If your looking to get the liquid test kit, the most recomended one is the API liquid test kit. Normally in retail stores it goes for $30-40, at walmart I think I've seen it for $25ish maybe. However check it out online
Walmart.com: Freshwater Master Test Kit: Fish it shows it at $15. the product details says it does
Freshwater pH
High Range pH Ammonia Nitrite
GH (general hardness)
KH (carbonate hardness)
but if you read the comments it does the normal
freshwater Nitrate
fw Ammonia
fw NitrIte
fw ph (lor range 6.0-7.6)
fw ph (high range 7.4-8.)
It's worth a look. My next purchase of this product will be from here
