Subject: How much carbon?

The recent discussion about carbon lead me to wonder how much carbon to actually use. My carbon is from a bulk buy and is just in a bucket w/o directions for usage...   I've read that it is best to use as little as you can with the general guidelines being 3 level tablespoons of carbon per 50 gallons of actual tank water.   

So how much do you use in what size tank and how and where do you "add it"?  (reactor, filter sock, mesh bag, etc... first chamber, last chamber...)  Does anyone have a preference in brand?

Here's a link for you man. Use your estimated actual water volume and pick your type of carbon.

I previously had been using at least 1 pound of carbon in my 150. I was just putting it in my filter sock.
In the last two months i have changed over to Clear FX Pro and love it. I run it in all my tanks. It is especially nice in my cube with only a HOB filter.No need to run multiple products. Carbon GFO ect.
Personally i  think it really depends on your Bio Load. IMO more the Merrier except on your pocket book that is.LOL

Hmmm, i put like 1/2 a cup in a mesh bag, in my filter sock... I wonder if that is too much for my 75

Placing the AC in the filter sock is not so good because the churning water may pulverize it. AC dust has been linked to LLE, a disease that once started is difficult to counteract.
The better location is a loose bag draped over or placed next to the return pump intake screen.

The amount definitely depends on the quantity of coral allelopathic toxins and the other animals in a tank. I've found that a cup or two of AC per every 100 gals run for 2 weeks every month does a great job. That much AC gets exhausted/used up within 2 weeks so leaving it in the system longer than that does little, if any, good.

In my 55 gallon i have a canister filter,and a hob refuge, simmer, an other equipment, but my refugium obviously does what they so, and my caniter cleans out big floating stuff and it is more of a machanical cleaner rather than a chemical cleaner, but i have a huge empty spot in the back of it, and i acctualy use the plastic scentsy wax containers (which i clean out exteremly well) and fill it with my active carbon and zeolite rock stuff blendBig smile It holds a fair amount which seems enough and in is easy acsess when time to change:)

We're running a FOWLR tank with AC in a reactor. I put in a half cup and change it every couple of weeks or or once a month.  I originally bought the WalMart cheapo stuff, but have changed over to BRS.
