This would make a great addition to your fish tank, and it’s a good starting point for a complete automation system. Alan admits a simple stick-on thermometer would have worked, “but what is the fun in that?”

When the tank is cleaned the fish are removed and placed in a small amount of the tank water. The problem is that fish don’t like rapid temperature fluctuations. I guess a simple in tank or stick on thermometer would have done the trick but what is the fun in that? If the unit just did temperature monitoring it would have been such a waste of processor capability, so I thought adding colored lighting would be a great addition.
