My XP4 motor took a dump on me last week so in the mean time between time I'm using an xp3 motor on the filter. I was wondering if anyone has done this before and is there any danger of damaging the xp3 motor and my xp4 rena filter while I wait?
toss an extra hob on filled with filter floss or polyester batting. that'll help 'crisp' the tank up. or if you don't have any spare filters laying around, put a layer of poly batting in the top tray of your rena.
