Routine maintenance and cleaning
Cleaning an infinity edge and its trough
An infinity edge only looks effortless when it is clean. Scale, algae and debris on the edge show immediately.
An infinity, or vanishing, edge lets water spill over one side of the pool into a catch trough or basin below, from which it is pumped back. The thin sheet of warm water running over the edge evaporates quickly and leaves calcium scale; the trough collects debris and, being shallow and sunlit, grows algae easily.
Routine guides describe one part of regular pool care and how to do it properly.
Regular cleaning keeps the edge clear and the flow even: descaling the weir, brushing the trough and catch basin, removing debris from the trough grilles and drains, and keeping water chemistry balanced to reduce scale. Evaporation from the edge also means more frequent top-ups.
The short version
Scale on the edge
Evaporation from thin water leaves deposits.
Algae in the trough
Shallow, sunlit water encourages growth.
Even flow
Debris and scale disrupt the sheet of water.
Cleaning tasks
Edge descaling
Gentle removal of calcium from the weir.
Trough brushing
Removing algae and debris from the catch area.
Drain and grille clearing
Keeping water returning freely.
Wind and debris
Infinity edges often face open views and wind, so leaves and sand blow into the trough and need clearing between visits.

Common questions
Why does my infinity edge lose so much water?
The edge and trough increase evaporation, especially in heat and wind.
Can scale on the edge be prevented?
Balanced pH and hardness reduce it; regular cleaning keeps it manageable.
Is the trough part of the pool water?
Yes, it circulates with the pool and needs the same chemistry.
Does the trough need its own chemicals?
No separate dosing is usually needed; it shares the pool’s chemistry, but its shallow water shows algae first.
