Distilled Warter For Top-Off?

[todd2000]

Is it ok to use Distilled water for top off for a few weeks? I have been using the AP Tap Water Filter, and my carterage is used up, right now I hve no job , so it would be cheaper to just but a few gallons of distilled water for like .60, and use those for top-off and hold off on the water change till I can get a new cartridge.

Yes that will be fine to use.

Be careful what brand you use though. I use the stuff from wally world with the blue label ~ always tests out @ 0 TDS.

Some brands may use copper coils in the distillation process.

Good I was gonna get mine at Wally World, I'll look for the blue label

Should be good.

Most companies will use the copper coils in the condenser, IMO. But it won't have a ridiculous amount of copper in it.. at most 1-5 ppm which won't kill/harm invertebrates, IIRC

If theres copper in it will it show up on the TDS meter? Or will it still be 0?

I use distilled water from Walmart for my water changes and top off. It was cheaper than buying the catridges. I have a fish only tank though.

It should as it is a dissolved solid.. meaning it would show up in a total dissolved solid test.
