    Hello everyone,

    I have been reading many topics over the last few months and I have to say they have helped...Thanks.

    I have a 125 AGA that I am drilling to put in internal overflows (have gotten in the (2) 1.5" drains tonight and have to say I am breathing lots easier) but what I need feed back on is putting in a closed loop circ system. Plan on putting in a 1.5" drain for the closed loop system and (2) or (3) .75" returns. Question is where wouyld you sugest I put them? Drain on the back or bottom...The returns through the bottom or through the back? One thing I want to mention is that I will be using a SCWD for two of the returns.

    Put them on the back. You are drill holes in the tank right?
    If you don't want to drill holes then you can just go over the back glass.

    Do a search on closed loop and there are some cool ideas there that we posted.
