New tank design graphic ... Tell me what you think...

Where are you keeping the reactors? I don't see enough room under the stand...?

Only a third of the return water from the two overflows will be going through the refugium first. One return goes directly to the sump, and one goes into the refugium. To reduce the refugium flow even more, I have the ball valve (E).

Since pods are of a concern, I could always put the refugium's overflow output hose (J) into the last compartment of the sump (N instead of K) so that it will bypass the protein skimmer and reactors in the main sump compartment.

There might be enough room for the kalk, protein skimmer, carbon, and GFO reactors in the sump, while the sulfur denitrator could be used intermittently in front of the sump. (There will be some space in front of the sump and refugium). If there isn't enough room, I could just put the carbon and the GFO in the same reactor. Another option is making a DIY acrylic sump that is 17" wide and 26" long, which would surely have enough room.

Oh but then bubbles will get in there. Maybe I could somehow direct it into the baffles (M) instead.

On another site I have seen where the output "J" from the refugium is feed into the baffles "M". This then reduces the bubbles but not anything beneficial.

OK, good suggestion.

Here's the revision...

That looks better to me. I'm definately not a plumbing expert though!!! I'm plumbing my tank right now too, and I'm going with a Herbie silent overflow, you should check out the design. The way you have B & C set up it's going to a very noisy overflow.

I'm pretty sure sulphur denitrators need to work continuously. I think they take time to start working.

I will.

Not sulfur ones. It takes them only a few days to start working, or at least people tell me.

Yes, this is what I meant. You said you'd use it intermittently though, wouldn't it be better to run it all the time? Albeit, I don't know much about these...

Models 1260, 1262 Performance Curve
1260: Max Pump Output: 635gph, Max Delivery Head: 12`1``, Max Power: 65W
1262: Max Pump Output: 900gph, Max Delivery Head: 11`6``, Max Power: 80W

i think you are going to be dissapointed in your flow with all the conections you have tee'd off your main line. if your going to use an extra pump for your fuge maybe you could steal some of your water from the return on your fuge to fuel your reactors.

i helped a freind setup a 70 gal tank and it had a 900gal return pump i believe, and after all was said and done i felt it was not enough flow granted it was a ocean runner pump not an eheim.

There's an Eheim 1262 in the tank as well, hooked up to a PVC manifold on the bottom. I also removed the tee-off from the mainline. That should bring my turnover to about 14X the tank volume per hour... I think.
