Very high flow rate running through my sump. It consists of some live rock rubble suspended with some eggcrate.

I imagine that under the flow under eggcrate would be alot slower flow rate and top would have higher flow?

Is it loaded with sponge and fan worms

Its not a LOT slower, but for sure it is slower then the top. Lots of fan worms and tonnes of sponges.
