Another flow post

[Max93]

I currently have in my waterbox 220:

two mp60s
2 op4s

I run them nearly at 100% and I feel that I don’t have enough flow.
I mean, all the polyps are moving but they look like they want more .

maybe it’s just my placement?

mp60 middle left
Mp60 middle right
Op4 back right corner aiming towards center of tank
Op4 back left corner aiming towards center of tank.

I do notice a major difference in power after the pumps get a citric acid bath. But what am I supposed to do, clean them weekly?

all is happy and growing but man I really think more crossflow is needed here. I was thinking of adding two Nero AIs on the back of the tank facing forward to provide that extra cross flow.

I don’t know, I’ve been chasing flow lately ever since I got all my trace and big 3 perfectly stable. I’m not planning on buying any more pumps for a while but wanted to see what others do that have massively stocked acro tanks.
Thanks for the discussion

If you plan to add more powerheads I'd stick with Vortechs (bit more expensive, but they're superior to the Nero and you'll have more flexibility with being able to swap-in wet side heads).
