    Hey guys, can you guys please give me some guidelines as to how you people are using activated carbon?

    I just bought Brightwell's Carbonit-P, is it a good product?

    Very good product, Jinx. Activated Carbon is something that should be replaced regularly. It is to "polish" the water, and remove unwanted toxins as well as toxins from chemical war-fare (between corals and anemone's) in the tank....

    AC makes the tank's water look EXTRA crystal clear..... BUT, AC can also leach phosphates - therefor - NOT a good idea to leave it there long-term.

    If you want, you can use it constantly. BUT, don't keep it longer than 4 to 6 weeks in your tanks sump, mate.......

    If I keep it in say for two weeks, will it remove most of my supplements?Should I dose everything as normal?

    It should not remove ANYTHING you add to the tank, Jinx!

    I'm just asking because I heard that carbon removes supplements.

    No Jinx. Carbon does not remove supplements. The only "chemical" that activated carbon can also remove, is perhaps iodine..... nothing else that I know of.

    What about trace elements?

    In the 5 years that I have kept marines, Jinx - I cannot say that I have ever had this issue (or any lifestock problems, because of trace elements being removed).

    Remember - in the 4 to 6 weeks, you would have done AT LEAST one to 3 water changes (depending on your frequency of doing water changes) - which would MOST DEFINITELY have replaced ALL chemical trace elements in your tank's water. :)

    I would add to boil somne RO water and soak the carbon for twenty four hours in the boiled water. This helps to remove a lott of phosphates from the carbon

    @Jinx To test if the carbon you are using is leaching PO4. Take some PO4 free tank water or RO/DI water and using a good quality test kit test the water. It should be <0.01. Now add a few granules of the Carbon to the test vilal. If you see a blue streak coming off the carbon granuls you know the it is leaching PO4. Some carbons take longer to leach the PO4 than others so leave the test for about an 30min to a hour to see if it turns blue. This way you will know the quality of the carbon you are using and if it is PO4 fee.

    o

    my understanding of AC is that water has to PASS through it in order to have any affect

    therefore, just letting it soak is not going to do much..

    The soaking in the RO water is just to remove the excess phosphates. Most carbons are high in phosphates and Rowacarbon is the onlky brand that guarantees it's phosphate content.

    But to answer your question water has to pass through carbon or it to adsorb things

    tony, won't boiling water damage the structure of the carbon and make it less efective?
