Subject: phosphorus and phosphorus control (4)


Tests with a simple model of phosphorus states in aquariums show that
reducing feeding rates is the most effective means of reducing phosphate
concentrations.  The second most effective ploy is to encourage higher
rates of phosphate precipitation or sorption and the third most effective
ploy is to increase water changes.

Here it is the familiar diagram again, this time for the last 

I find this fascinating Roger, I would like to throw in another factor: 
plant mass. What role does the plant mass, the amount of plants in the tank 
play? Is a heavily planted tank more apt to lower levels, or make them 
higher? We all know that whatever goes into a plant must come out from 
decaying leaves and stems. For those of us who tend to plant as thick as a 
jungle, just keeping the tank clear of debris can be a challenge. Does too 
many plants in a tank make the problem worse? On the otherhand many people 
also have sparesely planted tanks, or tanks with only very slow growing, 
low light plants. How does that factor into the equation?
