I agree Cerreta, larger costs, larger water changes, larger pumps etc but........LARGER REWARDS!!
You can always find reasons not to do something, but this is a hobby and I think you have to keep striving further in the hobby or else it will become mundane. If people didnt strive and challenge themselves in this hobby we wouldn't have alot of the technology and education we have now.
People who like cars for a hobby don't go to pick one out at the junk yard because its cheap. They go for the their favorite car and the best one for their money. They wouldn't say, "Hey I will take that Dodge Neon instead of that Dodge Viper because the neon is better on gas mileage, and it has a small gas tank, and maintenance is cheaper." No way, if that is your hobby, you take the Viper!
