Not if we want to eat or pay the mortgage. When we do use it, the lowest we'll set at it is 75, takes the edge off the heat for us and the fish do just fine in it.
This picture shows exactly why people shouldn't get into the hobby on that scale if they can't afford to do it right or refuse to spend the money to. I didn't have all the cash to set up my 210 when I got it. I spent 3 months slowly getting it up and running. I feel good knowing people can get close to my tank with fear for their life. That's unless they think one of the fish is going to get them. lol
