The fitting ended up in the system in january and everything was fine for a while and then suddenly evrything went. So timeline was around 3 months.

don't forget to rid of the rocks for good... its no good for anyone in the future especially if it recirculates to us reefers unknowingly.

Ya and depending what you read it basically looks like the whole sytem is garbage not just the rocks.

The tank can be resealed and washed with acid to remove copper. Theoretically the rock could also be bathed in acid and stripped of copper, but it's a lot of work. Any equipment can also be cleaned. Crappy situation all around...

sorry to hear that and thanks for the learning experience! good luck with future endevours

I had read that washing the rock with acid might work. At this point time and effort doesnt really matter. to me it beats throwing out $500 of rock if i can save it.

unless it costs more to clean

Acid is cheap just depends how much a person values there time I guess.

muriatic acid is cheap. If you have the time, fill a large rubbermaid with fresh water, add half a bottle of acid, add rock. It should fizz on the surface. LEt it soak for 10 minutes or so, then remove to a new tub of RO water, and let it soak overnight. Test the RO tub for Cu the next day. You'll need to add a big box of baking soda to the acid tub to neutralize it before dumping. Wear old clothes and long rubber gloves. Do this outside and don't drip the acid on your sidewalk.

Thanks for all the help everybody.
