i just had to put this on here because i was so excited. i had a 29 gallon tank set up and bought a 75 gallon, using all of the filters and heaters from the 29 on it. so, i had my 75 running and my 29 sat empty for almost 2 months. my girlfriend decided to hook me up and bought me a heater and filter for the 29, so now i have them both running. i have 2 texas cichlids, 2 green severums, 2 firemouths, 2 convicts and 2 plecos in my 75 and 2 kennyi and a yellow labidichromis in the 29. it is awesome!
