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.

Works great, super easy to read, love the size of the chart on the back!

Nice

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.

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.

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