Hiya
I really don't get this during regular use at least? One side is clean the other side isn't. If no bugs pass through the medium what is there to grow on the clean side? So why does it need cleaning other than (dirty side only) to maintain through-flow efficiency?
Milton at 1 tablet to 4.5l to sterilise screws up many bottles and tanks if not made of a suitable plastic, maybe metals too. Milton used to maintain water quality at 1 tablet per 100 litres at their recommendation has been fine in our campers plastic tank for long term use. Same I'd imagine just using household bleach, the concentration many organisations quote for adding to maintain drinking water will be a long way from the strength that gets squirted under the loo rim!
