Hello! New to the forum and wanted to ask a question. I recently set up a tank for my elderly mother. The tank was a gift. Its a 75 gallon tank with a BioFilter system. I believe that is what it is called. I set it all up and have it running very nicely. My mother loves fancy goldfish so I have some of them in the tank. Unfortunately, my mother is disabled and is not able to physically feed the fish. I do this for her, but sometimes work takes me out of town. I was wondering if the automatic feeders I see on the market are any good? Do you guys have any suggestions or comments about these? Thanks and have a good one!
