My Tank crash - Hopefully you can learn from my experience :(

[hfp75]

My apex would send an email & txt when communication is lost......

Then I have T - however long to get my inverter running....

I had the power go out like 3 years ago for 4 or 5 hours and everything was fine (I was on vacation when it happened and my tank sitter was unaware). I think it depends on a few factors.....

Number and size of fish, volume of water & outside / room temp..... As well have a back flow / check valve so your tank doesn't all run into a sump that can't handle the increased volume.
