I added some several weeks ago and am curious if i need to add more because of water changes and it losing its effectiveness. thanks

i already have it as substrate

i was just curious with cleaning and it being sucked out while cleaning the sand and it comes out while doing water changes if i can add more back . sorry if confusing.
