My DS1 TDS Meter shows 386 TDS after the 3 pre-filters.. My water softener went out and I just got a new one installed today. So I will recheck the numbers tomorrow.

I got an 800 flow restrictor running 2 membranes in series. Which gives me a ratio of ~2.68 to 1. If my calculations are correct? Though I know I wont actually get 300 GPD, so that ratio is actually a bit higher? I Should be 80 PSI after the booster pump.

I am rebuilding my entire RO. My primary reason for dual membranes is to increase production, though the using less water is an attractive side effect.

Also I am changing from a 2x10 "inline" DI filter, to a 2.75 x 9.75 "Cartridge" style DI filter, I don't know if that will make any difference in my DI filtration/volume, but If I'm not at 0 TDS, I will add a 2nd "Cartridge" style DI filter. There is also the possibility of going to A Dual DI system, 1 Cation and 1 Anion cartridge, but that may be over kill..

Thanks!
