Those moments in reefing when...
 

When you put off that water change for so long, you can't remember if or what you added to the new water.

When that little voice in your head says don't do that, and you did anyway.

When that little voice above laughs at you

When you realize that all those guys that said there's always room for more frags lied...

You lay down towels all around your tank during a water change yet still manage to miss every towel and get the floor wet. Seriously WTF?!

You think back to when someone once told you. 'the hobby is only as expensive as you want it to be'

Thinking, ya one day I will put on a screen top, as you pick up your dried out $130.00 one day in the tank goby..

Buying that fish thinking....surrre they will get along.... **** storm ensues.

When you think "this is the last flood that I will cause".

when you think its a good idea to adjust your skimmer before bed

Oh, ya, that's never a good idea. Never!

when you have back and knee pain cant carry the 5 gallon water beg others to help you

Or when you adjust something in your stand, like add new timers, and knock off the hose from one of your media reactors, shooting water all over the inside of your stand & frying powerheads and equipment JUST BEFORE LEAVING the house ON VACATION. DOH!!!!

For a while I had my equipment trained to breakdown or catch on fire the night before leaving for a vacation. Made the vacation that much more enjoyable. Now you can say I'm an expert on preventative system design. LoL

My system is stable as a rock 51 weeks a year. Leave for vacation, something happens. Evert single time. I can count on it lol
