The Tidal™ Pump is self-priming which means there is no need to fill the filter basket with water, start a siphon, monitor the filter, or any of the other headaches of starting a new filter. This also means that filter will restart itself with no trouble after a power outage or after maintenance. Replacement Pump for your Tidal Filter 35 Easily clips onto your Tidal Filter 35.
