Lanthanum reactor

nanomania · Apr 18, 2016

Hey guys, i know about lanthanum chloride, though never used it, but would like to know if some one has tried this method with a reactor. I know it depletes alk, but im sure it can be added. I would like to know the dosage of it per gallon. Iv read that u need to dissolve 6ml in 1liter ro water (is tht correct?) and then drip it slowly but how to inject into this system or can we jus drop in near the pump intake of the filter? Also i dont want to add too fast, i would like to add very little everyday and bring levels down in a week to a months time then continue with the drips for maintaining the level. I dont have high po4 as of now though, but planning to experiment for my future build. As im into chemical business from india, we get 99% pure lanthanum chloride powder (i guess, will still find out n update)

Here is a commercial reactor for lanthanum but its way too over priced...

I use it off and on and would probably just get another drew's doser to dose a drop here and there. No need to dilute it. (using liquid not powder; maybe just mix it to saturation and use the liquid?)

Well but its 99.99% so how to dilute? What % of LC in water?

Well if it were me, I might get an aquarium product, then several cups with saltwater. Introduce some phosphate and compare a drop, test, drop, test, average things out, then work to replicate that. Though I would imagine it's probably up to you. The more concentrated the harder it will be to avoid shocking the tank with 1 drop vs 10-20 drops. I want to say from the one I use, 1 drop in 30ish gallons takes phosphate down by .05 each drop.

Make sure to drip it slowly and try and drip it into a filter sock (be careful though, it clogs the sock pretty quickly).

This is
PHOSfree by natural chemistry. It cost me 25 bucks CDN with tax and is 2 liters. Was bought at a pool store.Compared to Phosbuster at 33 bucks CDN with tax, your getting 20x more product at a fraction of the cost. Now I know some might be thinking well is it safe? Says product will treat 10,000 gallons with a total phosphate concentration of 1000ppb, converted to ppm is 1ppm phos. 
 
Here is the composition of it: 
Composition and Information on Ingredients 
 
Lanthanum Sulfate 3-10 %
Lanthanum Chloride 5-12 %
Sodium chloride 2-5 %
Water 75-88 %

Good point about the sock, though not entirely necessary it does cause irritation if it lands on critters..
Iirc the mean particulate size created is 15-60 microns..

Yup, but howmuch powder to dilute in water to make it easy and safe to use for aquariums?

This might help... Though I would probably test like I wrote above just to be sure it won't be too much..

The convenience does come at a price since 500 ml of derKroon Mechanics Lanthanum Chloride solution, which contains 800 mg per bottle, retails around $24 USD. As an alternative, it is easy to fin 50 grams of reagent grade lanthanum chloride online for $92 online (feel free to do the math). You can also get a smaller 250 ml bottle for around $13.

Each 250 ml of derKroon LaCl3 solution will remove 0.8 ppm phosphate in 1,250 liters of water you’ll still be saving a little over GFO.
