I been reading about dosing lanthanum for lower po4. I understand most of it in using a 10 or 5 micron bag and dosing it slowly and dont drop it more then .03ppm per day. So like I said I understand most of it. The area I have trouble with is how much to use In a 1000ml iv bag. I have read 3mls for a 1000ml bag and read others. Is the amount of lanthanum chloride used determined on the amount of water volume and amount of po4? If there isn't a set amount to use it is just something that needs to played with to find the right amount to use to drop po4 down by 3ppm per day until close to 0. And once close to 0 is achieved then finding a maintenance dose to maintain it there?

Second question. My buddy has several tanks and he wants to use lanthanum chloride. He was told to use a 10 or 5 micron bag but to just dose the 3mls right to the bag in a full dose and not drip it. Y is dripping a better method so I can explain it better by him.
