, nitrate, pH,
although GH/KH are important most hobbyist will only use it rarely unless you are working on hardness issues.
You don't want to mess with changing the hardness much unless you are breeding a fish species (not Betta) that eggs/fry require certain hardness levels to hatch/develop properly or at all in some species.
