Will it help if I have certain types of stones like lime and sandstone in the pond? What would happen if I used salt water rather than regular city water to fill the pond? Please help!
First off, I applaud your intention to control algae without chemicals. It is not necessarily the easiest or most convenient fix, but most chemical solutions are only a temporary cure for the problem anyway.
There are several ways to keep algae under control in your pond without using chemicals. The key is finding which combinations of biological and physical components work best to keep your pond in balance. It may also take some time and patience to figure that out. It is not clear to me from your question whether your pond is stocked with fish, so disregard any of the following strategies that do not apply to your situation.
Also, don't be afraid to approach and compliment the successful pond owners you see. They'll probably be more than happy to share their secrets with you.
I use an algae control product in my pond that is very natural and easy to apply. It is environmentally friendly, safe on fish, pets, humans and plants. You can even swim in the pond.
Have them give you a free quote. I'm sure it will not cost much considering it is a very small pond!
Plants, Floaters and Potted
Plants will soak up all those nutrients floating in the water that the algae also use to grow. The more plants you have the less nutrients in the water and no algae.
Sterile Carp is the only way I have found to control the algae problem in my pond. They have to be special ordered. I have two in my pond. ~Janette~
I had the same problem finally I had to get a filter , (a large 55 gallon drum with pvc pipes in it with holes. You can go on line and look up how to make one. It works good but you also have to provide shade for your pond . I just got rid of my pond because my back just couldn't take the cleaning anymore. At one time I had over 100 fish a mix of kaoi and gold fish. Also remember that gold fish give off ammonia and that is a toxin if it builds up. Good luck with your pond.
Barley straw in your pond will inhibit algae growth.
I have a small fountain with a prefilter; and the "spitter" part of the fountain--an ornamental frog--has a small UV light inside that the water passes by, and it kills any algae without chemicals.
Q: I am desperately looking for a way to stop algae from growing in my small pond with goldfish in it. It is a container pond and I have tried everything. Does anyone have any home remedies?
Thanks in advance,
Algae multiply rapidly under the right environmental conditions-especially in water containing excess nutrients (phosphate and nitrate) while having access to a lot of sunlight promoting photosynthesis. Effective control requires depriving algae of food and/or light.
Here are a few natural ways to control algae:
Don't overstock your pond with fish. Decomposing organic waste from fish provides a continuous supply of nutrients for algae bloom and string algae. Keep your pond clean by regularly vacuuming the bottom to prevent build up of these nutrients along with frequent partial water changes.
Shade can be supplied with plants such as water lilies and water hyacinth. However, because the pond's primary source of oxygen is at the water's surface, too many surface covering plants can result in low oxygen levels (signaled by gasping fish). You'll need to provide additional aeration and/or reduce the number of fish in your pond if you want to maintain extensive surface-covering plants.
Consider shading the pond's surface with a type of canopy made from shade cloth or lattice. Many aquatic gardeners find this inhibits growth of algae while protecting flowering aquatic plants from excessive sunlight and heat. This method will also protect your koi's colors and protect them from overhead predators.
If all fails, there are a number of algae controlling additives available that are safe for fish and aquatic plants.
