ok, so I cheat a little and use a small packet of Purigen to my exterior ehiem canister filter. The packet is the color of malted milk balls and needs to be cleaned.
real clear/clean water column
I was told to use a 1:1 water/bleach solution & soak for 5-6 hours or longer
but what is used to neutralize the bleach?
is this safe to do or should I just buy a new packet?
