## Description

API GH & KH TEST KIT Freshwater

Review: Nice test kit to test general hardness and carbonate hardness of the water. - This is an essential test kit for fish keeping as it will determined the general hardness and carbonate hardness in the water. I use ro water for my fresh water tanks which gives the pure form of water. Then I mix general hardness enhancing solution like seachem equilibrium or seachem replenish to make water with desired gh level. Then I use seachem alkaline buffer and acid buffer accordingly to maintain the proper carbonate hardness and ph for the specific species tank I'm using the water. This kit comes handy in checking the final gh and kh levels before adding the water in the tanks..
Review: Very good product - Very accurate and extremely easy to use. I use RO water for my aquarium and these readings help me maintain my parameters as desired. Very good product!

Very accurate and extremely easy to use. I use RO water for my aquarium and these readings help me maintain my parameters as desired. Very good product!

### ⭐⭐⭐⭐ Excellent test kit, but not worth buying for individual use!
*by V***H on 31 May 2017*

I purchased this kit thinking that it will be very useful in aquarium water testing, and I used it a couple of times. It helps in determining the hardness and type of hardness, of the water used to keep fish, but honestly now I feel it was a needless purchase, because once you know about the hardness of the water the kit is not of much use again. Afterall we do not use different sources for the aquarium water, almost all of us use the same source after deciding the suitable water or mix of water from different sources. Being said that, I found the kit is very dependable and results are accurate. Even though I used only a couple of times it has helped me in deciding which plants and fish are suitable for the water which I use in my aquarium tanks, and whenever I had bought not heeding the results those fish perished and plants did not flourish!
