Need help with flow from IceCap Gyre 4k

Shanel · May 14, 2025

When I use the reverse function on the Hydros pump, the flow is directed toward the top of the rockwork. I know rotating the pump housing can shift the flow direction, but I prefer having the flow angled more toward the surface.

Is there a pump cover available that allows custom adjustment of flow direction in both forward and reverse modes? Or at least something to baffle the flow, so it doesn’t blast the corals and damage their tissue?

you can always try ziptying filter floss too it. It should lower the power.

I found 2 different directors, both 3d printed. I still am unable to find a file to download so I can print a set and see if I can start using reverse on my pumps. I was able to find a file for Maxpect Gyre XF250 and jebao cp40 but I don't think those would fit. 3d printing is still new to me. I just got one so looking for a project to learn on.

Do you have any dimensions of these?
