    Hello everyone,

    I recently redecorated my 90g tank and added 3 large pieces of mopani wood. They've discolored my water significantly... And although my South American cichlids are enjoying the tannins, I am not.

    I added a bag of activated carbon to the filter a few days ago and it hasn't cleared up much, so I'm thinking about trying a bag of Purigen instead. The reviews seem really great. Any opinions or advice on the stuff? I normally don't even run carbon in my tanks, I'm chemical filtration-illiterate, if you will. Thanks in advance!

    Did you soak them in hot water before you added them to the tank?

    Followed the instructions and soaked them, but I knew if I waited to keep soaking them until they stopped leaching it would be weeks before they were ready. I'm too impatient for that, haha!

    There's your problem then haha. You could try Purigen and see if it would work. I heard activated carbon would work too, but it didn't do much for me either. I haven't tried Purigen as I have a planted tank now, but I decided just to roll with the tannins. I picked fish that preferred tannin-stained water, and they all seem happy!

    It would probably be months... I once soaked a large piece of Mopani wood for almost 3 months, draining and refilling the tank I was soaking it in with hot water every day, and the water was dark with tannins within hours every time. At the end, I was filling it with tank-temp water and still the water turned very dark within hours. I ended up selling it.

    Exactly... I wasn't willing to wait that long. Or deal with that everyday. Doing this and finding a way to keep the water clear seemed more practical to me!
