So i know that dry dosing with ferts is the most inexpensive route and im planning on ordering some ferts from greenleafaquarium.com but what exactly do i need? Do i really need to dose nitrates if have a reasonable amount of fish? From what ive read it seems as if i'd be okay ordering just csm+b, k2so4, and kh2po4. My tank is a 36"-10"-17" 26g, lighting is a 2 bulb 36" HOt5 fixture, CO2 will be coming from one or 2 diy co2 bottles and substrate is eco complete.
