Not a big deal at all, I haven't used DI for years. Vancouver has soft water and not anything to be concerned with.
Algae could be diatoms, but being stringy like that, I'd worry about dinoflagellates. These are bad. Google and see if it's the same.

Not sure you'll need a chiller, but if it does kick on, the heat it puts out might be an issue under the stand like that.

Otherwise, great looking setup!
