I'm totally clueless on how to go about picking the right air pump and stone/diffuser (I actually heard that micropore diffusers are better?) to help bubble my nute solutions. I just need to be pointed in the right direction on which type of pump to get and a quality air stone or diffuser needed to bubble only 1 gallon of nute solution 24 hrs prior to feeding. Any cheap, reliable and quiet ones I should look out for? Would it just be better to go get one from say a pet store? help is appreciated.
