Premium Pack Freshwater Master Test Kit 800-Test Freshwater Aquarium Water master Test Kit

Well respected testing kit that doesn’t disappoint. The titration readings are colorimetric and cam cause confusion between values. Time will help you make judgement calls between values. Very good kit with a lot of stuff included. I’m very happy. Will buy this again when solutions run out.

An excellent test kit. i wouldn't own a fish tank without this kit. it's important for the life of your fish... . to know your water perameters. ammonia, (ph high and low levels) , nitrite and nitrate levels.

The test kit itself is great. The best test kit available. However the unit I received had some sort of oil spilled inside the container ruining the booklet. Fortunately it was a restock for me so the booklet wasn't important and not worth trying to get a replacement.

This is a good kit so much more accurate and easy to figure out how to use it.

Works great and is way more accurate than the strips

Does the job for cycling a saltwater tank

love it works great i will be buying it again

Very accurate good instructions
