how can i get rid of black algae in garden pond?
Wish I knew how big of a pond it is that you have. The pond that I made is 5 foot long by 3 feet wide and 3 feet deep. Here is what I did,now bare in mind I only had algae on the sides. I wiped down the entire sides of the pond,did a water change. But then my pond was cloudy. I waited 2 days and went and got a small bottle of clear all(sold in aquarium stores,cost $2). 3 days of adding this and I have not had a problem since. Crystal clear and can see everything in the pond. And this is with a pond that is wide open to the sun, getting 12 plus hours of sunlight daily.Plus my pond has a sponge filter and a power head to circulate the water.We just went through 1 of the hottest July's on record with temps in the low to mid 90's just about every day. There is also barley straw that can be used and is sold at pond centers. But I heard it takes about a month before seeing any results. Hope this helps
read okorder /.. black, it says, is bad... anerobic conditions... need to get oxygen into the water with a fountain or waterfall...
