90 gallon to drill or not to drill?

[katguevara]

Has anyone has success with a 90 gallon tank that doesn't have a sump? I have one that I'm thinking about setting up. It's not drilled but I do have the option of having it done. I just want to see if there was anyone out there that has success without having to drill. I've heard of overflows and can't afford to ruin our floors. I'm a newbie so bare with me if I don't understand and ask lots of questions! [emoji1]

in my opinion over flows are the way to go... personally i like the overflows that allow for a bean animal style this gives you two extra pipes just in case your main drain pipe gets clogged... i like drilled tanks but i have a 40 that i used an over flow box and it went well...
