KH/GH question.

My KH is 6 ppm and my GH is 10 ppm. Is this normal? I thought that they would reflect relatively the same results. Should I bring my GH down. I have a 90 gallon planted tank with Rainbows, Angels, Rams, Killies, Gouramis, and Tetras.

Excuse me, 6 dH and 10 dH, not 6 ppm and 10 ppm.

The two are not connected that tightly. You can alter one without altering the other (for instance, water softeners remove GH but not KH). "Normal" means a lot of things. Your levels are fine if a little on the hard side (GH). Nothing to worry about/alter.



72g bowfront planted, CO2, 4x - T5HO, Eheim 2213 and 2217, 2 angels, pristella tetras, blue tetras, betta, albino bristlenose pleco, albino cories. Sword, vals, hygros, ludwigias, java moss and fern, anubias

2g Mac-quarium. Clown gravel, fluorescent plastic plants, and 2 guppies.
