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.
I am under the inpression that RO units create alot of waste water.
For example, 1 gallon RO creates 5 gallons "waste" water?
Is that true?
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.
my whole thing is i dont have any where to hook one so i would have to get a portable one. any one got suggestions on the portable one? i live in housing on a military post and cant really mess with the plumbing.
