Question
I am a 2nd grade school teacher and I would like to use a small plastic inflatable swimming pool as a "pond" in my classroom.  I'd like to have a small fountain spouting up at the center, and I guess maybe a filter...?  I have absolutely no experience with ponds.

Answer
Hi Susana,
There are a number of small pond kits you can buy at local nurseries or DIY stores like Lowe's or Home Depot that you can use in your class room that have small fountains.  These often include small filters.  It's like keeping an aquarium really.  But you should be able to find something like what you are looking for at Lowe's, Home Depot or the large nurseries that have a watergardening sideline.  I hope this helps.
