I got the new tank I've been wanting for a while, Marineland 300G (72 long x 36 deep x 27 tall) with corner overflows, drilled... Have the eshops WD-300CS sump which is 36x14x16 and coralife 1740P external pump. At head I'll be pushing ~1560 GPH. The sump is only rated for 1200 GPH.
I'm a cichlid guy, have 8 tannks running. The 300 is going to be my "show" tank...
2 concerns that I have; so much flow that filter media will provide enough resistance for overflow from the sump into the stand, and not enough capacity in the sump to account for more than 2-3 days of evaporation. By my rough guess, when the power is cut 12-20 gal drains back into the sump, not much room to play with. Nothing is plumbed, just getting set up at this point.
So, 2 solutions I can come up with: 1, add a reservoir between the sump and pump for more capacity - 2, double up on the sump (side-by-side) and tie them both into the pump and each other.
The first solution in my opinion only solves the having to top off every couple of days and does not address the possibility of the sump overflowing above the filter pads. The second, takes care of both...
2 sumps and it's ~ 600 GPH through each sump, plus double the total water capacity. I would put both sumps into a T then to the pump, plus a loop between the sumps next to or just above the out to the pump so that they have a chance to always be equalized.
If you've done this before or if you have an idea that solves both issues, please share your ideas...
much appreciated!!!
