@CometKeith Is the Laguna Pressure filter you bought running on it's own or did you connect it to another pump as they suggested at azponds? I do have the Laguna Max Flo waterfall and filter pump already.
They suggested:
The Pressure-Flo filters are designed to work in tandem with a solids handling pump, such as the Laguna Max-Flo Waterfall and filter pump. With the filter connected to the pump, water enters the unit through a water inlet. It then passes through the mechanical filtration stage, consisting of highly durable foam filters that intercept and trap dirt and debris.
Dirt-free water then passes along an integrated UV-C lamp, where it is exposed to ultraviolet rays that inhibit the growth of algae. Finally, water returns to the pond thoroughly cleansed. This patented system is the only one of its kind. Backwash cleaning can easily and comfortably be completed in a few minutes without opening the lid. This feature ensures that the filter performs at optimal levels for many days and prolongs the time between full maintenance sessions. An easy-to-view cleaning indicator signals when it’s time to perform backwash cleaning.
