It just comes down to dosing correctly. I use dry fertilizers and I know exactly how much NPK and Micros I'm dosing. It's a leaner Estimative Index regiment, but the same principles apply to non CO2 tanks too. Just have enough nutrients in the water, proper light and CO² and the plants will thrive. If you don't use CO2, then bring the light intensity down and the fertilizers too.
If you're interested, just Google Estimative Index dosing.
