    Default How are you getting Flow in your Tank ?

    This Thread ties in with the,
    Under / Over Skimming Thread.

    Is the only Flow in your Tank provided by your Return Pump ?


    Are you using your Return Pump with other " In Tank " Mechanical Equipment ?
    For example: Power Heads, Tunze, Vortech.

    Are you using your Return Pump with a Closed Loop System ?

    I run a closed loop. Snapper on an om supper squirt. And a vortech Mp40. 100 gallons.

    I try to get most of my flow via vortechs, closed loop are great too, though I've never used one. Personally I think most people run too much return flow, it just adds extra to electricity bill and adds more heat in the summer.
    I run an ATB 1500 flowstar for return and it also feeds a media reactor and flows through my chiller with a head of about 4 foot. I would say that I am running about 800-900gph on my 180g for return coming out of a 100g sump, total volume of water is a little over 200g. So I suppose I am right around 5x turnover on the return more than enough, I have heard 3-4x is sufficient.

    I have a Mag 18 for my return. My tank is a 180. But, the Mag 18 has to go up 11 feet and across 13 feet. So, it is down to about 400 GPH. So that's not enough.

    For my main flow I use a pair of MP40w's One at each end.
    I will think outside the glassbox.

    I bet thats plenty of return flow, if you aren't having trouble then its plenty. Well imo.

    In my 65 breeder-

    I am running my return at about 150 pgh.

    I have a kotilia evolution 1050 running constant, rippling the waters surface.

    I run a vortech mp10, set on reefcrest at about 70%.

    Looking to get 2 more evolution 750's, and put all 3 on a wave timer pretty soon, on 20 second intervals, back and forth from right to left. I will then mount the vortech on the back of the tank to randonize the flow up a bit.

    I need a higher turnover rate for heating. Otherwise my tank drops to 74.3...

    That could be another thread in itself.

    Turn over rate used for Cooling or Heating purposes
