Hello everyone, Today we had a power outage for 2 hours. The two tanks I have were quiet. No filteration, no aeration, nothing. to top it all the temp started rising and I panicked. I did a 20% water change in both tanks to help cool and aerate the water. Luckily the power came back in 2 hrs. How long can GF stay without filteration and aeration? Does anyone know what else can be done in an emergency or if the power goes out for longer periods. I wish we could have an emergency plan for our fish tanks. Can people help me make one that will be useful for all? Its better to be prepared than land up with sick fish.
