How large are your bass? And for one you should try and stay away from feeders in general. Secondly, if you were to do that they most likely will over eat to death, or just eat all the food on the first day. They probably would not even notice one of those weekend feeder tablets. Your best bet is to find someone you trust and train them on feeeding so they can care for them while your away. Plus that way there is someone to check on your house too!
