So I bought the Green Killing Machine and put it in the tank. It is ready to go, right out of the package. Comes with its own pump, attached. You can get a 9 or 24 watt. I got the 24 watt for my 90 gallon tank. It worked wonders in only a few days. I saw dramatic improvement in 24 hours. These pics are after 4 days of it running in the tank.
