I have been struggling for 6 weeks, adding Stability, doing water changes, testing every day because each time I did the results would say ammonia around 0.5 ppm, nitrite zero, nitrate 5-10 ppm. After two weeks of Stability and no changes, I decided to get an API kit to compare. The results are totally different! Plus, the only reason I ordered this kit was that the description said it included tests for hardness, which it didn't. Save yourself some trouble and just get an API kit to start.

Great test kit

Great test kit. I like Fritz because it does not test for ammonia that been bound by water conditioners. The bottles do leak a but when you shake them.

Ammonio test is bogus

Was showing .25 to .50 ammonia on tests for a newer tank and figured it was correct so did many water changes. Still showed the same. Then tested my established

Was showing .25 to .50 ammonia on tests for a newer tank and figured it was correct so did many water changes. Still showed the same. Then tested my established tank and got the same result. Then tested my RO water and got the same result. Tried 2 different brand test kist and show no ammonia for all of them. Maybe i just got a bad batch. The testing is easy and the instructions were clear.

I subscribe to KGTropicals on YouTube. John swears by Fritz and so do I.

More accurate than test strips. Just not as simple. If you have vision difficulties. This is for you!
