MH is better..... Led is getting there though...


I don't use filter sock and my sump is filthy, I hate it... But then I hated dealing with socks when I did run them.

eitherway my sump from left to right is:

1. LR rubble
2. Bubble trap
3.poly filter with more rubble under neath
4. Last chamber with skimmer, return, uv pump, and reactor pump.

like I said I hated dealing with socks. I hope to soon add a plate with poly filter to cleanse the water before hitting the first chamber..... My sump is filthy and I know it's not good for all that junk to be sitting on the bottom of the first chamber..... But that's the way it's been for 2 years with little to no issues.....
