For me, the appeal of this method is avoiding GFO and only introducing aragonite sand which is already common to a tank.Imagine using the regeneration method with GFO instead of sand. Would the GFO have more surface area than sand to adsorb more PO4?
For me, it’s to save money instead of repeating buying GFO, but to have a similar efficacy as GFO. I use high capacity GFO, and it works like a beast. I can’t imagine coarse sand outcompeting it when comparing the same volume.For me, the appeal of this method is avoiding GFO and only introducing aragonite sand which is already common to a tank.
(And small amounts of Lanthanum, but already attached to solids)
Randy answered this question already here: https://www.reef2reef.com/threads/does-silicate-bind-to-rocks.1030048/Oh, while we're on the topic, what do we predict would happen to Silicate from the tank water in this process?
(Does it attract to aragonite like PO4 by similar mechanism?)

I think the aragonite sand is the attractive part, using that to lower PO4 has been an appealing idea to many. But Garf's lanthanum regeneration cycle (to quickly pull PO4 back off the sand) seems to be what actually allows the GCCM to work to remove practical amounts.LC use or the sand?
Eh, maybe not ideal. If the co2 goes into the system right at the aragonite bag then some of the CO2 may not be bringing down the water pH, but instead dissolving the aragonite.the addition of CO2 immediately before the bag could have implications (yes, I could change this, but don't want to, yet).
Yeah, I'm hoping I've learned a lesson or 2 from my algae scrubber CO2 experiment 11 or 12 years ago. Grew algae like stink, and dissolved everything made of calcium carbonate down the one end of the sump, lol.Eh, maybe not ideal. If the co2 goes into the system right at the aragonite bag then some of the CO2 may not be bringing down the water pH, but instead dissolving the aragonite.
(If the co2 is well mixed with the water first, and the water pH isn't in the 7's then aragonite dissolution is not a concern. )
