Ok so in the summer I do a lot of prospecting. If we come across gypsum, calcite or any other calcium type rock and want to see what minerals they are holding, we will soak them in Muriatic. Often whats left over is just a sludge that we pan out to check for mineral content. I know this sounds off in left field, but the point is, I'm not sure what shape your rock will be in if left over night, you may end up with a lot less than you started with, and it will defiantly be dead. And what will you do with the acid when you are done? It would take quite a bit to soak a 135g tank worth. Myself, I think I would go with the Marco rock, with a bit of new live rock for seeding.

So after worrying I finally got to the store to buy a copper test kit after I had also used a brass fitting in my ato system and had been fully submersed for over 5 ish months. Pulled the fitting when this thread was first posted and there was definite signs of wear and fading of the original coloration and as a result of this I was scared.
Anywho I tested my RO ato system and it came up 0 as well my tank showed the same readings. Phew I think I may have dodged a bullet here. I'm off to the store now to buy a coral in celebration lol.

Glad to hear that you seem to be ok however keep a close eye on everything because most test kits that are available to us don't provide readings low enough to detect copper in small amounts and it does not take very much to be toxic for inverts and coral

YOu have a good point and the only way to be 100% sure is to put a cup of carbon runing in loop wit a small filter to make sure the water is really going through it, in a bucket with like a gallon or half a gallon of water for a day, then analyse that water. in my own test it reached .358 ppm which is 3 times the dosage to kill ich. with this test you can be 100% sur that if there is copper in the carbon the common test is going to tedect it easily.
If that come out negative, it was not copper in the carbon. If it does contain copper in large quantité like mine, then you have the culprit right there and a sample should be sent by mail to the company. Quote:

It was just a standard seachem test kit but I do not have the resources to bring my water to a lab. Edit. The seachem test kit actually test to 0.01mg/l. And seawater is .003 so yes I could have some undetected but I cannot test to the quantities that could be present. Last edited by tim the toolman; 04-22-2012 at 03:01 PM.

Sorry to hear about the crash and cause! Thanks though for posting and making us all aware of the potential disaster!
I just did a search for ANY copper fittings anywhere near yhe R/O in use.

Disposing of the acid is easy once you've added a box of baking soda to the mix. Just pour it down the drain.
