I dunno ... I was once advised against using ABS on reef tanks. I suppose you can use the stuff, but ... one question for food for thought: if something is acceptable for potable water, then logically it ought to be acceptable for your reef tank (or other aquariums for that matter). I guess the question you need to answer is: If it isn't acceptable for potable water, is it thus transitively not acceptable for use on your aquarium? The answer to that question, is up to you, and presumably should be based on things like "why is this stuff not acceptable for potable water" and if the answer to that is "I don't know" then you'll have to move on to things like "well how comfortable am I with risk?"
As for ABS ... I don't know if it's not rated for potable on account that it's not rated for the typical pressures of delivery, or if it's because it's not inert. Maybe it's OK for freshwater ... ??
