Lanthanum Chloride in Kalkwasser

[Alexander1312]

I dose 400 ml of Kalkwasser daily over 12 hours from a one-gallon jar. Also, I am planning to restart dosing a highly diluted solution of Phosban L / Lanthanum chloride to bring my phosphate down, which climbed up again to 0.22 ppm (Nitrate 2.3 ppm). My question is, could I combine the two, and add lanthanum chloride into my Kalkwasser? The LC solution I will be dosing will bring my phosphate down over 4 days by 0.08 ppm. Thank you!

I can't speak to whether or not the two will react chemically, but I can't imagine this would work due to the fact that whatever you are dripping into to catch and filter out the lanthanum phosphate flocculate (like a ~10 micron sock) will very quickly become clogged by the kalkwasser slurry.

It won’t work. The lanthanum will precipitate as lanthanum carbonate. :)
