What are bioligical products needed for?

Biological products help to break down build up on your ponds bottom. This might include leaves, branches, dead plants and even dead fish to name a few things. These items will foster algae growth if left alone. The algae will use that as a food source and be much harder to control.

The best way to control this build up is maintaning the level of bacteria in your pond. Adding biological products is a great way to increase the amount of bacteria. It is also a natural way to help control algae growth.

This type of product is most effective in colder water but can and should be used during normal months that require care which differ depending on your location. The best times to add this product are spring and fall when the water is to cold for use of copper based products. This normally is the same times when there is the most build up in the bottom of the pond. It is also important to know that using copper sulfate to kill algae also kills these beneficial bacteria. So another good time is a couple days after treating the pond with copper sulfate.

What brand and product type should I use?

Determining this can have many different variables, such as price, size of your pond, product availability and more. There is not a perfect answer. However, in most cases it's getting the one you are happy with. For instance pond dye is available in many different brands. It can be found at different conncentration levels. Lastly it can be found in liquid and water soluble forms as well.

In the end you will have to decide what you like and want to use. Always make sure to check the labels on the products though for rate of usage. Just because two dyes are both in one gallon jugs does not mean they have the same coverage area.

You will normally pay a premium for water soluable packs. Larger quantities will generally be less expensive. Cheaper is not always better and likewise more expensive is not always better either!
