LF: RODI water supply in Calgary

[lastlight]

the di resin works much better in a vertical cartridge in a reg 10" housing. It's much more likely to form channels laying on its side and then you don't get adequate exposure to all the resin.

i just run a single sediment, single caron, ro then di. my media lasts forever i think having so many stages is overkill at least for me.
