"What do we do with all of that phosphorus? If the food is completely converted into tissue mass, then there will be no excess phosphate. But much of the food that any heterotrophic organism consumes goes to provide energy, leaving a residue of CO2(carbon dioxide), phosphate, and a variety of nitrogen-containing compounds (ammonia, nitrite, nitrate), as shown above. A fish, whether it is an adult or a growing juvenile, consequently excretes almost all of the phosphorus that it takes in with its food as phosphate in its waste. Of course, overfeeding will result in more phosphate delivery than will reduced feeding levels."
Some parameters keep rising without dosing anything

Could it be related to sand or something new you’ve put in the tank recentlyHey everyone need some advice just did a water change because my alkalinity, calcium and phosphate keeps going up and the only thing that dropped was the alkalinity I did a 20 gallon change on a 125 gallon with 20g sump not sure actual total water volume because of displacement from rocks and sand. Should I do a larger water change? Phosphate kept rising so I got a media reactor with some pellets but its still rising. Ha ve a bunch of lps and some sps frags shouldn't the calcium be dropping?
