Improving CEC with Aquasoil

[Infulgeo]

hi I'm wondering if ADA Aqua Soil will continue to last in a NO CO2 setup with water column dosing. If this is an unlikely event would it be prudent to increase the CEC with say a topping agent like black Flourite sand or the like? If ADA has a high CEC contrary to what i've read then please correct me
Thanks again for all your replies this forum has brought me a long way in such a short amount of time.

Hi, Tom's report reported ADA's CEC was the best among all tested soil/clay (delta clay, pond clay).
Actually old AS had better CEC than new.

Thanks alot for the info, i had heard that overall AS I is better than AS II. Would you say that AS I has a decent CEC Overall or just in comparison to AS II?

The report used Amazonia I

Anyway, since clay has high CEC.
So I wouldn't worry about CEC in any clay based substrate.

quite the logical deduction
