Yah it sucks, but if your in this hobby you have to expect to get wet once in a while
I have a piece of 3/4" this time just to be sure. Should have all five bulkhead holes finished tonight and it siliconed back in. Man, drilling 3/4" is a lot of work! The hawks are doing fine in the sump and the other fish are happily exploring the extra rock in the 120. Once it's ready for water I think I will do a big change on the 120 and use it in the 75. My storage tank is only 35 gallon so I'll be busy making fresh for the next couple of days.
