What would you have to do to control the hardness and softness of water in the aquarium2007-11-24 23:43:24

To raise it is just as bad, the ph uppers are basically over priced products that are baking soda .. Sodium Bicarbonate. The toss here is that which part of the PH balance needs to be adjusted, KH, GH or both! There are alternatives besides the spendy chems from the LFS that are cheaper on the pocket book.

Useing bottled distilled or RO waters is not a good idea either,Not for tropicals and Goldfish, remove minerals from the water and you have fish kill/ sick fish and the bio bugs in filters are not gonna be happy either. .

You can find lots of articles on PH,GH & KH in the Best of Forum at Koivet and also at GAB.

To soften hard water, you need to take the mineral out with a water softener, reverse osmosis unit or a specialized chemical that irreversibly binds up the minerals. Another option is to find a source of demoralized water for your fish tank like bottled distilled water.

To increase the hardness of water you need to add marine salt. Increasing the mineral content of your water WILL affect the pH of your tank so it must be done with care, or you can to add a buffer.
