Then how much of a water change do you do to feel like you're effectively replacing trace?
Along the lines of filter socks..... I stumbled to the rotter guy on a youtube. I can't say I'm a fan of any of his videos.... but that rotter tube... I can see it does something... but it baffles me how he tries to "sell" it.
I do 5 gallon water changes probably once every 1.5 months
