EI fertilizing for tank volume or water volume?
Because of the 50% water changes, it likely is a moot point. However, I was wondering how you all decide what doses to use in your tanks.
For instance, in my 75g tank. I have 200# of substrate which equates to about 15 gallons of water volume. I will be adding in hardscape (likely some boulders). So in my case it is possible that I may have only 50 gallons of water in my 75 gallon tank.
The dosing amount are quite different for a 50 gallon vs 75 gallon.
Currently I dose for tank size and have no issues with nutrient overload (as far as I can tell).
So, what do you all do?
