lanthanum chloride
 

while back read about this stuff but since now committed to buying a BRS reactor for GFO, thinking about it again.

Wondering if anyone here using lanthanum chloride or if did, why did you stop?

I did a one time treatment when my phosphates were .36

I think TimT who is a vendor here may be able to explain this as i am pretty sure that is what is in his phoz down product(if i am assuming correctly). I have tried a product with this in past and liked the result but am waiting for my new doser to come in before i try it again as dosing daily is a bit tedious. But when using it the only down side i found was filter socks plugging faster.

Used Seaclear Commercial Strength PO4 Remover for pools. My tank is 150G. I dosed 2.5 ml into 4l of RO water and dripped overnight into my large overflow before a 10 micron felt sock.

There is a good thread on reefcentral:

and a good article in coral magazine

Didn't sleep well that night but it took my PO4 down to .07 the next morning Then I put gfo back online. Saw no ill effects, no drop in alk and tangs breathing was normal (common side effect of overdosing or LC reaching DT). Personally would not want to use it regularly or long term.

well with un-expired reagents my PO4 is around 0.5ppm. Thinking I'll see about picking up some Foz Down if I can find locally, drip that to get my numbers down then move to GFO.

I've got a large bottle of Aqua NoPhos which is apparently the equivalent here to the SeaKlear (which I could not seem to source) and made by the same mfr. I never got brave enough to try it but I'm sure that bottle alone could keep my levels low for the rest of my life. Dirt cheap I'm just scared to try it. I've got a spare dosing channel I'm itching to use lol.

My concern is my levels are already at around the 0.04 / 0.05 level and I think at lower levels the stuff isn't as effective and will simply go through my sock and probably precipitate out in my display.

sort of what I've seen, LC good to bring down levels but then since a bit of pita other methods (gfo) for long term. A doser with 10 micro sock would ease things just frequent sock changes.

The hard part is finding 10 micron sock. Typical aquarium socks are 100-200 micron and the LC will pass right through that even if PO4 is attached to it.

I would not recommend LC if your PO4 is under .10 as it will lower alk.

Thought was Foz Down but appears none in Edm. Guess it's off to the pool places to go bulk. Need socks also as all mine 100's

If you ask your lfs for a 10 micron sock I'm sure they can get them in for you. We can at least here in Vic.
