I recently bought a Poseidon Reef phyto and pod culture kit. Just did my 1st weeks harvest. Everything went pretty well aside from some procedural stuff (need to buy specific bowls for this). Had a quick question. I put the phyto that I'm keeping for the tank in a large Mason jar. I sterilized it with alcohol before filling it. My question is: Is sterilizing this container necessary if it's being stored in the fridge anyways? Second question: do I need to sterilize the measuring cup that I'm using to measure out the daily dose before I pour it into the tank?
