[Resolved] Heater for AutoPot 25 Gallon FlexiTank Pro To Parent Forum April 24, 2019 at 11:18 am #139 herndongoobParticipant Is it safe to use an aquarium heater with my FlexiTank Pro? April 24, 2019 at 11:19 am #142 JoshKeymaster Hi, Yes you can use a heater but we recommend that it does not come into direct contact with the plastic on the tank, you could use some chicken wire to make a cage and suspend it in the middle of the tank. Hope this helps. Thanks, Josh You must be logged in to reply to this topic.
