Aquarium water

I usually buy water from a machine at one of the Kroger grocery stores. You bring your own water jug/bottle, and there are three ways the machine processes the water to make it pure, more cheaply than the classic "distilled water." It costs half the price of a similar bottle of water still sealed at the store.

I asked Ruby to get some water, and poured some of what she brought into our tropical fish aquarium. I expected her to get some from the machine

I just noticed that the water she brought home says it is municipal-source water (tap water, essentially) that has been carbon-filtered and ozonated.

I'm sure that the water machine water had three processes, not two. I'm wondering if this water is pure enough for my fishies.

I do have a carbon filter and bio-filter on my aquarium. I want any water I add to replace evaporation to be essentially mineral-free, so that the minerals in the water do not become increasingly concentrated.

[Yes, Marymary, I could look it up, and will do so if no one volunteers information. But it may serve as a topic of conversation here.];)

I remember when when we had a sub-forum dedicated to pond fish.

Well, I'm not an expert but we did have some fish once. What I learnt was that you can use tap water but not straight away. You have to splash it into the pond/tank to get the flouride and stuff out and then leave it for a while before puttting the fish in. Or you could fill a bucket with water from a great height so it splashes a lot and then leave it a day or so.

But what do I know.

You are correct, John. It's years since I had fish, but tap water can be used only after being "sterilised" by letting sit in a bucket for some time and the addition of a chemical neutraliser for the chlorine and flouride that was added to our water. (At the time I lived in the tropics so chlorine was necessary to minimise algal growth.) Be aware that the water temp must also be equalised with that in the aquarium.
