Excellent for carpet growth

I’ve had excellent luck growing my mini hair grass carpet with this fertilizer. I have a high energy system (60 PAR, 30 ppm CO2, 7.5 ppm O2) so I have been dosing 5x the recommended amount of fertilizer daily to ensure there are no nutrient deficiencies in the tank (and to stop any feast/famine cycle). I combine this with a 50% weekly water change. All of these steps follow George Farmer’s recommendations for a high plant growth with the EI method.
