Enzymes Make Water Maintenance Easier

By Chris Marcano


Why Use Enzymes?

Enzymes make pool or hot tub maintenance easier. When using them as a part of a routine maintenance program, they work hard so aquatic facility managers do not have to.

Additional benefits include:

Increased filter run cycles

Filters need to be cleaned less and work more efficiently because enzymes are working constantly to break down non-living waste in the water before it has a chance to build up on the filter.

"Those using enzymes on their pools are much less likely to have really bad filter cartridges at the end of the season," Koch said.

In fact, Corney said that using enzymes has reduced the number of filter backwashes by 50 percent. "Customers really like the idea of backwashing less, because they realize they are saving water."

Further, Corney said his service team has to work less at keeping the pool and water clear since they started using enzymes. "We are even using an enzyme that is formulated for cold water so we can use it for winterizing," he said.

Enzyme products make pool or spa systems much more efficient, Rullo added. "By breaking down non-living organics before they get into the pipes, the filters do not have to work as hard to keep the water clear, thus the filter media stays cleaner longer."

Reduction of scum lines

Reducing scum lines means less scrubbing for pool professionals. When non-living organics partially break down, one of the places their remains like to stick is at the tile line. All maintenance professionals have seen this unsightly buildup at times, and enzymes will work to prevent it from coming back.

"We never have the issue of 'ring around the pool' with enzyme use," Koch said.

Before using enzymes, it was a given when opening pools in the spring, there would be a ring around the perimeter of the pool at the waterline. Because the water level is dropped for winterizing, the ring would be even more pronounced and visible than during the season—more at the mid-point of the tile line.

"It's natural to get a ring with the organics accumulating at the water surface, however, by using enzymes, my service crews are more efficient because they don't have to work as hard and spend time removing the ring manually," said Koch. "Sometimes scum lines can be really tough to remove because organics can actually edge themselves into porous surfaces."

Superior water clarity

When there is less "stuff" (non-living gunk and grime) in the water, it will show in its appearance.

"We recently dealt with an aquatic facility for seniors that had problematic water—it was also cloudy and wouldn't hold the required chlorine readings; we couldn't figure out what to do," Rullo said. "As a result, the pool was put on an enzyme-based water treatment program. It took approximately two weeks to resolve the problem, but eventually the enzymes removed the byproducts in the pool water and pipes."

Much like the rest of the world, the pool and hot tub industry—in this case water treatment—has evolved significantly. That said, considering a proactive pool and hot tub maintenance program as an alternative to the traditional "put out the fire" approach, service professionals can be much more productive.
