Algae in excessive amounts can be detrimental to your pond’s health – to the marine life residing in your pond and to the environment surrounding it. While algae control can easily be handled with chemicals, it isn’t necessarily the best solution. The best solution would always be go as natural as possible so as not to upset the eco-balance in the environment. And as saying goes, “An ounce of prevention is worth a pound of cure,” it will always be better to take care of algae growth before it becomes a problem. We have listed five natural ways to prevent excessive algae growth below:
While algae are a normal occurrence in ponds and lakes, there are ways to prevent it from getting out of control or reproducing in large amounts. Here are some tips:
1. Use algae-eating aquatic animals.
Nature has provided lots of ways to make sure our ecosystem remains balanced. There are aquatic animals that eat algae while leaving aquatic plants alone. There are algae-eating shrimps known as Caridina multidentata, algae-eating snails called Nerites that are great for eating algae from smooth rocks and algae-eating fish like the loriacariid catfish famously known as suckermouths or plecs. You can also use live bearing fish like mollies.
2. Make strategic use of plants.
Algae need the sun to be able to feed and grow. You can use floating plants to block some of your pond’s light source so it can starve of nutrients and discourage algae growth. Well-placed plants at the bottom of your pond will also help keep your nitrate and phosphate water levels low.
3. Have pond fountains.
A key to ensure that oxygen is continuously introduced in your pond water is to have flowing water go through it. A fountain will help ensure oxygen is introduced to the water continuously, which aids the ability of the pond to break down organic matter more quickly.
4. Have physical barriers around your pond.
Fertilizer run-offs are a common cause of encouraging excessive algae growth. By installing physical barriers around your pond, you are securing your water from receiving fertilizers that can leech off from the ground.
5. Use LLMO
Beneficial bacteria help decompose sludge that can contribute to excessive nutrients in the water encouraging algae growth. It also helps improve water quality by decreasing the pathogenic or bad bacteria and increasing dissolved oxygen in the pond water.
