i was thinking about doing something nice for my mom seeing as she has a bunch of goldfish in a 55 and always wanted a pond. she has a few of those cheap pools that are in between a pop up and a regular pool and she bought one over the summer that has already broken. would it be possible to use the filters, which are much like regular pool filters as a filter for a pond? i mean you run a bunch of water through it and the chlorine would be gotten rid of right? what else would i need to do before i could use this as a filter for my moms future pond.
