Is your backyard pond turning green? It is so frustrating when you try everything under the sun to fix it but you still end up with green water after a several days? And adding all the filters in the world will still end up with green water. The only way to treat it is to understand the cause of green water and then use the right tools to deal with it. That process to get clear and clean pond water begins with understanding something as small as single-cell algae.
What Causes Green Water In A Pond?
Most algae are single-cell photosynthetic creatures, which means they don’t classify as plants, animal, or fungi. They are among the earliest forms of life on this planet. Algae is the main cause of green water in a pond. This tiny, microscopic organism is the main reason why your pond water is turning green. So the more algae in the water, the greener the water gets. You also need to know that not all algae is green. some algae is brown, amber, red, and orange. So you might not end up with a green pond but one with a dirty brown or red color.
You Cannot Filter Out Algae
Going back many years ago, before the start of the Internet, fish and pond hobbyists didn’t understand why their ponds were green as pond aerator pump didn’t exist back then. So they tried to filter out the garbage, algae and weed in their pond, hoping this would make the water cleaner. No amount of regular pond filters will keep algae out. So because most algae are single-cell organisms, which means they’re too small for a filter to scoop up. You can’t kill the algae either because chemicals will harm the good bacteria in the water. Those chemicals could also kill plants and fish you have in there too. The best way to get rid of algae is to starve it from nutrients and to make the water a less optimal choice for them to reproduce. That process starts with aerating your pond.
Proper Pond Cleaning
Of course, none of this will work without proper cleaning. First you need to transfer your fish out of the pond and into a large tank for a few hours and give the pond a good clean out. Remove all the mud, muck, and decayed material at the bottom of the pond. Once everything is removed, you can apply a few chemicals to get everything washed and balanced. Now put water back into the pond, treat it with some chlorine remover and let the water return to its natural chemical composition in a few hours. When the chlorine is gone and the water is clear of all chemicals and imbalances, put the water and fish back in. Turn on your pond aeration equipment and other tools like water filters and a lake fountain to keep algae from growing. You can also add floating pretty plants to help clean the pond. These floating pads will infuse oxygen back into the water and help reduce carbon dioxide, again another tool in preventing algae from overgrowing in population.
