rena xp4 micro bubbles

  • We are currently upgrading MFK. thanks! -neo
i have 2 xp4s and an xp3. sometimes when i clean it or replace new polishing pads it does. is your filter new? or did you just clean it?
 
I occasionally have that problem with my Fluval 405, but it's just after I clean it. It goes away after a few minutes. How long has it been doing it?
 
Mine has taken 24hours to mostly clear the micro bubbles. Mines the xp3, but its the same piping.
