Very true. Most of them are fairly new at the hobby and want it all right away. They don't usually last anyways but the time in sure kills a lot of livestock.

It is stressful though when your working out of town and your wife is calling you pi$$ed off and in a panic cause your herby had screwed up and your tanks overflowing. Teach your significant others what to do in emergencies.
