Hi all
I have a 4 chamber sump
I’ve removed all the media balls and bio media from my sump as suggested on here and now have the return chamber, protein skimmer chamber and two empty chamber. The chambers are not big enough for a roller mat but if I cut out the chamber divider on the two empty chambers I can fit a roller mat in there.
My question to you guys is, do I need more chambers or is 3 enough.
1. Inlet with roller mat
2. Protien skimmer
3. Return pump.
Is that ok or would you suggest something else.
Thanks
Trevor
