Have any of you used bleach to clean filter cartridges, pads, etc.? I just soaked the cartridge for my ocean clear with 2 cups of bleach mixed w/ about 2 gals of water in a bucket for 6-7 hours. I rinsed it out and soaked it again with just water for approx. an hour. After that, I can still smell chlorine from the cartridge and the bucket. I then rinsed it again thoroughly and still smell it, but the scent is weaker. If I constantly rinse it, won't the scent eventually go? Also, would it be safe to use since the chlorine will remove itself?
