Hey, I was just wondering if I have stuffed up! I was attaching my 3-d background to my 250 litre tank and I used a RTV silicone which stated on the packaging that it could be used for aquariums. But then in the fine print it says only use the clear type because the colored ones use mould inhibitors (I used the black type) should I worry and remove it all? Or is it not problem?
