so im going on vacation in about a month. we go for a week or a little more than a week. anyway i just want to make sure im getting everything right. ill be doing a 50% water change on all tanks the day before i leave. i will swish around my media in old tank water. im adding some filter floss today to give more surface area for bacteria and to remove more particles from the water. i will get my grandpa to feed everyother day. mostly for my juvenile fish and my frogs and crayfish(so he doesnt eat my fish). anything else i should do?
