Hey Skimerhiperer, thanks for the comments (I am a bit of a noob).
Sump: Thought the water level seemed fine when I made the sump. Came across a lot of 14" high sheets of plexiglas, so thats what I used to make the baffles. There is plenty of room in the sump for more water, if I were to shut the return pump off, the sump would fill and still have room for another 10-15 gallons after the siphon broke from the return pump.
2 overflow boxes: Same reason I have 2 drains on my fuge (even though it is only using one). I put it in for flood insurance, incase 1 clogs. Actually ended up using a herbie style drain on the DT tank, so it is actually utilizing the back up drain to a small extent, since I've backed up the primary so there is no air in the system.
Return pump: I am using an eheim 1262 for my return pump and love it.
As for powerheads, I currently have them aimed towards each other, and also each intersecting water returning from the sump to give a turbulance effect. I've read a bit online about flow, and it seemed a turbulance like this was the best way to go until I get a more advanced system. (ie, not good to have a current constantly going in just one direction.) So, all my water collides. I use a big xenia I have to analyze the currents, and it seems pretty turbulant now.
I just hooked up an apex aquacontroller and was going to add in more powerheads to have an alternating current. Was going to pick up some korelia's at blue sierra, but had a thread here and realized the really aren't made to be turned off and on a lot, and I shoudl save up for tunze pumps, which are a bit too much for me to get right now.
So, leaving it turbulent for the time being until maybe my birthday where I'll get a few controllable heads.
Gotta run to work, but when I get there, I will look into this gyre configuration. I just added a lot of new rock and did some aquascaping yesterday, so the current probably needs some more work.
Thanks a lot for looking through my pics and telling me what you think. If there is anything else you see that looks off, i'd love to hear it. gotta run
