Thoughts about Live Rock in Sump

[Red Coral Aquariums]

I have through experience as of late preferred to have no LR in the sump. I find that you collect a huge amount of detritus and sediment under your LR. With the benefits of the LR and the detriment of the collected sediment; what is your overall gain? I find that leaving an open area for sediment to settle in your sump you can easily siphon it out with a + side on the nutrient export. That is my opinion with no real proof that sediment is releasing more nutrient than your LR bacteria is consuming. In your display your use of powerheads is to push the sediment to your sump. You need to get that sediment out of your system and it is much easier to collect in the sump.
