Cool! Took me over a hour for 5 gallons as well so I guess im on track!

Ive had this RO unit installed in the house for 3 yrs but its really only been used for drinking and cooking with the occassional gallon or two top off on the nano. Not so much for water changes so thats why after all this time im asking these questions. Really just tired of buying water from the store, so I thought its time to take advantage of having what I already have and change the membrane and filters.

Tonight i have figured out when I want to do a water change its best to get the water started days in advance just so that I have enough, lol.
