I always like this video when people talk about lananthum. Big tank full of coral and tangs and doses straight into the water causing lots of cloudiness. No issueZ

I am currently dosing LaCL and have noticed a white film forming on my glass. I just used the razor blade and it’s only slightly coming off if I really lean into it.I run LaCl into a 5 micron filter sock in the overflow box, fed by a small dedicated pump. The sock still blocks up quite a bit, and quickly, and when it does a white film starts forming on my display glass, which can only be removed with a magic eraser. This is the most annoying part for me, the tangs seem ok for now (regal tang, YT, bristletooth), but if sock overflows it goes through a filter roller, over an ATS, pass the skimmer and through the entire sump before going into the display again, so maybe that helps. Works amazingly well though, dropped my phosphate from 8(ICP result, don't ask how much neglect there has to be to get there, let's just say our third child was born around that time) down to 0.04 over the course of a few months once all the phos have finished leeching out of the aragonite and LR, also run GFO for the last bit, seems lacl bottomed the phos at around 0.12, GFO seems to do the rest. It is a bit of a cheaper route than GFO too (or more bang for buck even if you regenerate the GFO with sodium hydroxide), well here where I stay anyway, costs around $100 for about 2 or 3 years' supply of the crystals from a glass manufacturing place. Mixes it at 5gram/liter, dose around 200ml on a 100 gallon tank per day. I have around 35 fish in there, and feed very heavily. On a lightly stocked tank GFO is probably a better bet, and less effort to make sure the filter socks stay clean.
Where are you dosing? All the precipitate should be captured by a filter sock and skimmer.I am currently dosing LaCL and have noticed a white film forming on my glass. I just used the razor blade and it’s only slightly coming off if I really lean into it.
Can you tell me more about this, and how to remedy? A magic eraser? Did you have to drain your tank to do this?
I am finally getting my PO4 in check and now my display is hazy white, so frustrating, but glad I see a reason from your post, as I was otherwise still searching…
I like your application and use of a reactor. Can you post a pic of how you get the drip in there/the setup? Thanks!In the past, I have dosed too much, too fast and watched my wrasses hyperventilate for a few hours. It can be dangerous if done haphazardly.
Since then, I’ve dosing lanthanum daily into a reactor and it has been life changing. I use a Kamoer doser and spread it over 24 daily doses directly (through a tee) into a standard reactor with a pleated filter. It keeps my phosphate right where I want it.
@Randy Holmes-Farley where would one acquire the lanthanum you use in your recipe? I currently use Seaklear but I wonder if there’s a cheaper option as I dose ~5ml/day
I was dosing into a 5micron sock that would clog from algae, etc within a day, then I read a few having success by dripping into the body of the skimmer.Where are you dosing? All the precipitate should be captured by a filter sock and skimmer.
Good to know. Are you doing this constantly, or just as needed?I have no issue dosing into my skimmer with no white film on my glass but I run my daily dose over a week. So very low dose per day
I tried a million ways of dosing this because of my very sensitive sailfin tang.I have no issue dosing into my skimmer with no white film on my glass but I run my daily dose over a week. So very low dose per day
Wait until you see what's in your pumps, powerheads, etc., etc. I'll never use it again.I am currently dosing LaCL and have noticed a white film forming on my glass. I just used the razor blade and it’s only slightly coming off if I really lean into it.

That may indeed, be so, because I went too heavy and fast with LAN but when I stopped, I recall having to do a complete cleaning of my sump and everything in it and had never seen such a mess-or that kind of mess-before.You found precipitation on pumps?
I’ve not seen folks report that, and while I am not claiming it isn’t lanthanum of some sort, decreased phosphate will likely increase the tendency for calcium carbonate precipitation.

What is the source of your Lanthanum Chloride?I was dosing into a 5micron sock that would clog from algae, etc within a day, then I read a few having success by dripping into the body of the skimmer.
I have been doing this now for 3 days…
Using the SeaCleer pool version, diluted...What is the source of your Lanthanum Chloride?
I haven't seen any effect like that in my tank, but I use reagent grade from a chemical supplier...
Before that I used Blue Life Phosphate RX for a long time, also with no issues.
Wow, thanks for the tip on the razorblade scraper from amazon. I had to use the small flat blades from hardware store, they work but dull quickly and had to really put pressure on them to carve off the white build up...I've had the same problem and it drove me crazy. It took me a while to figure out that Lanth was the cause, as my first thought was carbonate precipitation due some mistake in the two part mixture.
As you noticed, the film is very stubborn and for a while I thought it was beyond repair, but I managed to get rid with it with a razor blade. I got these scrapers from Amazon that use generic razor blades for shaving.
I also tried brand new blades on the Tunze magnet cleaner and it helped a bit, but nothing closer to the razor blade. I've also tried the sharp blades from the hardware store and that not didn't work, but also made some deep scratches.
I haven't tried a magic cleaner, but 20y ago I damaged the front glass of a brand new tank with a scourer and that was enough to never get a sponge near the glass ever again.
