Hey I've never owned the pond, but I've seen some AWESOME looking ponds and I was thinking about getting an indoor one over the summer. I've seen some people using pools as ponds and I have a few questions. are those pools people use for ponds expensive? Like how much for a decent one? and can you just use a pool filter or do you need some special type of filter? And last but not least this is a really stupid one but if you had a pond like the one I described could you swim in it along with the fish 
Thanks.
Thanks.
