    I've had this bin set up for about a month now and still the water is quite yellow, I don't want to use this for my w.c.! I set this up because I have a planted tank and the tap water here can be very alkaline and goes over ph8 at times! The setup:

    Steps taken:
    1) ~1 gallon of Shamrock peat moss in a cotton pillow case was left to soak in ~9.5 gallons of water for two weeks. An airstone was used underneath to agitate the moss.
    2) Tested water and it was slightly acidic at 6.8ph and the water had plenty of tannins in it. Removed the peat moss (made a big mess) and the airstone at this stage.
    3) Setup a spare JBL greenline ^ to clear the water and remove any debris.
    4) Added carbon between the filter pads and this was done on 20th (Wednesday).

    Water on 13th April: [​IMG]

    Water today (7.2ph due to less tannins?) ((doctor my sample is ready! :O))

    Carbon I used: [​IMG]

    Can someone please tell me where I've gone wrong? Not sure if it's the carbon type (granule vs pad), or how much peat moss I used? etc. Thanks!

    The carbon could be saturated and unable to remove more tannins. Another possibility is that the color is due to small microscopic bits of moss that the carbon will not remove. You should try to run through a micron filter or filter floss to try and remove particles.

    Adding zeolite might be helping

    Thanks for the tips everyone will try these out! I think something like this always needs a bit of fine tuning before you get it down to a science.

    Might also want to look into Seachem's Purigen instead of carbon?

    Also the type of carbon your picture shows is not the best type of carbon granule to filter water.. :) Though it is often sold in LFS but it's more suited for air filter than water filter.. The chunks are to big and the water is to dense to effectively pass through the carbon pores. For filtering water the lighter version carbon has smaller grained chips and is much more effective and lasts much longer. Look for example at the JBL Carbomec Activ this is the most effective shape. size and type of active carbon for water filtering.. Don't waist your money on the big chunked round pellets.. :)

    Well my other solution is just break the carbon chunk...after that wash it to remove the excess carbon dust.

    Not realy a solution, it's the type of carbon, it is pretty hard and has a very small pore structure, breaking it in smaller chunks doesn't make it more effective..

    See this video, it has a nice explaination about how it works and which types works best.. :)

    Thanks guys and Marcel great video. 1/4 light lost to yellow water! Clear water is a must for a high tech planted! I wonder how available ROX carbon is.. I mean until now I didn't even know there were different types lol

    Sounds like you should be asking more questions and quality research here on ASW.
