Hi all,
I recently got my indorr pond up and running and after a few days with its inhabitant in I discovered that the water was starting to change dark red. At first I thought this was due to the peat I had put in. But, today I can see that it was caused by the piece of plywood that I was using to cover one half of it. It seems like the condensation on the wood has caused it to leach out a dye into the water. The water is quiet red now and i have started to do graduall water changes. My fish doesnt seem too bothered yet, but obviously I'm a bit worried. If I thought it was just the natural pigmentation of the wood leaching out I wouldnt worry either but this is clearly some kind of wood preservative or stain that has gone into the pond.
Any ideas how i should Proceed? I have started changes as said before but If anyone has any other ideas, pls let me know. Maybe I shouldnt worry too much. I have removed the sheet of ply and the fish isnt dead yet!

Thanks
jason

At this stage, there's not much else you can do besides continuing with what you are already doing.

Buy a pantyhose, fill it up with activated carbon, tie it up so the carbon won't spil.
Rinse the 'carbonstocking' under a fast flow of hot water, then colder; put it in your pond near the filter or pump.
In your case a nice big box (a few liters or say, 2,5 kg) of a good brand should fix it.
Carbon will swipe up any large molecules and all kinds of metallic ions, so chances of toxics staying are slim.

it might be smart to remove the peat while doing this (or the carbon will get that too) and exchanging the carbon with the peat in a week or so.
