How beneficial/detrimental is it to have activated carbon in your refugium/ canister. I have 1 bag of carbon and 1 bag of chemi pure in my canister and I still see diatoms in my tank. I have a 30 gallon setup with a hob refugium , a protein skimmer and 30lbs of live rock. I use Rodi water as well. My tanks been running for about 3 months now.
