Foam blocks in sump

[whatchamacallit]

I recently removed the foam block from my reefer 170, but now have a microbubble problem. Anyone know of any other solutions besides the foam blocks or where I can buy them to replace once a month?

Whyd u do that i just cleaned mine out today

Traps a lot of detritus and slows the flow down in the chamber which makes the water levels go crazy. Wish they sold replacement ones id buy a bunch lol

Lolol me too in my area we cant even get the red sea filter socks for like another month so i juss stuffed the cotton filter media ontop of the foam, maybe you could try that

I buy the large hagen foam filter blocks and cut them down to size.
