Lanthanum chloride

are you the curator at Steinhart?

I am a Senior Biologist.

excellent, let me tell you a little story, in part because it's interesting and in part because I'd like to derail the back and forth nonsense that has taken over this thread

I visited Steinhart aquarium many years ago before the expansion. While there viewing the reef exhibit I noticed someone with a bucket and asked if I could have a tour of the back sump/filtration room. Long story short the person I was speaking with was one of the biologist's, I have since forgot his name. He told me they were getting ready to embark on a trip to collect black tip sharks off Christmas island and invited me to come along as the physician for the group. I gladly accepted the invitation however a week before the trip I ruptured my achilles tendon playing racquetball and could not go! :headwally:

Oh boo! When was that?

Oh boo! When was that?

must of been around 1990, give or take a year

I remember the trip was to originate with the group in Hawaii and I believe the black tips were being collected primarily for the aquarium there

:lmao:

I've never been to the Steinhart but I do recall someone there contacting me in regards to obtaining some of my Stichodactyla tapetum

Gents, I have read the first 24 pages and the last 5. Would someone please tell me if something changed or are Garys first page method still the way to dose? Other than the wet skimming. Thanks guys! Please dont make me read the other half.

I still use the original method described in the opening pages of this thread.
My 6 ft long drain lines and 10 micron mechanical filter socks become (in effect) a reaction chamber for the introduction of LaCl3.
I run my skimmer wet during a treatment and replace the wet skimmed water with new artificial saltwater.
As previously mentioned in this thread: go slow and monitor alkalinity and low range PO4.

Thank you Gary

The biggest key to make sure the Lacl3 does not pass through the precipatate filter is slow dosing. There must be sufficent po4 in the water for an "instant" reaction. This is why users employ high flow rates or large volumes of water to ensure that the Lacl3 binds with the po4. To say that it bonds instantly is only true if the concentration of po4 in the surrounding water is high enough for it to do so. Tank clouding generally happens when the rate of Lacl3 is too high for the reaction to take place before the precipatate filter. Protien skimmers are a good place with high flow that can be plumbed to a 5-10 micron sock for occasional po4 removal. Coral magazine archive has a good article, and many public aquariums have used this treatment for years.

Correctamundo.

I agree with most of that;nicely stated.
Do you think more lanthanum binds to carbonate when PO4 levels in the water exposd t o the La are low?
Some folks reported precipitant clogging venturis ,if I recall correctly ,when running it through a skimmer. Have you seen any evidence of that in your application? I never tried it that way ,so any anecdotal information on it would be helpful.

How low can you get the P04 level with that approach?

You just couldn't let it go. Your stupid knit picking ruined what was a stellar thread, congratulations.

I've given this a lot of thought and decided to clean it up and reopen it I removed nearly 100 posts. That's 4 pages of that crap. I can not promise you that taking it back down that road, or the mention of the words "limiting" or "controlling" in regard to algae won't end in a loss of posting privileges here WITHOUT further contact.
You have been warned.

I salute you!!

can i use the Phosphate Remover by kem-tek ?

You'll have to provide some information on the product or any answer is just a guess.

 

[fai4238]

looks they use 7% Lanthanum chloride.

they siad
All of Kem-Tek's products are salt system friendly.

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.

I did this and the 5 micron bags plug up in about one day! (4 x 14). Dosing about 96ml/day on a hourly basis using Bubble Magus doser. Unfortunately the BM failed and now I will go back to my remaining Phosguard.

Great read. Love the chemistry. My PO4 sits at around .14ppm. Might try use the brightwells phosphate E. Will keep everyone posted on how it goes.
