Hi guys, I am running a 120 gallon tank via EI method and my tank is 3 months old now and it isnt anything incredible. I am using flourite red for substrate topped with river sand. 312w t5 light 6500k 8 hrs of 156w with 6 hr burst in the middle. 30ppm co2 my co2 starts 3 hrs before the first light comes on and ends 2 hrs before all lights go out. 28 degrees celcius 12x filtration per hour with good surface agitation I have dosing: 1 1/2 tsp KNO3 1/2 tsp KH2PO4 1/2 tsp traces 3x a week. So far I have had average growth. Everything is growing reasonably well except the HC. I intend to increase the dosage slightly as of tomorrow. 2 tsp KNO3 2 tsp KH2po4 3/4 tsp traces I must add that I have very good water circulation around the tank and that the nutrients and co2 are circulation sufficiently. I would like to know if perhaps because my tank is heavily planted, that upping the dosage would be recommended?
