Just a quick FYI: My husband (who usually leaves the pool stuff to me) has discovered that using an old (or new, depending) outdoor cooler is just the right size for our cartridge filter. It submerges completely (on its side) and the cover can be shut if need be to protect dogs and small kids from messing around with the water and cleaner. The strongest we have used for cleaning is dishwasher detergent and it has worked well.
Hope this little tip can help someone else.
