Antifreeze recommendations

[mmesqc1578]

I am looking for recommendations on what ingredients to look for/avoid in pool antifreeze. I see Walmart has a great price and it claims is "non-toxic." It does contain water, propylene glycol, glycerin, corrosion inhibitor, dye.

Home Depot has two options:
One contains PG but is glycerin free. Is there any reason to avoid glycerin:

PRIME GUARD 128 fl. oz. PG Formula and Glycerin Free -50°F RV Antifreeze 95006 - The Home Depot

PRIME GUARD minus 50°F RV and Marine Premium Antifreeze is a propylene glycol (PG) based product blended with a proprietary additive package. Our patented Acra-Blend Process ensures that every bottle is blended to exact specifications. This is critical as this product is typically used to...

Other contains ethyl alcohol which sounds like I want to stay away from:

PRIME GUARD 128 fl. oz. Ethyl Alcohol -50°F Universal Non- Potable RV Antifreeze 95806 - The Home Depot

PRIME GUARD minus 50°F RV and Marine Antifreeze is a premium winterizing formulation safe for use in all types of potable water and plumbing systems. This ethyl alcohol formula is safe on copper, brass

The proper type of antifreeze for pools is propylene glycol (RV antifreeze). Be sure to NOT use ethylene glycol (automotive antifreeze).

Thx. Any reason to avoid glycerin in addition to PG?

I believe glycerin is a byproduct in some of the pink RV antifreezes. Maybe we can get @JoyfulNoise to confirm.

I like the brand of RV antifreeze Lowe’s has. It’s under $4 every year.

one by you was out of stock but the other 3 Lowe’s had 64-200 gallons each.

Is this the one from lowes?

I would stay away from glycerin based antifreeze. Bacteria can use glycerol for energy (food) and it can be converted by chlorine into many different chlorohydrin compounds which are not healthy to be exposed to. Further chlorination does not break them down but makes them more toxic. As with any antifreeze, do not get rid of it by simply dumping it into the pool when you open. You should have a procedure for capturing and disposal.
