going on 5 day vacation, any tips on preserving tank?
I have a high tech 21g tank and am leaving next week for a 5 day trip. I have no one that can come by to check on it, everyone i know is leaving then too.
Any advice on what I can do to keep the tank from blowing up while I'm gone? Lighting and CO2 are on timers already. I have about 20 cardinal tetras and harlequin rasboras.
Should I turn down the lights and Co2 a bit maybe? let things slow down a bit
What works for feeding fish? I'm debating an automatic feeding thing, but they're a bit pricey for something I'm going to use once. Do those feeding blocks that supposedly last several days work?
Any other tips?
