Yes it is ok.
I just use Distilled water mixed with good car antifeeeze, simple setup 30ltr barrel (25ltr water) with submersible pump dropped in.
It's been in my barrel now for best part of 3yrs and still ok.

4L will be plenty with that ... or you could sell the heat exchanger on eBay and just use a bigger tank. Should be a lot cheaper overall.

...and replace with fish tank

That's how my cooling unit looks like in my PC cooling system after I replaced 3l bucket with fish tank 11l I think:heehee:. 100% pure tap water + antialgae some time ago
