F*&% Up of epic proportion!!!

I find it surprising that a brass fitting on the ATO line can have such an effect, it really actually makes no sense unless it was actually submerged in the tank somehow allowing it to corrode faster. People use tap water in there reefs for decades and their house lines are full of copper and brass fittings. Is there another source the copper may have come from?

I can't see how a single fitting could suddenly produce toxic levels seemingly overnight.

People fill their tanks with tap water, which usually runs through a copper line... I'm suprised a fitting would cause a huge impact, maybe due to the low PH somehow?

Anyway, what was your copper reading?

[asylumdown]

Did you use Kent carbon that was subject to the recall due to copper?

[rynoe]

No kent carbon was used.

Do you use RO water? If you do, its not good.......
Do not run RO with copper or brass products, it will pit the piping very quickly and you'll have contamination.

The line has been sitting in my 50 gallon top off tank permanently. I never thought anything of it my self but right now it is the only thing that makes sense as to why everything is dead.

I'd investigate other sources, a brass fitting won't just dissolve in fresh water to the point it would become toxic.

Have you tested the fresh water in the top off container for copper? If this is the source the level of copper should be noticeably higher than what's in the tank.

The container is also used for mixing water for water changes and yes it has been confirmed as the source. From a long night of internet reading the use of DI resin to filter the water will greatly accelerate the breakdown of the metals and it can only take a few hours to become toxic.

Ya i use ro/di system for filtering and that seems to be what really makes a copper fitting worse.
