Small Ponds Need Filtration Worse Than Large Ponds
In a small pond it is even more important than a large pond to have a good filtration system. Larger ponds are better equipped to handle waste and by products of fish their smaller counterparts. This is due to the fact that normally more fish occupy a smaller space than what is commonly found in nature or big ponds. Due to this, more stress is placed on the environment to dispose of this waste before it can compromise the water quality. This is where pond filters come in. To assist in the removal and processing of excess waste, small ponds rely on filters. Filters come in all shapes and sizes. The type of filter most times will be dependent upon the size of the pond. Some filters can be placed within the pond and typicaly are better for very small ponds or ponds with less aquatic life. Slightly larger fish ponds ot ponds with a more dense population will probably require an external pond filter that is larger and capable of removing much more waste.
Now to make a filter work, it needs to be paired with a pond pump that will pull water from the pond and force it through the filter where it can be cleaned and discharged back into the pond. Again depending on the size of the filter or pond, different size pumps can be chosen. If it is a small garden pond, a submersible pond pump will work well. They are simply placed in the bottom of the pond and plugged in. For larger fish ponds and external pump will be b etter due to its ability to pump larger volumes of water with less energy consumption.
So, if you have a backyard or fish pond, but do not have a filter system, look into it. Your fish will thank you.
