I purchased this Mag5 from Nancysalt a while back, and have gone a different way with my setup. The overflow is custom from a local reefer and is estimated at 300gph, it has 1 J tube. I am asking 90$ +shipping for both. I will include all the tubing, fittings, and clamps I bought for this too. Note though that the larger tubes are short, for sqwds and split return.
