UPDATE:
I have not been dosing since I'm using both Powersand Special and Aquasoil and have been told that will provide all necessary nutrients. I was worried so I tested the water this morning with my LaMotte kits. Holy lords of perfection!!! NO3=10 ppm and PO4=.2 ppm. Without dosing! This stuff is not only the nicest substrate I have ever played with but it maintains nearly perfect nutrient balance in the tank without dosing. What could be easier. I am dumbfounded . . .
You can use EI dosing with Ps and AS, or with AS alone also.
Plants will do better than without any dosing/trace dosing.
Some folks have supported the myth that adding ferts will some how hurt or otherwise harm the tanks with ADa substrates and that is plain rubbish.
This is simply not true.
There is no reason why that would occur.
The NH4 is removed if you plant heavy right away from day one and add enough CO2.
Both AS and Ps have the same relative amount of the NH4.
If you use water column fwerts, this will, extend the life of the ADA AS and PS also, since the plants will not draw from that, this also affords a backup in case you forget to dose the water column etc as well.
So you get the nutrients in the root zone and on the leaves, the best of both worlds.
Don't be fooled by the notion that excess water column ferts will lead to algae, that's not true and never was.
You do not have to use all things ADA and follow the precise method (Ahem, marketing) they suggest.
Just like 20 years prior you did not have to use all things Dupla when they came out with all sorts of things, some did work well, most really did not matter.
But few of you here today recall those discussions of days past
Same old thing all over again.
