I see what ponddigger has been saying now about ponds and waterfalls ,that are not done right .They put rocks around the pond and around the water fall but never add rocks into the landscape part of the pond .Mine is far from natural but I saw one this morning that a neighbor just did .He has rocks he has plants in and around the rocks but it just does not look right.The rocks look placed and not like mother nature intended .I did mention it as we were talking and that is when he realized why he could not figure out what was wrong with the pond.He told me he wanted it to look natural and that is when he realized it did not look natural .He asked me for help so he got my honest opinion .He was up here to ask me where to get fish and since the pond is brand new as of a couple of days ago ,I told him he should wait and how long and what he needed to buy next .Now he is moving rocks and ordering some bigger rocks to put around the area .He also wanted my help in building a bridge over his stream ,he of course mentioned that last .He did do a great job and he admitted that he did come up to my house to look at my pond and my filters .He said no one answered the door so he took a look .
