I'd be really thankful if anyone who owns any of the air pumps mentioned in this article https://fishtankclub.com/aquarium-air-pump/ could tell me which one is the best, from either personal experience or an estimation. They all sound promising and I'm clueless and don't know which one to go for. My only requirements are that the air pump has to be on the cheaper side, isn't complicated to install and fairly easy to maintain (although I'm new to the world of aquariums, I don't want to invest in a weak air pump).
Thanks in advance!
