Ponds often require treatment for common problems such as algae growth and poor fish health, so pond treatments are a great way to transform your pond back to full health. Adding a disease pond treatment will protect your fish from harmful bacteria and provide them with a healthy living environment. Excessive algae growth can cause your water to become murky, so why not treat this with green cloudy water pond treatment? Blanket weed is another cause of excessive algae growth; however, this can be treated by adding blanket weed killer to your pond.
