Clearing up stuff from my old tank that was decommissioned earlier this year. I have 02 x Hydor Koralia Nano Wavemakers for sale @ $20 each. Flow rate is 900l/hr. Ideal for nano 2ft tanks and smaller. Both cleaned up and in good working condition. They are about 1.5 years old. Comes complete in their respective boxes. Please contact me at 9769644five if you are keen. Thanks.
