I have a 55, and my sump/fuge is also a 55. I currently have a 750gph Little giant pump,
and a 350gph overflow, but , it's just not the kind of flow I want. I can't turn the valve on
the pump to full flow because the overflow won't handle it. I would guess that each of the
4 outlets in the tank is exiting about 87 to 88 gph, as the overflow is maxed out.
I will be installing a Rio hyperflow 20 pump this coming week, it produces about 990gph at
4ft and only pulls 60 watts. and these new Rio pumps use no oil. I've had a Mag, and it
internal shorted about 6 months after I got it, and I have known others who have had
the same issue with Mag's.
I figure with the plumbing, i'll loose 90 to 100gph so I'll have about 222 to 225 gph
coming from each of the 4 outlets in my tank, so It'll be like having 4 maxijet 1200's.
In addition I have installed 2 hydor rotating flow deflectors on the top two outlets,
in the tank. Even if I were to loose 25 to 30 percent of the 990gph, the flow would.
still be about double what it is now. I'm using as much flexable tubing as possible
to reduce 90 degree bends, which is the thing in the plumbing that eats your gph
the most. With the current plan there will be 4 90 degree bends.
All that will fall back through a CPR 1600 gph overflow (yes I have the aqualifter), that I
bought used on eBay. IT's big, but I thought it would grow with me should I decide to
get a bigger tank, and it was not drilled.
I have all the stuff, and I'm off on vacation this coming week, so me and my brother
are going to install it all.
I've been told I should use the SEIO's to add flow, but I just don't like power heads in
my display tank.
