I think your pump is a Mag 24, the specs roughly add up. If you take a look at this chart, http://www.marineandreef.com/Articles.asp?ID=124
you can determine what flow rate you'll have at a certain height. I personally think you should only pump to the top tanks and have it overflow into each subsequent tank underneath. You'll have the max amount for flow for your pump and you know each tank will have to have the same flow. Maybe supplement with a large air pump and a sponge filter in each tank just for a little mechanical filtration.
Well that old say anyone can be a plumber all you need to know if **** runs down hill.WRONG
Holy crap this was a 12pack job here.I have all the input side mocked up today I am going to start on the over flows
Well today I got all the return lines done and caped off all the holes I did not use.I am ready to test drive this baby,But I don't get to pick up the sump tank tell Saturday at our HAAS fish auction.I am ready though I think hehehehe
Did you glue those return lines onto those bulkheads? If not, I would seriously think about putting some clamps on them..that would suck if one of those popped off. Very cool set up by the way...
