I've used Black Diamond for years and it does a great job. This is the best price I've seen for the product.

Great price on carbon, very happy with purchase and retailer.

I looked at several shops and online stores. Best prices and free shipping over $49. I'm going to be a regular customer at Pet Mountain.

I mix about 1/2 - 3/4 of a cup of this activated carbon with the clumping, clay litter when I change out the litter box and my house NEVER smells bad. I've even taken the cats on road trips in the cab of our truck with the litter box sitting right next to me...no stink! Great stuff! Just be sure and use a large scoop to clean your box so you don't take the carbon out when you clean.

Works great; I use a lot to help the keep my water in my tanks clear.

The big box stores wanted $11.99 for 10oz, and this was super cheap in comparison! It does the trick as far as what it's supposed to do. I will be using this stuff from now on!

I have always used Marineland black carbon in my Fluval 304 filter. It lasts for months and does an outstanding job at keeping my fresh water clean.

Unlike cheap charcoal carbons, this high quality carbon has much less dust. The quality is apparent as well, in the odor and stain control in tank. Over the past decade, I've tried virtually all the Carbon brands on the market, and have found Marineland carbon to be the best. I now buy in 3.65L container to save extra money! This is an excellent alternative to purchasing expensive pre-packaged carbon media. Simply buy a nylon bag (usually less than a buck!) and fill with Carbon. The bag can be re-used. If you're using the filter cartridges in the Hang on Tank type filters, you can also open the top of the cartridges and pour out the old carbon and re-fill with new. This helps save money, and with good cleaning, you can re-use the cartridges a few times.

The best, longest lasting carbon PERIOD!

I used to use the cheap stuff in the milk carton and it was always really dirty. Black Diamond has always had much less dust. The price is excellent as well!

Since I switched to Black Diamond Activated Carbon by Marineland / Aquaria my tanks have been clearer and cleaner and I havn't lost even one fry. Great Product.

I'm not an aquarium guru but I have a 10gal freshwater tank at my desk. Despite the regular filter on it - and changing regularly, it would still get a little 'aromatic' from time to time. So I add some of the charcoal in addition to the filter and it seems to make the difference.
