What's everybody have in their sump

[Empress]

Hi. I plan to change the stuff in my sump around a little bit because I have high PO4 and some cyano growing (even in the sump)!

So besides a heater, what else do you have in your sump? I need some fresh ideas.

detritus. lol...well that and my skimmer along with a 20 gal fuge with rubble and the rabble that couldn't be trusted in my DT. i.e. peppermint shrimp and emerald crab that couldn't keep their claws off my corals. I want to add some Macro Algae eventually.

Gracilaria, Chaetomorpha, big sock full of Matrix, Vertex 180i, heater, pump and return for BRS dual reactor used for GAC/GFO as needed, sensor block and fill line for my Tunze ATO system, DIY high level sensor used to turn my skimmer off, temp and pH probes from my Apex, and my return pump.

Oh, and I'm still looking for a sump monster for this system. Small rock crab, gorilla crab, maybe an overgrown emerald... Something to help break up detritus in the refugeum.

I have a bit of a mess today, that is what. Overflow weir was starting to back up so the ATO tried to compensate before I noticed it happening. So, too much water and I've still been too lazy to tidy up the wires with the new build in progress.

Edit:
Two 150w Visi-therm heaters
Deltec 1351
Aqualifter for ATO
BRS single stage reactor (carbon)
Kessil H160 over some chaeto and various caulerpa sp.
BRS pumps dosing their two part
Waveline DC6000
