Amazonia II cycle subtrate questions
so my tank has been set up with regular sand for 2 weeks now , with java fern , driftwoood , anubias , amazonian sword
its a 7.5g
and i recently bought a pack of amazonia II subtrate
if im going to replace the sand with the subtrate and start cycling , will i need co2 to cycle the subtrate? and will my plants die without the paintball co2?
so far its just a heater,filter,light my diy set up parts havent all come in yet
