...continued from the
Bidirectional flow thread
(****Post from Kevin at Red Coral)
There are 4 holes drilled in the top brace to accommodate 4 seaswirls,
****1.5" bulkheads
which were to be fed by the 4 holes drilled in the lower bottom back of the tank.
**** I can't tell the size of these holes I would hope they are for 2" Bulkheads
My original sump return was to be determined and because the tank is acrylic I have the ability to reasonable modify it.
**** You can modify as acrylic is easy to drill but with such an incredible tank (do you want to?)
What I would like to do is use only the front two top holes for the seaswirls and drop a couple supply pipes originating from the sump down the back two top holes.
**** seaswirls are an option.
The two supply pipes would alternate the flow, clockwise or counter clockwise in 5 hours one direction with a 1 hour rest followed by 5 hours in the opposite direction, 1 hour rest. Repeat.
**** I personally do not recommend creating the directional flow from your supply lines from your sump..This is where your heaters, filtering etc. are located and do you want to shut that down for an hour every 5 hours. Your directional flow pattern is also where it could become problematic. Do you really want or need to create this flow supply from the sump?
The top zone would be kept moving through the closed loop full time.
I have 1 reeflo dart supergold for the closed loop and 1 reeflo dart supergold for the sump return.
Depending on the results of the final setup, I was leaving open the option of adding the MP60's. The price of them is giving me a lot of incentive to minimize how many (if any) I put in there.
**** If the 4 closed loop holes in the lower back are 2" bulkheads you could then add another dart gold and use 2 of these each to supply a pump and each return would be to one side of the tank. You could pipe in whatever flow and to what areas you wanted. Then with timers you could create your directional flow at the 5/ 1/ 5 timing.
