We use Oases proficlear systems on our swimponds. This is because they offer a unique way of mechanically filtering the water. They have drums installed inside them that thin the water so its safe to swim in. They also have a biological part which takes care of natural elements found in the pond which can deteriorate the quality of the water. Along with the UV clarifier this creates a safe outdoor swim in the UK.
What’s also great we with these filters is they self clean meaning that maintenance is actually very minimal on these systems.
These can be bottom drained or pump fed installed. If you’d like more information on these filters and why they are the best for swimponds please get in touch.
