Also, your rocks filling up with phosphates is directly proportional to the amount of poo you have in your tank. If you are siphoning out the poo and have good flow on your rocks, they will not fill up. The surface bacteria on the live rock break off the top layer of rock in order to free up the phosphates the rock traps. When the bacteria dies or poops, the phosphate is offloaded in what's called bacterial flock. If the rock has good flow around it, the flock will be lifted away from the surface and it will settle on the floor of the tank where it can be siphoned or left to stew. Nature, in its own way, ensures the rock doesn't become over saturated with phosphates if it is cared for properly

you cant say its Flawed if your saying that everything in this hobby is flawed what works for 1 may not work for another , and for Phoshate you put phosphate in everytime you feed the more you feed the more phosphate it get in a lot of ways, yeh in nature were the water is changing every second why are we doing this anyway everyones tank is deferent my sand bed has never been messed with in almost 9 years and my tank is STUFFED what works for me might not work for others its part of the hobby everyone does deferent ways ??
