As I occasionally build Zimmerbrunnen itself I was once again on the search for the right silicone for sealing, especially by make are permanently under water. Since it only aquarium silicone suited (normal sanitary silicone begins sometime become moldy), I have long searched for a suitable silicone. Can only recommend the fountain running for over a year and it incurred no mold or other unwanted damages this silicone. The silicone can be processed well, but you should always wear gloves! Strong buy recommendation, although slightly more expensive, it is worth the money!
