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

Here in the Netherlands playsand is not as safe as they thought it was.. most of it contains asbestos and multiple brands are being recalled for it.

And just like the silica dust found in play sand, as long as your fish aren’t inhaling the dust, the risk factor is zero.
And what a shocker that the recalled products come from China.

Key Details of the Recall:

• Affected Items: Colored sand in, for example, the Giant Box of Craft(Hobbycraft), Sand Building Castle Set, and Magic Sand Tubs.
• Origin: The contaminated products were manufactured in China.
• Action Required: If you possess these products, stop using them immediately. Do not dispose of them in regular household waste. Return them to the place of purchase for a full refund.
• Safety Advice: Keep the sand damp to avoid generating dust, seal it in plastic bags, and keep it out of reach of children.
• Risk Level: While any asbestos exposure is concerning, health authorities indicate the immediate risk of inhalation from the sand is generally low, but it should still be treated as dangerous.
