Zypher Hills Water TDS Question

[dakota9]

At my office, it's not at all convenient to always have RODI water for top off, although I do use it for waterchanges.

This is a small Fluval Edge the requires next to no top off water due to it's design (about 8oz every two or three days). So I've just been using bottled spring water to top off with, thinking it would be infinitely better than tap water.

I took one of my several TDS meters to work today, and tested the tap water, it came in at 45 ppm TDS. Not great, but I've seen worse.

I tested the Zypher Hills water that I'd been using (I realize Spring Water and Purified Water are two different things), it came in at a whopping 129ppm TDS. I was very surprised!

Now, I know it's not JUST TDS that matters, but of what what that TDS consists, as if 15 of those ppm are copper, then I've pretty much killed everything in my tank.

My question;

Which would I be better off using if RODI is not available when I need it?

I doubt the bottled water has a high metal content, but at 129ppm, it certainly has a lot more other stuff than the tap.


And I agree, I should keep RODI on hand!

Thanks,

A little nitrate, but no heavy metals to speak of.

you can always get a brita filter and remove the carbon and stuff some DI resin in there.

How about taking a old milk jug with RODI water from home.... that should be about a one month supply of top-off...

Everything I keep for my tank needs to be kept in one file drawer (afterall, I'm supposed to be at work, LOL)

We have a brita pitcher here, maybe I'll just use water from it.

I could get a one liter bottle and use that for some RODI, that would fit in the storage I have available to me.....
