Charcoal and Additives

[aquafreak]

I've recently added charcoal (in nylons) to my sump for extra water quality. I would like to know whether or not this would neutralize any reef additives. I would like to add Seachem vitamins for the aquarium.

Yes it can pull out your chems such as elements and vitamins. I don't think it strips it completely. I use it and just add the trace and iodine weekly to replace what's lost. Some people only use charcoal occasionally to clear the water. Regular water changes and element replacement should fix what the coal does.

Thanks very kindly. I was wondering about that.

Kat is right. Hoever, skimmers can also remove some trace elements and many of us use them. that is were regular maintanance comes in. If you are worried, just run carbon for one week a month. That is what I do and my water remains crystal clear. It should really be changed out after one week anyway.
