Black ABS use in the aquarium

[fishguy1978]

I have several pieces of black ABS that are 2in or larger that I would like to use as drain pipe for my 220g. I have always used sc40 PVC because it’s safe and ABS isn’t.
Is Black ABS really unsafe for use? I have searched the internet that never lies and am still unsure.

I have used miles of ABS pipe and hundreds of assorted ABS fittings in my tanks over the past 50+ years. Never encountered any sort of problems, with any of the many species of FW fish I've kept. I usually allow the solvent cement used with ABS to dry and cure overnight just to be safe. Many of the tanks that used ABS in sump plumbing, as hidey-holes or caves, etc. were in continuous use for many years.

Disclaimer: I change water a lot, and often. Is it possible that a large quantity of ABS in constant contact with the water in a small system which rarely or never sees a water change might conceivably leach enough of some harmful substance to be a concern? Maybe; who knows? In a situation like that, I still think that you would encounter other problems commonly described as "old-tank syndrome"...which should really be called "old-water syndrome"...long before some esoteric ABS juice became an issue.

I intend to continue using the stuff without a care in the world.

I have used ABS for years & years. Just don’t drink the tank water.

FYI….. play sand is safe too, except in California.

Lol, just because something is safe...doesn't mean that it isn't a PITA as well...

Nothing is safe in California
