So from my understanding Carbon chips is something good to use for Getting rid or a smell tank or generally clearing up the water if you didnt soak your Drift wood enough. I am moving into a new tank. And i have made my own DIY Canister Filter and i would like to test it. But I was wondering. Carbon Chips are essentially Charcoal, Why not just use Charcoal instead? Is that possible? Because I have BBQs all the time, i was wondering if I could use those charcoals instead of buying expensive carbon chips!
