Thanks Left C So plugging in the following numbers in fertfriend for Kent Pro Plant.

10 US gallons = 37.854118 litres

1/4 tsp = 1.25 ml

We get:

.3302 ppm nitrogen
0 ppm Boron
.0165 ppm magnesium
.0198 ppm sulphur

I guess without knowing the amounts in the tap water being added to the tank and how much exactly the Aquasoil may be leeching into the water column, these numbers don't mean anything, but the point is that he experienced no adverse effects from dosing the phosphate, iron, and Kent Pro Plant trace.
