nalu86 I have a PWC 5 stage RO unit.
After 6 months I had to replace the membrane, ppm was up to 42 and my water out of the tap is 58ppm. imo membranes from PWC are cheaply made.

Now I have a Dow Filmtec membrane and I have a TDS of 3ppm, I wonder how long it will last.

I added a cartridge for increasing the alkaline level (adds calcium and magnesium) thats connected to my fridge. Also have 2 other outlets for normal RO water and DI water.

somewhatshocked RO/DI filters separate everything from water. All dissolved solids - dirt, calcium, et al - exit from the waste water point. Pure H2O (0 dissolved solids) flows from the other point.

My 150GPD products 3-4 gallons of waste water during the summer. During the winter time if you're in a colder climate people run a longer tubing through a heated bucket of water to improve efficiency. Also your water pressure needs to be high enough too or it won't be efficient.

I noticed that using too small of the filters for the sediment and carbon dramatically increased the time and also increased the waste water some. I already bought too much 1um filters... I'd stick with 5um sediment and carbon blocks.

somewhatshocked Depends upon the membrane you're using.

If you've got a cheap one? You're likely going to waste a ton of water.

Most efficient membrane = most expensive.

morgan I paid £30 / 48 USD for mine and it works perfect. 3 stages of filtration gives me 12ppm with zeros on gh and kh. Not too sure if im gonna expand to a add on DI filter, as my fish / shrimp breed fine without.

ravensgate I think hubby ordered from Bulk Reef Supply, it was a 3 stage unit they had on sale for like, $140 I believe. It's not hooked up or out of the box even...Christmas gift and all
12-13-2012 02:03 PM
Lisa816 Just wondering which RO unit you ended up ordering, and if you got it hooked up yet, how is it working? I'd like to get one for Christmas too and not sure which one to get.

somewhatshocked Trust me - it's better to feel dumb than to actually make a big mistake when something simple can be avoided.

That's what's great about TPT. Always easy to find an answer or get an answer regardless of the issue.

ravensgate Tis true, tis true. But sometimes I REALLY feel dumb after the answer is revealed. LOL! Thanks for the heads up on that unit Jake, you are AWESOME!
