Nice looking sump! Do you have some sort of pre-filter before the tank water goes into the moving bed filter? Also, how big is that tank (length and width)? I have a 90g sump with k1 and bio blocks but I feel like It's pretty crammed in there. You're looks a lot more spacious.

Ill post some more pictures. The water goes through a fine filter floss that removes most of the fine stuff. Before going into the k1 chamber. After it passe the k1 it goes through the heater section. And then through more fine padding. Before going into the ceramic media. Water stays pretty clean. The sump is 60x18x20
