Bio Crash?? - Switch From HOB to XP3 Filter
I have an established (6 months) 26g tank. I am upgrading from a Penguinn bio wheel to a Rena XP3 filter today and have concerns about crashing my bio filter. Any suggestions or no worries?
I currently have two Rite-Size filter cartridges in the Penguinn, I was wondering if I should cut the foam off and put it in one of the baskets of the XP3 or something.
I know the XP3 is a popular filter among the ranks here. Do most of you use the spraybar or nozzle? Any suggestions on how far below the waterline I should put the spraybar, and do I aim it staight out, angled down and away from the glass or I thought I read a thread on here where some aim it back towards the glass.
My aquarium is populated with both fish and plants. I want to make sure the O2 is sufficient but not outgas my precious C02 (DIY - 2 2L Bottles)
