Free DIY Ro/DI unit... I say DIY because I took it all apart to clean it out and never reassembled it 6 years ago. It needs all new filters and probably a ro membrane ..but it's free! Membrane that was in it is 50 gpd. Comes with the wrench to put canisters back on. Bought it from fire and ice...
That's a heck of a project there! I couldn't evem dream of trying to take care of all of that...and my 13 tanks...and yard work...and working LOL!! Nice job though
