Now it's football playoffs so the time with help is even more limited. I won't be gluing tubes together while greenbay gets their butts kicked by the giants!

Reading a couple of post above, it looks like you will need a reservoir for your RO water then from the reservoir to your sump. You will need a pump in your reservoir to pump RO water to sump, in the sump you should have a top off controller to active and deactivate the pump. Also, in your reservoir another controller to turn on and off RO unit. Therefore, with a tank your size get as big a reservoir as you have space for. I go through on average 2-3 gallons a day with my 180.
