vear Posted June 15, 2017 The day before my water change I take the filter off (HOB) and clean out the filter floss and dump the water out of the filter. Give it a good scrubbing. Then I will change the water the next day. Do only one filter at a time, never both filters at the same time I only use one canister filter. I wash all of it and don't really worry because there's no chlorine in the water. I definitely do not clean it once a week though. Should i be cleaning it once a week? Also should i worry about cleaning the entire filter all at once if I use well water?Sent from my SM-G930P using Tapatalk Quote Share this post Link to post Share on other sites
