CO2 injection into a Rena Filstar filter
I got a Rena Filstar XP1 for xmas for my 29 gallon planted tank. I would
like to inject my DIY CO2 into the filter so the impeller breaks up the
bubbles. is there any way i can rig this filter to do this? I used to have a
small powerhead that i bubbled into and it worked really well.
Any suggestions?
thanx,
Matt
