Increasing flow in 20 g aio

[DaprDon]

I use a stock return pump approximately 250 gph in my JBJ 20g rimless.
Would like to replace with a Sicce 1.5 357gph rate but put a Y connect and 2 random flow generator nozzles on which actually decreases the outflow, but can create opposite random current.
Internal pumps are too strong and stationary.
Mixed reef mostly LPS, 3 yrs established.
Doable? What's your thoughts?

I'd add another WaveMaker, sounds like the return pump is sufficient

I would also add powerheads

I have a smaller aio (about 17G) and the small Jebao wavemaker works extremely well in my tank which is mostly sps and lps.
