Well maybe one.... I have to ditch one 55 thats leaking and too much trouble to fix. I am in the process of redoing the fish room . cuz our water is so high in Ph. Will keep rare corys and thinking some petrocolas. Don't know yet.
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...
