I'm gonna be doing some shopping so I can get everything necessary to set up my tank and start cycling. I have tank,hood,stand,filter and heater. I'm going to get substrate (not sure what yet), API freshwater master test kit, pure ammonia, thermometer and seachem prime. Is there anything I'm forgetting? I'm not gonna need a gravel vac yet....right? Getting nervous about cycling so I feel like I'm forgetting. Thanks for the help
