I bought some Tonina sp. belem last week and it seems to be settling in okay but I'm just wondering from those who grow it what basic things you provide. I have it in a 90 gallon with flourite/eco-complete mix, 220 watts cf lighting, and pressurized co2. Kh is 4, gH is 8, temperature is 80-82 F, and I put a small bag of peat pellets in the substrate around the stems. What should I be targeting for nitrates? Any other tips?
