Wondering how much longer media is lasting for people who use recirculating scrubbers ? I used to get anywhere from 4-10 days, with the media beginning to change pink hours after replaced. Recently hooked it up as recirculating and it hasn’t even begun to change after 3 days. Does this seem right, or could it be too humid for it to work properly? My PH has remained where needed so I’m just assuming it is lasting much longer but wanted to consult the masses here…
