Hey Hoppy, thanks for your reply. The confusion for me though is how to define heavy dose. For example, the mixture I put in to saturate the substrate was a mixture such that for 1 gallon of water (roughly what I used to saturate the substrate) it had 90ppm of Nitrates. However this same solution dosed for a 10 gallon (filled) tank would be 9ppm which is much more reasonable.

So when you used your premixed doses for your emersed glosso tank, I'd imagine that the ppm with respect to the much lower amount of water in the tank(substrate) would still be relatively pretty high? So I guess what I'm asking is that should I be aiming for dosing the normal ppms, relative to the amount of water in the substrate, or relative to the tank capacity once it is filled?
