gypsum in water
At my new place the water seems to contain a lot of gypsum. I'm still
trying to guess how that is going to affect my new tank in the long run. I think it might be harmless as the local nursery sells the stuff as an inert additive to garden soil, but it leaves an unattractive grey-white deposit on the bottom of a test bottle I just evaporated. In the water heater it separates into sulfur and calcium but I do not think that is going to happen in the aquarium. |

My GH and KH are both 7, so the permanent soluble salts must be very low. I think I should have realized that from the fact that this grey powder is not all that soluble. I know there is some gypsum because the hot water faucet releases H2S when I open it, but the amount must be small. This residue must be magnesium carbonate, or "chalk." I'm going to have to look up what this means for my tank. |
