Jebao pp-4 and return pump ?

[Tylerc33]

Hey guys I have 2 of these for my 75 gallon. Do you think that’s enough? Or should I consider upgrading to something else? It seems like it’s a really light flow. Also any recommendations on what settings to put them on and where to set them? I have them on the back glass right now one on each side of it.
Also looking to upgrade my return pump any recommendations?

2 pp4’s are only really suitable for probably 25-30 gallons max, a couple rw-20‘s or similar would work better.
