Dump your old carbon and go get this...

I use an old ehiem cartridge style filter that I had. It's submersible and it hangs out in the sump. I change it out every month and am happy with it.

You also have to be very carefull not to burn your coral.

If the water is yellowish. (You can test it by putting a while card in the water to see how yellow) and the carbon is very efficient quickly, the much brighter lighting can burn your coral. So, go slowly.

Well i walked by the tank again and did a double take this morning. This has to be the best thing Ive done to the tank since the auto top off. Seriously i don't rave about products but damn this is nuts.
