"As I had mentioned to your husband that if the pond is still dirty I would comeback at no charge to pull out more. Your pond did have a lot of debris in it when I had started. Also if your pond has sting algae growing turn up your Iongen to 8. It will take a week or so but you should see a reduction in its growth. The filter pad should be cleaned out once a month and with the recent cleaning the filter may need to be rinsed out sooner. If you would like me to come back please let me know."
