Nice setup alamo695. Just a word of caution that airating your loop by churning oxygen into the distilled water will increase oxidization of your parts. I'd switch your reservoirs intake to avoid this.
A higher oxygen content in your water may also feed any microbes or algae that would otherwise not exist in the absence of O2, and can cause scumming/filming of your acrylic parts when using certain additives.
You may be fine either way. Just thought I'd add my my 2 cents.
Edit: just saw your follow post. gz.
