I have a Ultima II that sprung a leak around the O ring area and don't have time to fix it...I think it needs a new O ring...I'm asking 150 since it needs a new part other then that it works fine...I also have a 40 gallon acrylic tank for $30...I will throw in a ac50 with media and light fixture and the tank for 35....Pick up in Rosemead 91770...
