During last months group buy I picked up this item
150 GPD Water Saving Upgrade Kit - English
I have the BRS plus ro
unit and it only makes like 3 gallons of water an hour which was not cutting it what with all my tanks. lol
It took a month to install it but now it's up and running. I have to say it seems like a great purchase so far. I am now making over 6 gallons an hour and the waste water has been cut in half.
Here is a picture of it all installed which believe it or not was not difficult at all other than I had to take the unit off the wall.
If anyone was thinking of getting the same add on membrane and you have any questions just ask.
