Update on use of Lanthanum chloride

I have been able to increase the effective life of my GFO media (in reactor) by 1x weekly dosing of 5ml LC diluted with 1 liter of water into a 10micron filter bag for 65g total water volume, and maintain the phosphate in the .04-.08 range. I'm using the Phosfree product. Like someone posted here, it seems a 1 liter container of Phosfree will last a lifetime. I think I paid $29. I have noticed that my sailfin tang/s breathing does seem a bit labored during the treatment, but because I dose over a 3-4 hour period (slow drip), the water stays fairly clear, and the effect on the skimmer, while noticeable (finer bubbles), doesn't overflow the skimmate into the collection cup. I have not noticed anything but positive results from the dosing of LC. When combined with occasional regeneration of the GFO, its a very cost effective way to manage phosphate levels.

Happy holidays and reefing!

This sounds like a solid plan. Wondering how much LC do you add. I have my live rock in a 32 brute.

The dilution level ,ie % of lanthanum chloride to water varies from product to product and is not clearly stated on any of them. It used to be available on mds sheets but is no longer ; I guess lanthaum chloride doesn't require listing.So, the amount you need to dose varies depending on the product and the amount of PO4 lyou need to remove. A little extra shouldn't hurt anything in a curing bin set up. FWIW, I use Sealkear ,starting with one capfull per day to the 32 gallon bin and adjust it up or down based on remaining PO4 levels.
 
You are welcome.
Even the Seaklear no longer lists the LaCl content and offer a line of products which vary in strength. I'd start with one capful per day . Test PO4 after a few days ;up it to 2 capfuls if needed.
 
What about reagent or lab grade stuff? You guys have any success with it? Just asking cause that's what came with the DK reactor.
 
@ Bling_bling466 , @ Tracey2 , Seaklear is not available up here from what I could see. I purchased a product called PhosZero by RBF international (Pool Supplies distributor) - their MSDS states 10-30% Lanthanum Chloride diluted in water. No other ingredients. The pdf is to large to post here, but I can email it if anyone wants it. I purchased a 1L bottle for 15$ (From Trevi - pool store in Montreal). It's gonna last a lifetime.
I just decided to use LaCL and Carbon dosing to get my tank back in check. After 10 years of neglecting a FOWLR and converting it to a reef, I'm paying the price for not being more on top of it. From what I've been reading for what seems the last 6 months, the key determinant to success is to start slow and adjust up in dose, be sure to have a very good skimmer and have extra methods to keep your phosphates low so you don't have to dose too frequently. Testing is also key when using, be sure to test your phosphates and nitrates and alkalinity before starting. Be sure to test you water again the next day, 24hrs later. I wouldn't wait a couple of days, this stuff is potent enough to drop your PO4 quickly and you want to drop it by 0.5ppm per day. Watching your alkalinity is important as LaCL can drop it suddenly.

Just adding my 2 cents and probably repeating what others have said in here, but reading 50pgs was too much. :-) I'll try to have some before and after photos.
 
I actually picked up a HOT Magnum today just because it had the 1 micron cartridge in it. I've had it on my system for maybe half a hour and it's clearing the precip up very good. I am gonna try to leave it on for maybe a hour or so and then take it off. But it's doing an excellent job of pulling. I wonder if next time i should just drop drops in front of the intake...???
 
Looking for 10 Micron or 5 Micron Socks

Looking for 10 Micron or 5 Micron Socks

Hi, if someone purchased 5 micron or 10 micron socks in bulk and would like to sell some of them to me please let me know.

I would like to try my hand at dosing this stuff but dont want to have to buy 25 socks not knowing if I am going to like dosing this stuff. With shipping 25 socks would cost me about $75.

I just need a few socks for a test run.

If you have some for sale please let me know.

I've been buying 10 and 25 micron filter socks from this site (hope link works), if link doesn't work just go to ebay and do a search for 10 micron filter socks or dudadiesel (store). I usually buy in lots of 5 but you can only get 1 if you want to. Im using lanthanum chloride I also got from ebay. Got a quart for 43.00, socks are about 6.00 each. Shipping included. I use the large 7x16 inch socks 10 micron in a 5 gallon bucket.

