Where to place SLW-30 wave pumps

[NormanB]

I realize that now 2 DT's are the same, however I'd like some opinions as to where to place 2 of these in my reef.

The DT is a standard 75g Marineland RR and the overflow is on the back left side and with approx. 75# of live rock. The substrate is 80# of Caribsea Fiji Pink. It's much finer than expected so, a wave pump can not be placed low in the tank or even set too high speed wise.

Currently, I have a SLW-30 on each side glass pointing towards the middle. The right side is about mid panel and about 7" down from the waterline. #2 is on the left side positioned about the same, or maybe a bit more toward the front than the right side.

Other circulation is from the return from the sump. The pump is a Current USA eflux 6010 set at 75%, so based on the documents I'd say the return flow is approx. 800-1000gph.

For livestock it's mostly a FOWLR and a few zoas.

So, what do you guys and gals think?

If you need more info, please let me know.

Thanks so much.

I have 2 SLW-20M on a 29g. I found out that the flow from them is extremely directional (use an airline and you should be able to determine it as well). Now I use them as opposing gyre pumps. They switch on and off every 6 hours changing the direction of flow. (My rock scape is meh and I plan to do something about it. Haha).

I got the idea from this video.
