From www.swimmingpo... this video talks about the root cause for excessive hot tub foam and why commercially available defoamer products are not the right solution to the problem. Defoamer lowers the surface tension on the water and makes bubbles harder to form, but excessive foam in a spa is caused from a deficiency within the system, either the water or the filtration system itself, and this is what enables the foam to happen. Low calcium hardness would make spa water foam a lot because the water is very soft. Too much TDS (total dissolved solids) will also cause foaming and this is an indication that the hot tub water is old and needs to be changed out. Finally, and by far the most common cause for hot tub foam, is failing to degrease your paper filters. If you only rinse your filters and do not use a filter cleaner product then for certain this is enabling your hot tub foam problem.
