Grizz's 300 gal 8'er / LED Heat sink build / Opinions on LED lay out needed

[The Grizz]

Well I will continue in this thread for now but will start a new one when a actually start building the system.

As for the pumps, I wanted to see how they ran so I took one into my pool room & dropped it on the second step, plugged it in & fired it up. It was COMPLETELY silent running!! Then I wanted to test the flow so I attached a 1/2" hose that was 25' long, got a water jug & timed the flow rate at low speed & high speed. On low it was flowing at about 360 liters per hour & on high it was 1080 liters per hr.

Now the thing to remember is that the max head is 5 meters ( DC 10000 model ) & the outlet & inlet are 1 1/4" ports. I also didn't realize that these where submersible pump so I will have to change up my plans a bit but all in all it just mean less holes to drill in the sump & less chance of leaks in the plumbing.
