Hey guys tonight my tank is being drilled ready for sump, I have a question that's needs awnsering, Should I be drilling the side of the bottom? The tank is 6x2x2 (12mm thick glass), my friend (who is drilling for me) has drilled his tank and he has drilled the bottom of his, I have seen some people drilling the sides of there tanks instead though. What's should I do? + any tips on drilling would be greatly appreiated!!! Thanks for any info or tips given
