It looks like there are a lot of people that are new to ponds like me. I have had the pond for about 9 months. About 2 months ago I added some goldfish. I wanted to try them before I bought any koi. The goldfish are doing fine. I haven't fed them at all, but I don't know what they are eating. I got a bunch of green string algae and after searching on the internet, I added some chemicals which didn't hurt the fish, but didn't completely clear up the algae. Besides the small amount of growing algae, there is a lot of dead (I think) algae on the rocks. I also purchased a water test kit. All of the tests were OK except the ph. It was at 8.0 I bought some ph down and have been adding it, but the ph is not changing at all. I am totally confused and I don't really want to add any more chemicals that don't seem to do anything. I worry about the goldfish, but they seem to be doing great. They have tripled in size since I got them. One other problem I have is tadpoles (and frogs). They are getting big and will be frogs soon. Do any of the experienced people have any suggestions for me.
