Lanthanum will not be skimmed out, it has to be mechanically filtered out. It seems as though getting 100% of it out of a display tank setting is not possible and some people (including Randy Holmes-Farley) question what this precipitate will do over time if left in a tank. |
Not to dig up an old thread, but I recently ran into an issue where my alkalinity dropped from 8.4 to 6.4. The only difference was a couple of doses of Foz Down and the addition of a Calcium reactor (My Calcium levls stayed exactly the same). Could it be related?
