I have been cyling my tank for the past 4weeks now and well to make a long story short i ran into a problem.... and i need someone that can drill a/some hole(s) on a 20gal tank (my refuge) since i have a pump in it and drainnig it into the sump i thought well what if the pumps dies... i guess i will end up with 10+gallons of water on my floor... so decided to drill it and let it empty out with gravity..

if so how long does it take and for $$........ please LMK thanks RICKY
