Tetra Test NO2 & 6in1 + GEX Activated Carbon Cartridge

This is a set including water quality test kits and activated carbon cartridges.

We were raising and keeping a Chinese pond turtle, but it will now be kept at an elementary school.
We are listing items that will not be used at the elementary school.
