I bought my 10 micron bags from zoro tools

I've been using the steel rings for years.
It's okay.

No rust issues? How about the material the bag is made of. Seems like polyester felt or polypropylene felt are the two most common. Is one better than the other for this use? I also wonder if the welded seams would be less likely to allow the LaCl3 to pass through the filter bag.
Stainless steel rings are doing me fine. They take a beating in the washing machine, but they easily bend back into a round shape.

Just got off the phone with Utah biodiesel and they don't carry the socks with a SS ring. They are carbon steel.
I suppose I could have misunderstood, but I bought mine believing that they had stainless rings. I know that good stainless will not rust. I'm pretty sure Carbon Steel is non ferric, and also will not rust. I wouldn't bet my house on it, though.

carbon steel will definitely rust.

Haven't read the entire thread, but based upon the above:
1. Use SeaKlear and dilute 5:1000 w/RODI water;
2. Dose this mix at 1.1ml/min = 66ml/hr = 1584 ml/day;
If I do this instead to reduce dosing amount:
50 ml LC : 1000 ml RODI , ie x10 above
Dose at 7ml/hr = 168ml/day via Dosing unit (Bubble Magnus)
Therefore, dosing liquid will last longer.
Dose into inlet of pump on a reactor filled with filter floss to remove precipitate.
For a 300g FO system.........
Current PO4 - 0.10ppm
LC dosing experts....is this ok?
OR I can just drip into a 5 micron bag in sump....

I think I will just use the reactor (1 liter TLF) as a mixing chamber and the outlet will dump to one of the 5 micron filters.
Just need to figure out which place to get the filters.
I will just dose the LC at the inlet to the pump on the reactor.
Look like poly flange, so no metal exposure, but very large!

5 microns 4" dia x 14"...smaller...poly ring!

I will go with 150ml LC: 1000ml RODI and then just does once per hour at a rate of INITIAL - 2ml/hr x 24 = 48ml/day
Bottle of 2 liter solution should last one month. One quart LC should be good for 6 months.

Some smaller sizes here at Filterbag. (min. 25 bags!)

My concern ,if using a reactor without a brisk flow through it is that there might not be enough water volume and PO4 exposure to precipitate all the lanthanum that goes into the reactor letting it flow through the filter into the tank. Slow dosing and healthy flow through the reactor can help that.

I haven't really heard any benefits to using the confined space and relatively limited water volume of a reactor. I don't understand why some folks seem to prefer that method; if there are benefits I've oerlooked I'd sincerely like to hear them.
When I dosed LaCl to my system I dosed it with exposure to a lot of circulating tank water pre filter: into a drain; through a bottom up flow 32 gallon brute cryptic refugium; out over a sand bed; then through a well packed floss filter ;then into the sump ahead of the skimmer and return pump.
Even with all of that water exposure slow dosing was required to prevent post filter clouding.
I never cared much about any precipitant left behind but focused on keeping it out of the tanks and ensuring free lanthanum had a chance to precipitate before getting to the tank.

You are correct, Tom
You are correct, Tom
LaCl3 bonds instantaneously.
A reactor is definitely not a necessity and might actually reduce the effectiveness of this method.
Mechanical filtration IS a necessity.
IME good skimming helps, too.

One could certainly place filter floss in the reactor prior to the water discharge to the 5 micron filter. That would be increase the life of the post 5 micron filter. Definite benefit.
The reactor allows the water/LC input mixture, in my case 1 liter of volume, to be the filtered source compared to the limited amount of water in the 5 micron filter that would occur if one were to dump LC into a filter.
