craby November 25, 2004 Share November 25, 2004 I want to make a mini bulkhead out of 1/2" PVC pipe in the side of a 2 gal nano that drains into a 5 gal sump which returns back to the 2 gal nano via a small pump. Does anyone know if the glass bits sold at HD can be used for fishheadamania maximas drilled holes so small in glass non comercial like, or do we have to go to TRT to get such a small hole drilled?

ctreptow November 25, 2004 Share November 25, 2004 I use a dremel with the Diamond tip bit. I just punch a small hole in the glass the grind around until it's the size I need. Use water to keep the bit cool. should work for ya. Chris Link to comment Share on other sites More sharing options...
traveller7 November 25, 2004 Share November 25, 2004 Slow flow gets slower in time due to grow of tube worms, tunicates, sponges, etc. etc. IMHO, even on a tiny tank, you want a much larger hole. Good luck. Link to comment Share on other sites More sharing options...
