View Full Version : RO/DI and auto topoff

What type of RO/DI and auto top off system would you recommend for a 150g mixed reef and 40g sump? I have no area for a "tub or Rubbermaid trash can" due to my tank being in the dining room. The kitchen sink is approx 25-50 feet away. I have no basement either. Is this possible to setup? If so, how?

Thank you in advance for your suggestions.

all you need is a float valve in your sump and a RO/DI unit with a shut off solenoid. This simple set-up doesn't rely on a series of eletric float valves, or electric pump...just h2o pressure and gravity. rodi unit takes up very little room and only needs 1/4 inch h2o supply line to run.....easily run though hole in floor and tied into existing pipe already running under your house with a $3 saddle valve
