You could get that tank to run dead silent with not too much work.
- 2 inch drain seems way big for the tank/sump. Reducing bushings and smaller drain and return lines. Are you positive that your sump can hold all the water in your lines if a power outage happens and they all drain back down to your sump?
- Look closely at the diagram
TexasMFK31 posted above for you -- Durso would not be a big re-plumb job. Also notice the outlet of the drain is 1 inch below the water line in the sump.
-Really? Think it should only be like 1"? I mean, I didn't drill it so that's just sorta how it was. I will say though from looking at other people's setups online I saw a lot of very similar setups with a 2" drain going to 2 1" into the top of the sump that were similar to my tank's size. I'm sure the sump can hold the water, lol. I may not be a setup wizard but I aint that foolish. ? After I set everything up I killed the power to verify the water level in the sump before I finished.
-It's definitely interesting to me. Haven't seen one like this. Is the top of the standpipe actually sealed with just a small tube coming out the center? I find it interesting the water would cope up the pipe facing down. I can see it wouldn't be a huge replumb job but I was hoping the fix would be something minor in the sump chambers, or the height of the standpipe itself. I literally just finished getting this plumbed and won't be draining the whole tank and moving fish to replumb it. I just noticed what you were pointing out. The sump outlet BELOW the sump waterline. THAT I most certainly didn't notice. But it would go against my sumps design since the outlet that comes into the top is no where near the sump water lvl since it goes threw chambers of media and a drip tray area before the water fills the next chamber.
