Does heat affect RODI water?

[moreef]

I’m planning to store my 5g containers like these with rodi water in my garage in Texas where it will be way over 100 in the garage. Y’all think this is ok and won’t leach anything from the plastic? They say don’t drink from plastic bottle left in hot car so kind of wondering if it’s safe for the fish lol.

If it smells, it is releasing organics from the plastic. That doesn't mean they are a problem, but is worth noting.

Anecdotal contribution…

I live in Phoenix and have had in my garage for about 5 years now, a 65g reservoir for RODI water supplied by a 4 stage, 75gpd unit with a TDS meter.

I have never had any issues with the quality of the RODI output, lifespan of the filters or resins or unexpected contaminants. (I do keep the extra resin inside however).

The garage is routinely > 110 deg in the hottest months. At night, it does not drop below 90 deg. This weekend, ambient temperature was 118 deg outside of the garage. And when someone pulls a car into the garage….well it’s pretty friggin hot in there.

I would consider these “extreme” conditions and no issues that I am aware of.

I keep my RODI and storage outdoors and never had a problem with membranes or cartridges. Now I did replace my unit after about 9 years because heat and/or UV starting breaking down all the fittings.

The water isn’t hot my garage is.

It's the water temperature that is of concern

If you mean chlorine kit, any one should be fine, but you might want to be sure it it intended for aquaria and not hot tubs where the needed range might be higher.

I meant tds meter

An inline meter is easiest to use.
