Which antifreeze safe and affordable

I finally got the time and weather to get the solar water panels on the roof. I have it hooked to the pool for now. Will switch it over to heat the house by this fall. Still need to run lines to the water tank. Also angle them for best winter sun.

I need to start thinking about antifreeze, to treat 500 gallon for 10F about -12C. Which antifreeze eco-safe and affordable? Wondered if anyone had a brand or type to recommend.

My brother, talked me into re-soldering the panels serpentine instead of grid. Thinking being better heat gain.

Nuisance the cat. Giving the final inspection.
