So today I was in a store called “Let’s Make a Deal” where it’s nothing but liquidation from major chain stores, I looking for something to turn into a aquarium stand for my new “used” 65 gallon tank, I found a corner cabinet that I liked, I plan on making a top for the cabinet for the aquarium to sit on, the cabinet is 3’ 2” wide by 21” deep and the tank is 3’ wide and 18” deep I didn’t do any measuring till after I purchased the cabinet for 20 bucks so I feel like I hit the mark pretty good, but also I came across an APEC RO 90 water filter that I talked them down to half of advertiser price on the internet. I have an RO buddie RO DI filter that’s been running slow lately but the DI filter hasn’t changed colors yet so I rigged it up on the APEC RO 90 system, my next question is would it be worth the time to replace the membrane on the RO buddie and run two membranes? Or would that be an overkill waste of time?
