HELP! DESPERATE! This is GSPO. The only cacti to survive me for multiple years (going on 6 or 7?). He's lived in this fish tank forever without any problems but one of my last waterings did too much and I think there is mold. (Amazoned a real container to be here tomorrow) QUESTION: what special things do I need to do before the repot? Alcohol or anything? This cactus is my life.
