Common Questions & Instructions
How much surface area does one 1 QT. bottle cover?
Coverage varies based on the severity of the scale, but one bottle typically handles the waterline of a standard 15,000-gallon pool for a deep cleaning session.
Is Bio-Dex 300 safe for use on fiberglass pool shells?
Yes, this formula is safe for fiberglass and is often used to remove the 'bathtub ring' of oils and minerals that accumulate at the water level.
Does this cleaner affect the pool's water chemistry?
When used as directed and rinsed properly, it has a negligible effect on pH and alkalinity, though it is always best to test water after a major cleaning.
