| | Re: Ferts for fishless tank?
The amount of ferts you will need will depend on how you're planning to set up the tank. How much lighting, and what type of plants you're going to grow, etc. Since fish concerns won't be an issue, you can crank up CO2 here without any worries, and just add dry ferts as you would otherwise in any other tank. In any case, start slowly to achieve better stability over time.
