9 in 1 Aquarium Test Strips for Salt & Freshwater, Fish Tank Tester Kit for Iron, Copper, Carbonate, pH, Nitrate, Nitrite, Chlorine, Total Hardness & Alkalinity - 100 Count

Received the test and checked my water levels. Strips are very easy to use and give a quick reading. These strips test for more harmful levels in the aquarium water. What I like about these test strips is that they compatible with fresh and salt water tanks. If you have both, no need to buy 2 different products for each water type. Great product for the price. Highly recommend these test strips.

Very accurate and easy to use

Don't know what was going on. some of the test strip had the tabs fall off or didn't have anything on them. but lucky it didn't come off in the fish tank.

I’ve been looking for information that tells me proper levels and when to change and goes into more detail. The strips are good quality and the info sheet is nice and laminated. Very pleased. Whatever reactant is used in the pads, it is better than the stuff used by API as it provides a much more broad range of results. Particularly for nitrate and nitrites.

No me agrado ya que no tiene literatura para saber los range a seguir. Como ejemplo para peces tropicales cual sería la medición correcta.

Bought these to help me set up my new 75 gallon freshwater tank and I love them. They are very easy to use and you get your results in exactly 60 seconds! Honestly some of the best test strips I've used in the last 10 years. Thanks for a great product!

Item description says testing for ammonia and phosphates but it does not test those levels.

I’ve had freshwater tanks for years but recently started salt and I’m glad I found these strips that give a lot more info than other kits. I appreciate having the details for iron, copper, hardness, and alkalinity. The instructions are easily followed and color chart is easy to read. Thanks for a great product!
