I've been curious for a long time if there is any concrete data regarding the depletion of alkalinity as a result of the use of lanthanum chloride or GFO. More specifically, do the relative concentrations of phosphate and carbonate play a role in how much the carbonate concentration is affected. If so are there any equations that can be applied to determine the amount of carbonate depletion per unit of phosphate binder added to seawater. I suspect that it's more complex than that, but I can dream.
Would it be fair to say the the propensity of Lanthanum to deplete alkalinity would increase when added to a system with very low phosphate concentrations? And conversely, would one observe a less pronounced effect per unit of lanthanum in a high phosphate scenario.
In any case, I've found both lanthanum and gfo to be excellent methods of phosphate control but prefer to use GFO unless substantial and immediate phosphate reduction is needed. The potency of lanthanum and its potentially unknown side effects deter me from using it on a daily basis. Was hoping some light could be shed on process by which lanthanum chloride and gfo can impact an aquariums alkalinity.
I consider alkalinity as a parameter of pinnacle importance with regard to sps coral health and color so I'd like to minimize any chance of instablility or longterm drift caused by the regular use of phosphate reduction methods. Hoping to gain a better understanding of this phenomenon from the godfather of phosphate management himself. Thanks in advance Randy!
