90 degree return fitting for tanning ledge / sun deck?

[overnight5196]

Does anyone know of a 90 degree fitting with some kind of 360 degree, spiral, or star pattern to keep the flow below the surface in an attempt to help reduce aeration?

My 7’ x 7’ tanning ledge / sun deck has a single bubbler return in the center. I’m trying to reduce aeration as much as possible. I also have a cascading water feature from an elevated spa that aerates the water while the pump is running approximately 12 hours daily but nothing I can do about that.

pH rise rate isn’t terrible. I’m just trying to lower the frequency of adding muriatic acid as much as I can.

Still working on getting to that sweet spot for TA as I’ve learned from this site it’s a factor for pH rise, but that’s for another thread.

Thanks!

Do you have automation?

I am not sure what “automation” means in this context but I do have a Pentair intelliflow VSP pump with Pentair app to control the pump schedule, if that’s what you mean. The schedule is certainly helping to keep pH rise under control. I just feel like some 90 degree jet would help reduce aeration.

If you have an automation system that changes the valves between pool and spa, then there is a possibility that you could enable spillway mode in said automation instead of running the spillover for 12hrs a day.

To your original question, if it is a standard 1.5" return fitting, maybe something l Iike this would work?

Thanks. I’ve ordered a Venturi fitting to see what that does and will try these next, pushing against the back wall, if the Venturi doesn’t work well.
