How exactly should I go about using RO water?

My tap water has ammonia so high that it killed a Betta within hours (I didn't know at the time, but I do now) and it's somewhere between 2-4 PPM. Once my RO filter is set up, I'm going to use RO water in the tank because of this.

The problem is, I'm using CO2. The PH has shifted between 7.2 and 6.2, so it's getting a little low already. With RO water, it'll obviously drop much further. And there's the issue of having absolutely nothing beneficial in the water for plants.

What additives do you recommend that I use?

Seachem sells "Replenish," it's made specifically for that use.

using RO water

I am new, but found this very interesting, long read, article on using RO water (how, when and why). What do the pros think?

When I want harder water I use these:

Seachem Equilibrium for GH
Baking soda or potassium bicarbonate for KH.

Aquarium plant fertilizers (especially trace minerals) will have 'a little bit of everything' and is a good way to add other minerals.

Get the recipe down so you can reproduce the same water every time.

Seachem Equilibrium is for planted tanks. Their Replenish is not geared toward planted aquariums. This is noted on their web site.

+1

Seachem Equilibrium is a good product. If you want to save some money you can buy some GH booster from NilOCG here on the forum. They both do the same thing. Of course there is no cheaper way to raise KH than baking soda.

Sorry, don't see that. Point me to the place where they say that please.

Read the Equilibrium link. Says it is designed for planted tanks because it has no sodium chloride.
Now read the ingredients in the Replenish link. Includes sodium chloride.

Could you tell me what is the lowest but still safe level for planted tanks in terms of kh, calcium and magnesium levels?

I am planning to set up a soft water tank.
