I just got a AGA 65g RR tank for my gf as a christmas present. Its early but gives me time to build the canopy and getting the lighting. Already have the stand being used on her existing 24AP. I had made a ghetto style PVC pipe overflow for her 24AP going to the sump. On my 125g I cut out the overflow on the back top of the tank. Never really liked the bottom overflows in case of accidents. This tank has the overflow holes already cut out on the bottom so I have no choice but to use them. Never had these experince so I know this question has been asked before but if you can tell me the name I can look it up. What kind of overflow do I use? The tank uses a Megaflow Overflow. I just need to make the PVC piping behind it. It has two opening on the bottom. Wanted to use both as overflows (one as overflow and the other one as emergency in case ) and run the return line behind and over the tank. Let me know if this is a good idea? Thanks everyone
