i got the 150gpd model with a float switch and shipping for like $110. it does not put out 150 gpd but it could be my water pressure so that may be a issue with any brand.
anyways it's 6 stage and i've been running two for a year and both are still spitting out water under 20ppm coming from a tap that's 300ppm. when i first set it up a year ago it was spitting out 0ppm so maybe once a year i should replace the membrane but i'll probably wait another year. replacement's are cheap to. i did a review of this unit on another site i was so impressed with the results considering it's like 1/4 the price of the other units.
oh yeah i have it setup on a 50 gal drum and i run a 50 gal res with 30 ebb and grow pots. in full bloom i'm using 50 gal of water easy with my whole operation. on top of the ebb and grow i have multiple soiless/coco plants, 10 mothers and a 50 site aero cloner that holds about 20 gal of water with just one of these so this thing get's a ton of use. the other i ordered for a friend who has a identical setup and he's having no issues with this either.
im using the evolution 1000 (1000GPD) still takes about an hr to fill up a 55 gal res, also worth noting i saw one in another growshop for a few hundred more that only has a 1:1 waste ratio
Hey, I'd be really interested to know the name of that one with the 1/1 waste ratio.
