Boomer said:Lanthanum Chloride has been around for years in this hobby. All the liquid PPO4 removers are Lanthanum Chloride. Joe uses it in his system, as many large public aquariums do, as it is much more cost effective for them. For use, we need to stay with GFO which has no negative affect which Lanthanum Chloride can have.
Boomer said:No Bob there is no so called document evidence but one dose not always need that. I will tell you this Randy Homes-Farley and Craig Bingman do not think much of it, especially Craig. I do know that it can at least irritate some animals such as Tridacna. It is also know it is critical to know what you are doing with it and Joe will tell you that himself. It can really haze the water, and coat the glass with carbonate deposits and raise **** with calcifying organisms. When used it is best to use in like in a sump, as a dosage every so often and use a submicron filter to take out the precip particles before they get into the tank. What we need is a means to remove any free La and there is no such means and testing for it will cost an arm and leg. Charles Delbeek has many issues with also at the CAS Stienhart Aquarium, as does Matt Wandell and it all revolves around knowing what you are doing, the dosage and how and where it is applied. Again there is NO reason for its use in a home tank. Public Aquariums are another issue as nothing but GFO is pretty much out of the question for cost. And Daniel Knop from his article is not to big on it either and states so in red type.![]()
