If you're planning to get some laps in at the new Kiwanis Aquatics Centre, think again.

For the second time in recent months the main pool is closed - this time due to filtration problems.

The theraputic pool is still open and scheduled lessons are going ahead as planned.

Rick Lane, Director of Recreation and Community Services for the city of St. Catharines, tells 610 CKTB News that the main (lane) pool could re-open by as early as tonight.
