cheers mumzy will try it out!
Ira I dont fully understand where you are coming from as silicon is removed from tanks quite often and if the chemicals were poisen to the fish or leech gases into the water wouldnt there be a lot of dead fish. There are "aquasafe" sealents you can aquire which I have so im guessing the tank uses same or similiar silicon????? and have had fish in there no problem but yea im not too sure???
