One pound of phosphorus can support 500 pounds of algae or more. And the more phosphorus you have built up in your system, the more likely you're going to have nuisance types of algae, and a lot of algae on your hands.

Phosphorus is commonly the limiting nutrient for algal growth in freshwater systems. One pound of phosphorus can support 500 pounds of algae or more. And the more phosphorus you have built up in your system, the more likely you're going to have nuisance types of algae, and a lot of algae on your hands.
There are a lot of different sources of phosphorus, such as run-off from agricultural fields, golf courses, or even home lawns. There's phosphorus that comes from the atmosphere when it rains. Wildlife is also a big contributor of phosphorus. One goose can poop up to 92 times per day!
The problem is, phosphorus will build up in aquatic systems. You can often see a pool of phosphorus built up in the sediments. It looks like organic muck on the bottom of your lake or pond. This can be accumulation of phosphorus from many different sources, like leaves and grass clippings, that build up in your pond through time.
It’s a similar situation with diatoms. Diatoms like a higher silica to phosphorus ratio. So again, keeping those phosphorus levels low may give those better algae a foothold in the system and be able to outcompete some of the nuisance, noxious, and smelly types that you don't want in there.
In summary, the strategic removal of phosphorus supports the fishery from the bottom up. It allows the better types of algae to thrive and get those nutrients into the big bass that you want in your system. As always, stay tuned to future episodes to learn more.
