I have a 300g acrylic tank and i dropped the drill inside, a small chunk about 1/2 in chipped out the botton, (not all the way threw) but there is a small crack at the bottom of the chunk that is leaking. Obviuosly this tank is empty i was doing a water test thats when i noticed it leaking. WILL weld-on solve this issue? Silicone? Anyone ever fix a issue like this??? please help...
