I'm putting together plans for a 300g reef that I'd like to include an eel in. I'm hoping to hide some pipe in the aquascape to keep the guy happy. Any reason I can't use ABS DMV piping from lowe's ( https://www.lowes.com/pd/Charlotte-Pipe-3-in-x-10-ft-ABS-DWV-Pipe/1000493205 )? I feel the black color would make it much easier to conceal. It's graded for draining/venting since it's not pressure rated, but it's also not rated for potable water, which is why I'm not sure it'll be fine.
