Tchech air filter with air pump-noises,vibrations April 7, 2014 at 6:28 pm #6377 Dorothee Jöllenbeck-PfeffelParticipant Hallo! I’m a bit afraid of old water tanks… Shrimps live in all my tanks, the simonis are a good tip because of the very special water! Are there any further experiences concerning the technic-noises?