Its been working quite well. But I use 4 socks per day on if phosphate is high (1.2 on my 300gal tank) I have a very simple set up. two 5 gallon buckets. I mix 15ml chloride to 1 gal or RO water and drip it 1 drop every two seconds into bucket one (about 26 hours). I am using a siphon from my higher (refugium on floor 12inches of water) level sump at about a gallon per hour to bucket one. I have a small 7watt mix pump that keeps water stirred up in the bucket, a lot of the phosphate will precipitate in this bucket (buckets are easy to clean) I siphon from bucket one to bucket two that has the sock in it. I keep a small mix pump inside the sock to help keep the precipitate from settling in one spot and having to change quite so often.The water outside the sock is then siphoned back into my main sump (6 inches of water) with the line placed in front of the pump to the skimmer in my high level sump. Both buckets are a little taller than my high level sump so there is no chance of any spill if sock clogs up, the siphon just quits is all. The phosphate plugs the sock pretty quick depending on phosphate levels, but the slow siphon allows it to work longer, as long as the sock stays wet, its pretty easy to wash out with a water hose and reuse.
 
Hey guys! I just wanted to thank all of you and share my LC experiences.
A little over a month ago I went into the LFS for a giant bucket of GFO and was sent home with a little bottle of thrive phosphate remover and 100 micron filter sock. Thankfully I did a bit of research before dumping the bottle into my tank and waiting for my PO4 to disappear. After getting some 10 micron socks I dosed that whole bottle of thrive over a week and still had a reading of 2.50 PPM on my hanna, so I picked up a bottle of Phosfree(super diluted 11%LC but better than thrive). I started with 4 oz to 1 gallon of RO dripped over 24 hours into a 30 gallon tank that overflowed into a sock. That rate is high but due to my very high PO4 level I did not have to worry about any LC making it to the DT. I finally got down to .3 ppm and lowered my mix down to 1 ounce per gallon per day and plan on keeping that up for a few days. I am guessing I will have quite a bit of bounce from the several thousand pounds of rock.
 
I also want to note that total system volume is 2500 gallons. Also I saw no ill effects on 3 yellow, purple, sailfin, scopas, and all other non zebramosa tangs, or clams. This was just my experience from properly administering LC.
 
Just as a follow up, my water is moving at 10-20 gal per hour, not 1 gallon. I started out with a po4 of 1.2 according to my hanna, The system was neglected for about two years after a fire and lost all my livestock, but kept water pumping to keep smell down. Started it back up a few months ago and started restocking. Aipstasia have almost taken completely over. Added about 30 berghia and they are doing a good job on that. My biggest problem is there are 0 nitrates but the po4 is high, didn't seem like water changes and macro algae were helping much. The lanthanum at 15 ml mixed with gal water per day has now lowered it to .18 over last 3 weeks, still has a little ways to go, think a lot of phosphate got locked up in the rock and will take awhile. But the lanthanum definitely works, also have gfo running, but does get expensive.
 
wow, 2500 gallons. Is all of that in one DT or several incorporated tanks. Ought to be one nice display. You buy your salt by the pallet or fortunate to have a tanker or direct line to the ocean.
 
I thought 1 gph seemed a little slow....That would take almost 2 weeks to cycle all of your tank water 1 time!
My main tank is only 1500 gallons, about 700 gallons of fuge, the rest misc. frag tanks and filtration.
I had a fire in my house about 5 years ago too. Not caused by my tank though. Thankfully I was just restarting my 150 at the time and did not have any livestock.
 
I just tried lanthanum chloride for the first time the other day. I used 3ml of seaklear phosphate remover(not the cr). I mixed it with a liter of rodi and dripped it over a few days. Could this cause stn in sps? I have a few corals going through stn now.

Tank is 180g w/ aqaumaxx cones co3 skimmer. I used a 10micron sock and dripped through the tank drains. nems, clam, and lps seem fine. I tried this due to diatoms, cyano, and a little ha.
 
It can use alkalinity and or create a rapid drop in PO4 ;either of which can contribute to stn.Wha t is your alk level? What is the PO4?
 
Some types of algae can do fine in very low PO4 water.,bryopsis and rhodophyta for example. It's also possible the algae you have is better at grabbing some organic phosphate than some of the coral or may be picking it up from the rock or some localized detritus accumualtions. For me sps do very well with PO4 in the 0.02 to 0.04 ppm area per the hanah colorimeter.Some folks go higher. SPS and other corals and animals need some phosphate for life , ATP, phospholipids, protein phosphorylatation ,DNA, RNA for example.
