For you guys with monster tanks. I have a 6'x6' footprint. I have a dead spot in the middle of the tank at the bottom. I have stingrays, silver aro and discus. Will the stingrays move the bottom water around enough or should I put a couple power heads to circulate that water better? What are you guys doing for movement?

I use a half dozen disks and a pair of Korilia Mag8s in a 10x4.

This is the style of diffusers I'll be switching to. I bought a few 8.5"ers to play around with but ended up sticking them in bio reactors. Need to get some more for the tank. Hard to find decent bubble disks.......

I bet a trio of those big ones in the center would bring some life to those dead spots.....

How does one determine if a certain area in a tank is a dead spot?

Do u think that 2-3200gph circulatory will create enough flow, maybe not enough flow? I want to mount them lower in the tank and point them to the middle and upwards then play with them from there. Any thoughts? Would 1600gph get the job done?
