I find that carbon n GAC act like mechanical removal filter anyway as water n DOC's pass thru it, hence thats why they have to be clean or removed/replenished. Whats BRS motivation? To sell!
Personally I do no use carbon (unless I feel some sort of chemical contaminate has entered the tank) and I dont use any GAC's as the pellets are doin its job. Just my humble opinion.
Finally I hate cleaning that stuff, bad enough cleaning the skimmer n socks.
Thanks Tom & Harry, I'm planning on removing GAC after it's exhausted end of this week. I'll post up if I notice any differences.
Pssst Doc, isn't carbon and GAC one in the same? :splitspin
Also, I agree with your BRS opinion.
oh btw i clean the glass less often now....once to twice a week vs every to every other day.
Same here! Isn't it crazy? I still find myself cleaning it whenever I look at my tank, which is daily, but it's purely out of habit.
