Freshwater Aquarium Test Strips 6 in 1 - Fish Tank Test Kit for Testing pH Nitrite Nitrate Chlorine General & Carbonate Hardness (GH & KH) - Easy to Read Wide Strips & Full Water Testing Guide, 200 Ct

I am an environmental science teacher, and I use these every year for one of our experiments. These strips are easy to use and are great for our purposes. However, they do have an expiration date, and Amazon does not pay attention to it. Three times in a row Amazon sent me an expired product despite me indicating so on the return form.

I love that it shows you the correct level you need for the fish tank.

The strips are easy to read and seem to be very accurate, not as thorough as the full kits but will cover most of your standard tank issues. Will buy again

These I absolutely love them. They were easy to use very simple. I absolutely love these. I used them on my pawn. And I used to move my fishing tanks. So they are pretty d*** close to the liquid ones.

Not accurate to other 6 in 1 aquarium test strips. Not easy to read, bleeds into other tabs and the colors are not accurate either with the bottle they send as the control. Do not purchase, the xtra packages they send are not aquarium strips, not sure what kind they are but they are not Aquarium strips of the same kind as control. Waste of money sadly missed my return date by a week since I was out of town and didn't try the additional packages sent prior to the cut off date. Will not purchase again.

Overall, they look comparable to any others i've seen with better value.My kids can use them with ease on their tanks so testing and water changes get done appropriately i.e. before a real problem shows.

Test strips are as described. Basic and very easy to read for a quick test. Plus of this test kit is that they are packaged in 50 count strip packs so your strips don't go bad sitting in the open air or by accidental moisture.

Everything was as advertised. No issues

Easy to use and a great value. I would definitely recommend this product!

We are january 21th, 2024. I received it today. It was already expired (date: november 10th 2023).I will probably return it, but nothing can garantee me that the date would be ok If I buy another one.

Easy to read and use.

Won't test for alkalinity and ammonia. Also, colours are inaccurate. Never buy cheap products who have a specific purpose but uses irrelevant points like "easy to read" as a sales pitch.The colours aren't even accurate on the bottle, doesn't matter how big you make the strip, it lacks accuracy and advertises 7 in 1 on the basis of chlorine while completely disregarding ammonia (the most important).These strips are a rip off, they are not meant for aquariums requiring specific readings. All fish require different parameters, it definitely doesn't help when they can't give you a proper reading.Cheap product meant to make money off of but the creator doesn't use or know the purpose of.

The strips are fast and easy to check. I have compare the strips against the normal liquid tests and they produce the same result as the liquid tests, but much, much easier and faster.
