I used the Freshwater Kit for our 55 gallon fish tank. It provides excellent results and in the end it saves money since you don't have to take the water to the fish store. Very good product!

Pros: fast results,

Cons: expensive,

I kept these on hand and used them often. You have to keep an eye on the water quality in aquariums and this testing kit is the way to do it. A high nitrite level will kill the fish so this is very important.

Pros: A must for aquariums

Cons: none

The set-up is very easy to use.I have one for saltwater to.Better than buying them seperate.easy to store away.Saves on gas:).Use it once a week to keep your water in good condition.

Pros: Can reuse

Cons: none

I used to use this testing kit alot. I fidn it is better to just leave my tank alone. the new test strips work so much easier

Pros: okay

Cons: none

Easy to work with. I have been using this for years..

Pros: Easy

Cons: Non
