It all depends on where the moon is in the 7th hour of the 8th day
I can say i abandoned my first 60 gal setup
Cause the leaks kicked my ass (it would have been so perfect) i will only mop up for a system so many times lol
I couldnt tell ya if your set up would seal as i dont want that evil on me lol
But i will say grab some silicone and thread sealant
Do not crank down on your bulk heads or they will crack in a micro line that you cant see till you filler up lol
Is your bulkhead all threaded ir is it a thread slip?
