i have a AC
70 that i purchased in January for a 29 gallon fresh water setup... the instructions states to change carbon every month, foam every 2 months and bio max every 3 months but to never change all at once... I have a few questions.. if i change the carbon and the foam, every 2 months i would have to change both at the same time, should i wait like a week between changing each one? i dont want to remove the bacteria if i replace both medias at the same time... also, I have heard that i do not need to replace the foam or the bio max, that i just should clean them off.... if i clean the off, how often should i replace with a new one? if i dont go by instructions, then when would i know to replace each one? what is the proper way to clean the foam? i know to put tank water in a bucket, do i just put foam in the bucket and squeeze it out to clean it? this wont remove all the bacteria and now put that bacteria in the dirty bucket water which goes down the drain anyways? i guess im confused..
Last but not least, i also hear that the carbon is a waste, not needed unless im removing medication. is this true? if so, what should i do with the carbon? is there something more benificial to my system that i can put in its place? thank you for the help. .Pete
