I had the last straw happen with my oveflow box. The acrylic actually split apart and it fell down with the siphon still holding. Luckily it continued to pour into the broken part and continued to go into the sump so no flood.
I have a 240gal 8'x2'x2' tank. It's got 2 x 1200gph overflow boxes plus one 600gph box going to the sump. I have a Mag 24 and a Mag 7 pumping it back. I'm constantly re-starting the tubes for siphon. If I don't keep up with it, it overflows the dt.
Q:Would it be overkill to buy the glass-holes largest size overflow x 2 (2" bulkheads)? Or will the 1500gph 1.5" kit be enough for that size tank?
I would be buying two of each kit for either side of the tank.
Thanks,
Tom
