Zodiac Clearwater C200 / QC270 cell. Electrodes are approx 150mm long. Model numbers are different in Queensland. The QC270 is the model number for Qld. It is the same cell.
Earlier Clearwater cells had a clear bayonet cap, where the later models have a white screw type cap. Screw on cap only available now in the genuine cell. Our non-genuine cell has a bayonet cap available.
