Hello everyone.
New here and total beginner in saltwater.
I have a five month old 22.4g AIO cube.
Kessil a360xe
Red Sea Nano Mat
Ai Axis 40 pump (400gph) with dual random flow nozzles. Set to 67% at the moment.
Ai Nero 3 (up to 2,000gph) (set to wave 55% for 3 seconds then 1 second off or some minimum strength).
Hygger mini wavemaker (1600gph). Set to random flow. Random strengths and times.

Tank stabilized pretty instantly thanks to TBS live rock and sand.

I love those very lush, full looking colorful reefs. So over time I added a bunch of zoas, 3 torches and quite a few SPS (purple stylo, bird's nest, bubblegum digitata, branching montipora, green slimer, strawberry shortcake, pikachu, green anacropora, garf bonsai)

All the sps are on two large rocks which are leaning all the way agains the back wall.

Water parameters are in check, no issues there. Water is clear, filtration good.
The only thing I am very unsure about is the flow. I only know it's good enough for the three torches, they sway really nicely. Zoas are also thriving.
But I have no idea if my sps are getting what they need and where they need it. Nor do I have experience to judge theflow by the looks and polyp behavior.

I have a feeling that my rocks positions and the fact that they raise quite a bit from left to right is what makes it more challenging to provide perfect flow to all.
Seems like some are being blasted while others don't get enough.

Can anyone help me?

1. Would a gyre be good for this cube?

2. I saw some corner 45 degree mounts for nero. Would those help? And then directing it from either back or front corners? Maybe add second nero and aim them from both corners to shoot at both rocks?

3. How do I even know flow is good? I feel like it's something you need to have the feel for, which, as a beginner, I definitely do not have.

Thank you for any help and advice!

Flow is the hardest thing to get right IMO, especially when you have lps and sps together. I struggle with it all the time.

Add a trachy in there and you'll really give yourself a challenge getting the flow right lol

Tank looks nice. Maybe just keep doing what your doing? A mixed reef is tough getting flow to make everything happy. I ended up starting a seperate tank for SPS. Many like acros are hard to give too much flow as long as it's random. I imagine one could blow the flesh off a torch with SPS type flow. I was running 6 powerheads in my 36x24x24" SPS tank until I switched to orcas.
