Thanks.
My 90 has a sump.
The 75 pictured above is way too small, I'm trying to work out the largest tank i can fit downstairs and the 75 will be the sump for that tank when it's done. The stairwell poses a big problem. I don't feel like fabricating onsite. But that's what's gonna have to happen.
The 40b will stay the way it is. I drilled it for canisters, i suppose a sump could be retrofitted but I'm changing to injected CO2 soon and i oike the canisters because they have a limited gas exchange versus an overflow.
I don't mind cleaning canisters much in the new house. I've got 2 sinks right next to each other and a hose accessible. Way better than the bathtub at the old apartment. My wife loved that haha.
