Opinions on my sump setup please
 

Just want to get opinions on my sump setup and what people recommend. Starts off with the drain going into two filter socks than going into the skimmer chamber than I have an 8X8 marine pure block in the fuge chamber for passive filtration than I filled my bubble catcher with marine pure balls for active filtration than my return section which has a Gfo and carbon reactor. I'm thinking of putting a bio pellet reactor in the fuge section as well and than getting a uv light. This is just a fowlr setup for now as I don't have time for a reef tank yet but will definitely get there. Am I heading down the right path??

Can't see enough as your pic is dark
Speaking as one who is now working on a 2nd sump build, I'll say;
Try to maximize your space while keeping it simple.
Having removable socks that aren't obstructed by hardware will keep you happy to perform regular maintenance.
Keep access to your skimmer and reactors open for the same reasons.
Can't say much about the new blocks you are using, but have read good things about them

The deeper my return section is, the quieter my pump becomes

If you are using the refugium as a refugium, I wouldn't put the block in there. If you're just using it as another chamber, no problem.

I tried to upload more pics but would only let me do one pic. And nope not doing a fuge trying to have a clean and low maintenance system and don't need the pods or anything for my fowlr tank. I figured bio pellets would be my best choice for large bio load and a low nutrient system??

Bio-pellets or carbon dosing is fine, bio pellets are certainly less maintenance. Those blocks will work well with either method, too.
