Need higher turnover rate?

So I have a 90 gallon total water volume. I have 2 since 1200 poweheads and a 951 gph return pump. I run a manifold tho with currently a bio pellet reactor, UV sterilizer and soon to be a JBJ chiller...do u think I need a bigger return pump. Plus my tank is 2 feet tall and at the return pump tubes the water is coming ou but definitely slowly. I keep SPS pls and softies. No Arcos to or Monty. Just alien eye green birds nest, procipolla and a meteor shower as of now...
