Carbon in the marine tank...

[Ken]

Hi, carbon is only effective if you have the water running through it. What would be nice is a reactor to place the carbon in will force the water through it. Placed in the sump, the water tends to go around the carbon making it less effective unless you channel the water in a way where the water will flow through it completely. Canisiter filters are another option if you place enough carbon packed in the basket, again allowing water through it and not around it. Regards Ken
