Of the air pumps on the market today what do you consider to be the top brand and best operating unit? I can not remember which brand I have had over the years. I have been out of the tropical fish (fresh) for about 4 years. I am in the process of getting another 75 to 125 gallon tank. I prefer the larger tanks to me much easier to maintain. With a good canister filter and accessories its a fun hobby to have. I was in it for about 30 years and miss it. a lot has changed almost everyday and that includes air pumps. I usually run 2 bubblers so need a pump maybe handle a third. All feedback greatly appreciated.
