Adjustable return pump for 50gal AIO?

[One Reefing Boi]

I have a Waterbox 50.3 AIO and looking to upgrade my return. It’s a pain to adjust by pulling it out and then adjusting the hard knob. Are there any good manufacturers who make a controller adjustable return that will work for a 50gal AIO? And will fit?

Aqua Illumination Axis Series... Probably would recommend the 40.
Hyggr dc1500

The axis 90 has a diameter of a little shy 3 inches... how big of a space you have back there?

According to their site it is

11.8"×4.7"×17.7" (LWH)

But I’m not sure if that’s the full with at the top or not because the bottom is a bit narrower because of a bubble trap wall setup

If you have 4.7 inched thats more then enough room for a axis 90, or the dc2500.

Id probably get one of those two.

Thanks, I’ll do some research and see if either makes sense
