Alright coop folks im upgrading from a well established flex 15 to a flex 32.5 and I dont really have a way of having them both set up so I think I'm going to do a straight swap and treat it like a 50 percent change but transfer everything mechanical filtration c nodes gravel plants and all The part that worries me is my blue phantom pleco im not sure how he will handle the transfer especially since last time I tried to catch him he jumped straight out of the tank and about 4 feet across the room... Any advice. I know ideally it would be best to set up the 32 in advance and use part of my media to cycle it but its simply not possible
