DIY Lanthanum Dosing

[PPBlimpy]

Trying to wrap my head around the numbers.
265G /1000L system with Phos at 1.15

Would be dosing LC into skimmer input via dosing head split over 24hrs with a 10 micron sock hanging off the output of the skimmer

Looking to purchase Lanthanum Chloride Heptahydrate and finding on amazon 50G for $60
@ 9G per 500ml rodi

theoretically mixing all 50G LC into a little under 3/4g (.726g or 2750ml) of a gallon of rodi per recipe on first post.

What is the shelf life of 3/4G of this mix? Can I mix it complete, ad to a dosing container and allow my dosing head to drop it into my skimmers input.

At the mix rate listed above what would be a very safe dosing rate per day?

My system is 1000L so 10x the original sample.
Dosing 10ml / day then should remove .047ppm Phos

Is 10ml / day a reasonable starting place? At this rate after 7 days I could see a reduction of .329 ppm not taking into account leaching and adding phosphates on a daily basis with feeding etc.

appreciate any guidance

I’d go off the recommendation I made in post 1 about targeting to remove 0.05 ppm per day.

Shelf life is unlimited.

OK so then yes the 10ml per day should net .047ppm daily removal.

Maybe instead of 50G I will find 25G.
275 days worth of LC mix may be unnecessary to have sitting around.
