I "finished" mine as a sump room:
- Tapped the H&C plumbing
- Added a HD stock counter and sink on an open frame with shelf, added a single faucet for dedicated RO feed
- Built a sewerage ejector out of a Brute with a float switch
- Hung a plywood backer board to mount all of the equipment (RO, UV, Media, Controllers, etc)
- Installed a 7 stage RO/DI and RO/ALK (drinking water) system (soon to be 8) with 12volt solenoids
- Built a 55 gallon sump with dual returns on a 2x 6 stand (I have some strong opinions on sump design including low-flow refugium and 100% flow through MarinePure Spheres
- Set up RO storage and mixing station
- Built a manifold on one of the returns with single value turn water changing
- Installed 4 head doser (2 head used for RO water) which takes the heavy load and provides a back-up to my home made $20 ATO
Never has tank maintenance been easier than with a full lab, no crawling under a stand and a concrete floor tha t can get wet.
Built this all for a 60 gallon cube display with the knowledge that I would be upgrading. The SCA 120 went up last week
Happy to help anyone with questions
