clearing tannis.
Hi everyone.
i've got bog wood in my big tank and it has
released lots of tannis,not a bad thing some would
say,and in the beginning i didn't mind it.
However i'm getting fed up with the look of it now,
as my little tank does not have any in it at all,
and looks lovely and clear,i would like
my big tank to now be clear.
My question after waffling on is this.
When i take the big bits out that are causing the tannis,
how long would you think the tank will take to clear.
many thanks.
:omg: :blueshake: it's thundering,and i'm in on my own.

adding activated carbon to your filter will absorb the tannings,

Hi Willow, I previously had the same problem with my tank. I boiled the wood a few times before putting it in the tank - and then soaked it in a large bucket of water for a couple of weeks after that.

As for the discolouration that has been left in the water - it should clear after a few waterchanges.

Oh - and we've had thunderstorms here too, last night was really spectacular!!

thanks guys,for the quick response. :D
i feel an aquascape coming on,and this will
give me the perfect opportunity to take the wood out.
re the thunder storm.I'm only brave for the children
i don't belive in inflicting my fear on to them.
however they are away for the weekend OH is
golfing,so it's just me. :(

Yeah I put mopani wood in my tank and I soaked it in hot water for about a week before it was okay to put in my tank. Every day I would drain the bucket and refill with super hot water about 2 or 3 times. I also made sure I had new carbon in my canister filter too before I put in the tank. Water has stayed very clear.

another question i have is......
i'm not sure if the carbon i have is still ok ?
is there any way to re-activate it ?
and here is a pic of both tanks.
i know it's day time,so you can't really see the tannis that much,
buy of an evening it dose not look that nice.

I don't know of a way to "reactivate carbon" but I change mine about once a month. For a normally stocked tank carbon is good for about that long. You could always remove the wood and soak it seperately like I did. If its a newer peice it will release tannins for quite awhile so you may want to take them out and soak while your tank clears up. I kept refilling the bucket with the hottest water I could get because the hot water draws the tannins out faster. I would have boiled it but couldnt find a pot big enough, lol. Beautiful tanks by the way! :-)

thanks for the reply,and tank comment. :)
i think i will take the wood out,and try the carbon
that i have,and see if it works.
looks like a busy day tomorrow :D
