Thanks! If I'm running a BeanAnimal system, from what I can tell, I'd be just as fine making my own overflow box, wouldn't I? Literally all it looks like I'd need is somewhere to house the PVC & all of that piping would do the actual work.
If you'd be willing to let me borrow that to drill, I'd be super appreciative I don't have any qualms about drilling my tank, worst case scenario is it shatters everywhere & I have to grab a brand new one at PetCo's $1 per gallon sale. I'd definitely love to see your setup too, it's hard to conceptually picture a lot of these things just based off of articles & drawings.
If you have the requisite DIY skills, you can totally build the box for the BA setup. Just let me know whenever you want to drill the tank and you're more than welcome to borrow the drill bit. If you don't have any plans this weekend, shoot me a PM and we can figure out a time for you to come check out my setup and get the bit.
