GH & KH Aquarium Water Test Kit Freshwater Hardness TestingThe GH & KH Test Kit provides a simple and reliable way to measure general hardness (GH) and carbonate hardness (KH) in tap water and freshwater aquariums. Monitoring these key parameters helps aquarists maintain stable water chemistry and create conditions suited to their fish. Testing GH allows you to understand the overall mineral content of your water, while KH testing measures buffering capacity. Adequate KH levels help prevent rapid pH

Would purchase again
Size: 48inch, Color: Light Walnut
I was not sure what to expect when I purchased these. I thought maybe they were going to be a fake particle board. But this was a solid wood. Easy to install, no directions were in the box. There was a few chips in the corner of the wood but overall I would purchase again.

Great shelves

Better than expected! Wanted shelving in the kitchen after our remodel but custom cut would’ve cost us over $500. Glad we went with these. Quality is great, easy to mount. I won’t be coming close to the weight limit but even with pressure they don’t budge. Anchored into drywall and 1 stud. Great price and perfect for our space.
