Hey members,

Just want to know what's the hardness of the water you guys keep your guppy in?

Just tested mine. This is the last test kit I bought gradually. I read that guppy's live optimally in water hardness about 10-30 degrees. Is that true? Well all my tanks only register about 2 degrees. Alamak way out of range. If that's true I have to get sodium bicarbonate and increase the hardness..........
