heres a copy of what i posted in another thread:

After reading a bunch of the lanthanum chloride post I got the Seaklear phosphate reducer and a 10 micron sock a couple weeks ago. Yesterday I finally got up the nerve to dose the tank and WOW... that stuff works.

I mixed 2.5ml lanthanum into 1/2 gallon of RO/Di and dripped it really slow into my overflow in the tank, then It flowed into the sump through a 10 micron filter sock.

I tested this morning twice and both times the checker reads 0.00

This is in 250+ water volume

Cool,

What was your pre-lanthanum dosing phosphate value?

It's been staying between 0.08-0.10 even with the use of phosban. Im tired of of the GHA and the cost of GFO, thats the reason for the Lanthanum.

I may have to plan on a dosing regimen if my rocks and sand start leaching PO4 back into the system but I haven't tested that yet. If I do it's going to be a very small amount.

Problem with lanthan chloride going into the aquarium water.

Hello everybody.

I'm having some trouble hope you can help.

I dose lanthanum chloride into my pipe work that goes down to a clarisea sk5000 roller filter after the filter the water goes into the sump - skimmer - filters etc..

I dilute my seaklear commercial 7 ml lanthanum chloride / 1 L of water. Dose it over 24 hours distributed on 150 occasions a' 3,6 ml/dose.

I get the wanted effect in lowering phospates but it also shows on ICP testing and the amount in the water is rising. 4 ug/l last time and 11 ug/l this time.

What do you recommend? Maybe the clarisea sk5000 isnt suitable for this?

I've also noticed an increase in other of other substances like aluminium, lithium and barium do you know if the lanthanum could "free" other substances?

The above user had a 10 micron sock. Is the filter paper of the same micron or larger.
As I understand it filtering should be with a fine micron.
As far as purity I have no idea.

I don't think lanthanum chloride dosing would add elements except as impurities in the product. How much of a rise are you seeing?

The producer of the roller filter told me that it should be equal to 20 micron socks.

I don't think it would add unless the product is contaminated - I've sent ICP o the product so time will tell.

But what I ment was - could lanthanum cloride in some way contribute to the rise in some other way?

Perhaps make other substances react/release or even animals/algue etc?

It might be possible, but it seems very unlikely.
