I have no idea what any of that means. :lol:

How about an explanation for simpletons like myself?

Water levels for two return pumps will not be the same.

I say drop a baffle from each bubble trap. Over kill. More sump space.

Thanks for clearing that up! I was confused/mesmerized by all those chambers.

Speaking of chambers, I am against integrated dosing chambers :-). I frequently clean the crud out of my jugs by rinsing them in the sink. Can't imagine what a pain it would be to try and clean out integrated ones in your sump. I suppose you could just live with any residue and not bother to clean them.

What about incorporating your heater(s) into one of the bubble traps to save space

Mine are in a wasted bubble trap, are always wet no matter what the return pump is doing, and are not fully submerged so hopefully they'll last longer (not fill up with water over time)

Same idea as what you are planning;
Drain to whatever chamber that overflows through the socks, then have the heaters in the next (upflow) chamber and voila, heaters are always wet, easy to remove and keeps the tops dry

Hopefully your sump is deep enough for your heaters to stand up straight :wink:

Well it looks really fancy. On the first drawing the baffle heights look good. I've found you need to have the socks about 2" above the water or they tend to shift out of there holder. On your second drawing Your sharpie lines show the water being about the same height as the sock holder. From my experience (what little there is) I think that you will find your water height will be too high in the middle chamber even with clean socks as you need to have a slight difference in pressure for the water to push through the sock. The other thing is you want to have the safety channel. If your socks plug up you want to have a way for the water to go over the baffle. Right now it would hit the floor. Not that 8 socks are going to plug quickly. Only other question I had was is there a specific reason for running 2 systems back to back like that? I have 2500gph running through 2 4" socks and the water still splashes into them making me think they can handle even more flow. Couple of 7" socks and you could run the whole amount through them. Then you got room for a refugium or frag tank. It's an awesome size, excited to see this one get set up. If its anything like your other tanks it'll be stellar. I like the built in chambers and ato. Good use of space.

Returns go straight to tank with maybe a couple splitters so you have 4 nozzles going into tank (depending on size of display). Then make closed loop to run the 8 OM outputs.

Eight 4" filter socks? I would rather use four 7" filter socks. I hate 4" filter socks.

Looks great Greg. Is that ATO chamber going to be fed from an ro/di system or are you having to manually add water? If you are manually adding.. It's to small.

I know you have a lot of returns heading back to the display but I think I'd still rather a larger single return section with both pumps in it.

I still dont understand the purpose of the two return chambers, with a sump that size you could have a bad-ass refuge and a larger return area with both pumps in it, or even a larger ATO area. Also does that ATO top off both return sections? seems like another pump would be needed...

It a 300 gal 8'er Myka. I dont want another closed loop, also a pain in the arse. I want to be able to control the amount of flow on each pump as one pump will return on one half of the tank and the other pump the other half.
