Hello,
I am not good with drawing online, but I will try to describe the best I can.
Can you split the drain lines so that one drain line goes to one end of the sump, and teh other drain line goes to the other side?
If so, you may want to think about this method...
By placing the fuge on one end, you can slow down or adjust the
flow rate through the fuge. Some peeps like a very slow flow through the fuge to allow pods and other growing things a chance to grow before being flushed or swept into the pump area.
Then, after you figure out what configuration you want the sump/fuge, (FUGE-RETURN-DRAIN, vs DRAIN-FUGE-RETURN) Then you need to figure out how much water will drain back into the sump if there is a power failure.
There is a couple ways of doing this. The most accurate way is to run the drain line into the sump, and turn off the power and mark a line from before the power went off and where the water line ends up. You can eitehr measure how many gallons by scooping and measuring, or you can use math.
Measure the width x length x height of water, (between marks), then divide by 231 = Gallons of water that will drain back into the sump.
OR, you can estimate how much water will drain back into the sump by measuring from the display tank, the surface of the water at normal height, and to the (inside)top of the return pipe. (The inside of the pipe)
This is the point where air will start to go into the pipe. This could be the bottom of the teeth of the overflow walls or the HOT overflow or whatever you might have, (again, this is an estimate)
And using the same formula as above, lenght x width x the distance from the top of water at normal, vs the top of water at the bottom of the teeth, or the inside top of pipe of the return pipe.
Once you have the quantity of water that will flow back into the sump, you need to use that formula again, the only difference is you now know the number of gallons, but need to find the height
That formula is Height = gallons / ((length x width) / 231)
NOTE: you should reduce all your measurements into inches
After you find the height of the water that will flow back into the sump, mark that height FROM THE TOP OF THE SUMP DOWN.
This is how much room you need to leave in the sump in case of power failure.
NOW, you can figure out how tall the baffles will be by measureing from the bottom of the sump to the new mark. I would round the measurement down as much as you can afford, ( half an inch or more at least, )
Next you have to figure out a couple more things,....
