Well now that I am living at my mom's I figure I can manage her small pond better (she tends to let it go). I installed this pond years ago and didn't do a great job but it works for my mom's needs (sound of water). A coupe of years ago one of her neighbors gave her some feeder goldfish. Today I did a small water change on the pond and filled it back up. Hoping to keep on it and clean it up well. I think the first thing I am going to do is build a better net for over the pond. Any other ideas on how to improve the pond (mainly keeping it clean)?
