Thanks Joe, since your here
I'm just kicking around a new 8ft build to replace an aging standard 180. I've never designed a tank as far as number of holes, placement etc.The current tank has 2 hob overflows, one one in each back corner. They each have a single 1.5" drain. No emergency drain on either. I have a single 1"return. My sump is a repurposed 125g and is in my basement. Ideally if I do this would be to use the existing sump and just tie into the existing plumbing. Is this something you would even recommend? I know almost everyone has emergency drains but to be honest with two 1.5" drains and a single 1" return I'm not sure they are needed. I just don't know if I'm up to completely replumbing the entire system especially since it requires drilling more holes through the floor. I already have 2 holes in the dining room where I pulled a 150g that shared the basement sump
I don't chase 10x turnover and the drains and return are more for mechanical filtration and surface agitation. I have a quite a bit of flow in tank using power heads. Thanks
