I like it, but seems overly complicated. I just dose into my sump.

That is an excellent point. I guess the changes in chloride levels are low enough that my regular water changes should make up for it.The precipitate is LaPO4.
This means you are changing your chloride level in your aquarium and will need to water change it back to balance. Just FYI.

I am no chemist by any means but we started with lanthanum chloride which changed to lanthanum phosphate, leaving chloride ions in the water. These chloride ions might bond to something else but I don’t know. I don’t have the full chemical reactions.Enlighten me, what is a chloride level?
Depends on how much for how long. Easily remedied with regular decent sized water changes.Oops, yes I should have specified LaPO4 as the precipitate. As for altering the chloride level, I agree that this will be a side effect, I am just not sure how significant it will be? We are typically dealing with fractions of 1 ppm for phosphate and the alteration to the chloride level will be (I expect) equally small. I will have to put this question to Randy and see if it is worth worrying about or ends up being a rounding error.

They don't. Just remember the largest pools of ions in salt water are sodium and chloride. That is why they are chosen when dosing because they are so large it is harder to move them. Just be warned if they do move by signifcants amount they are not fun to get back in line.I am no chemist by any means but we started with lanthanum chloride which changed to lanthanum phosphate, leaving chloride ions in the water.

1 thing, is the brass valve in contact with salt water? I believe you can leach copper into the water
I like it, but seems overly complicated. I just dose into my sump.
I have been dosing LC everyday for the last 18 days. My average daily dose is enough to remove .1ppm phosphate in 200g. My phosphate was .23 when I slowly started dosing. I havea ton of rock that are leaching. I actually dose into a CPR overflow box that is draining into the sump. I dont collect the precipitate into a sock. There are 2 skimmers in the sump and I have not really noticed any difference in the skim. I have not noticed any cloudiness and all livestock appears to be thriving. I do have 2 yellow tangs. If the consensus is that I need to be running a sock, I will. Is there a concern that the LC will stick to pumps and such? Also as I understand, LC is great when phosphate is high but is less effective when phosphate is lower?I am curious, when you dose into your sump, do you collect the precipate? If you don't, have you noticed any negative side effects? Any problems with tangs?

It is a precipitate so it will be floating around your tank if you stir it up. Moleculare weight of Lanthium Phosphate is 236.901 g/mol vs. Calcium Carbonate 100.0869 g/mol. So it is slightly heavier than your sand of a similar particle size but because the precipitate is fine it can easily be stirred up. I am not sure if the Lanthium will interact with the free calcium once it is bond with phosphate, but I don't think it will I think it will work similarly to Calcium Phosphate and stay bond in your substrate.The one question that has been digging at me is: If I stop dosing LC for a while and fire up the reactor with GFO or Phosguard, will the Lantanum Phosphate that is probably in my reef bond to the media in the same way free phosphate would?
But will the lanthanum phosphate bond in the gfo reactor?It is a precipitate so it will be floating around your tank if you stir it up.

I don't think so. I think once it is bound into the lanthium there it will stay until you export it out. Unless of course there is an area of low PH that could re-release it. That wouldn't necessarily be good because now you have lanthium in your tank. Maybe to bind to more phosphate or maybe to bind to carbonate, depending on the conditions.But will the lanthanum phosphate bond in the gfo reactor?
