Anyone use it?

Im a very big fan of changing water and am currently using TMP. No junk, mixes clear and fast etc. But it carries quite the premium.

Seems like RPM is similar but a bit cheaper.

Any vendors sell it locally? Interest in a group buy? I’d love to try and get the price down via a group buy and stock up on it.
 
I went from TMP to Brightwell Neo-Marine and am tickled pink, lol. You can find them for sale as low as $55 a bucket at times. Just picked up 3 more during Black Friday.

2017 grams equals 15 gallons of finely mixed saltwater at 1.026 My calculations

134 g per 1 US-gallon (3.785 L) of purified water yields a specific gravity of ~1.025 g/cm3, with a pH of ~8.30 and alkalinity of ~7.5 dKH
