Aquarium Water Hardness: How To Improve Your Aquarium'S Hardness (And How To Do It)
Aquarium water hardness is measured in general water hardness (GH) and carbonate hardness (KH). This is also referred to as alkalinity. The general hardness is 10 mg/L CaO, which is equal to 17. 85ppm. Carbonate hardness is related to the aquarium's pH. Unless you invest in specific tropical species that must live in soft water, your fish will likely adapt to the hardness of the local water in its aquarium. You can bypass the whole issue of whether your aquarium will thrive in hard water by choosing a hard water fish species. If your chosen species of fish must have hard water, they should change water sources instead of using expensive ongoing water treatments. Using reverse osmosis (RO) water to blend in is one option. This is done using a combination of tap and distilled water. Some industrious aquarium owners have been known to collect rainwater. This can be hard. When buying fish, check with your local pet shop to find out what the hardness and pH levels are for their tanks. Crushed coral or shell or crushed coral can harden or soften the water. If you use any sort of extra water to harden the water, make sure they've been cleaned. . . .
