I to thought it was never going to happen but it is on like donkey kong now.

It was a very ingenious thought I had for sure, wasn't sure how at first how I was going to get the bottom of the OF set but I hit me like a bad case of the tropical runs.

ABSOLUTELY NO closed loop, those are all return lines.

Yes I have read up a lot on the BA and most are only taking on 2000 gph, I will be pushing A LOT more flow. There is going to be 4 DC10000 pumps for my returns that way I can control how much flow I get in every 2' of tank length.

Did you not like your closed loop system on the 165? Why would you not do it again?

I'm planning my closed loop right now and it would be nice to know why you chose not to do it again lol.

FYI you could plumb that tank in a way to prevent it from draining without the need to rely on check valves or batteries. You could also run some of the pumps inline with the overflow to form a "sort of" closed loop, it would prevent the massive amount of sump turnover I can't help it, I just can't take it anymore, I need to know your plumbing plans. 4 return pumps and glass that looks like swiss cheese, if that doesn't get you existed nothing will

So far all we know is that those holes are for his closed loop.

NO DAMN IT!! NO CLOSED LOOP!!!

Looking great Grizz, can't wait to see the front pane on!

[fishytime]

looking good Greg....so where do the other two tanks fit into the picture?

Ok Steve I will give you a quick run down..........

Going to have 4 Dc10000 pump each with a 1" SCWD for every 2 parallel holes. Going to set the SCWD's so that the flow is alternating opposite the hole on either side. Now I know that they will probably not stay in sync but the flow will still be different every 2' instead of constant the whole length.

Why not just skip the SCWD and build a controller to alternate the each pump cycle.

Less to go wrong with the SCWD then going though all the trouble to build a controller and it not work right. Plus the DC pump ramp up slower then most pumps as you know.
