adjusting hardness in an established tank

I have 20h tank that is already loaded with fish, but I want to convert it to a live planted tank. The water in my area is very soft so I will need to raise the hardness before I can add co2. I don't want to hurt my fish, so what is the safest way to do this?

Which hardness do you wish to add? gH or kH?

I too live in Portland and need to adjust the hardness. I use baking soda for kH, Epsom salts and calcium chloride for gH.

You want to raise no more than 1° a day of each. See my guide for amounts to add.

Thanks Rex. I have been reading your site and it has been very helpful so far in the planning phase.

I did some calculations, and in order to raise both kh and gh 1 degree in my 20 gallon tank, I need to add approx 1/3 teaspoon of baking soda, 1.58g of calcium chloride, and .66g of epsom salts. Is my math correct?

Also, what's the best way to measure out grams? Is there a conversion to teaspoons that I'm not aware of? Or do i just bite the bullet and get a scale?

Last question (for now), where do i get calcium chloride?

Bite the bullet and get a scale.

Wal-Mart normally has calcium chloride in a couple of different places. As ice melt, but make sure you get one that's pure calcium chloride, and as dehumidification granules. Also most of the stores that carry home brew beer supplies have calcium chloride.

Your numbers look pretty good.
