I was talked out of having a skimmer by several people in favor of a bead type filter and eventually a UV filter. Today, though, at a local commercial pond place, they were horrified that I didn't have a skimmer. Of course, they sell skimmers. I really didn't like the amount of nasty green stuff in their ponds, but I'm thinking it was due to the fact that they were very shallow with lots of huge koi in them. I think that since it was a place with lots of foot traffic and employees roaming around, they don't worry about predators. Also, there is no way a fish could survive the winter in those ponds. They breed them and I'm sure they have the facilities to move them inside during the winters. Ours have lived just fine outside for 7 or 8 years, until our hard shell liner split this past winter.
Also, I noticed that they had lots of rocks in their ponds sitting on the rubber liners. I have read everywhere that it's a big no no. Maybe that could be why there was so much green crud in their ponds? In fact, we visited three different landscaping/pond equipment places and they all had rocks and/or gravel in their rubber lined ponds. And my wife and I noticed that they all had more dirty looking crud in their ponds than we liked. At the time, I just assumed it was because they had more to do running the business than cleaning ponds.
So what's the consensus? Do I HAVE to have a skimmer? I haven't seen one I really wanted or like the looks of. I've already put in the liner and filled the pond, so it would be major to put one in now, I think. And is it OK or not advisable to have rocks lying on the liner? It looks kinda nice, but I'd imagine it makes the pond harder to keep clean.
