Aquarium Paranoia

Considering disasterous eqipment failure likely leads to some of the other problems listed, I have to vote for that one.

Depends what disastrous means, eh?

Yeah I thought equipment failure would trump everything else. Maybe I should've asked which is a prevailing concern. I'm sure equipment failure is at the back of everyone's mind, but we learn to trust them and so our immediate concerns focus in on some other problem.

My vote was for cost. I have an empty 55 gallon that I've been wanting to start up so badly. But I keep thinking of better ways I could spend the money.

Ahh! I should have added "time investment". That's another concern I have.

I was just sitting here when the air tube fell off the CO2 solenoid, due to heat or something, leaking CO2, -the solenoid gets pretty hot so had to figure a fix for that. A few weeks ago another CO2 tank all leaked out just after being re-filled, so trying non-CO2 on that tank. Also water leaks. : (
