Great Ammonia Test Kit! By Dean on 12/8/2014Dean would recommend this product to a friendHaving become frustrated with three or four different Ammonia test kits I made the plunge and got this one. Accurate, yes. Ease of use, yes. Results that I can count on, yes. Repeatable results, yes. Okay it is a little more expensive but I was getting so many mixed results with the other brands of kits by the time you add up the costs and frustration it is well worth it. Now I wish I would have bought this one first and saved lots of wasted money on the less expensive kits.
Ask a question
Have a great day!
i was wondering if this ammonia checker although it is stated that is for fresh water, can it work with saltwater as well?
would it be as accurate?
This ammonia checker is only compatible with freshwater. Its generally used by people with saltwater aquariums who want to check there tap water for ammonia content (which would be indicative of chloramines being present in the water).
