My tank has been cycled for around 2 months now. I decided I want a newbie friendly planted tank. Last week I switched the substrate to sea-chem fluorite. I have just ordered 2 Dwarf Subulata and 2 Green Myrio plants. I have on hand already Flourish Excel. Is there anything else I might need before the plants arrive in a couple of days ? Im running a 32 watt aggrosun 6400k light.
