This was going to be my answer to the thread about UV lights but I decided to start a new thread.
When I first got my pond a few years ago I went to the pond store and asked for a testing kit. The owner asked why...seemed like a dumb question so I said to test my water. Again why? Now he had me because I wasn't sure what to say except to make sure that my water was right. You know PH, nitrates, ammonia, nitrites etc. then he asked me once I found out that something seemed wrong what would I do about it. I wasn't sure if he was being a wise guy or really was interested. I told him I would add something or do something to make it right. After going back and forth he pointed to all the ponds he had and said that he sells test kits but never used them. He said he was in the business to sell things and would gladly take my money if I wanted to part with it. His advise was to forget what I read about water quality because it would just get me in trouble. To "fix" things I would buy more stuff then to fix what ever problem that the "more stuff" caused I would buy even more stuff. You know what he was right. I did buy the test kit and used it a couple of times. Why? Because that is what you are suppose to do. I even added "stuff", everything that was recommended for what ever problems that my test kit said I had. In the end the test kit reached the expiration date, long before the chemicals were used up. Now to keep my pond clear all I do is plug in the UV light and use sodium percarbonate to clean up the string algae. I don't swim in the pond and I have 4 healthy fish not 50 or more. What ever the water is it is. As long as I can't walk or it or smell it and can see through it then it works for me. My advise is that no matter how often or loud something is said it doesn't make it right. Turn the flame throwers on I'm ready!
