rocks and shells from the sea

[Kelly]

I collected some interesting rocks and some clam shells from the beach
today. I boiled them three times, changing the water each time. Should this
be enough to make them safe for the tank?

depends where you collected them and what you are afraid of

if there is a high amount of mercury or lead or copper or ...... you can boil it a zillion
times it wont make a diff

if there isnt, then you could have just added it to the tank as long as no dead stuff was
left

I am not sure if it is a co-incidence or not but 12 hours after putting in
two rocks one of mushrooms looks almost dead. Everything else seems fine,
fish, corals, cleaner crew. Is there something that would be effected first
if there is mercury, lead or copper?

I did searches on that particular beach and found a bunch of water tests
done by university students but nothing more than 2 or 3 years old. They
never mention anything toxic about the water, but not lead or copper
specifically.

treat it just like uncured LR test ammonia/nitrite/nitrate

boiling alone will kill things but not remove a significant amount of dead stuff.

after that you could test for copper. but you might just wanna wait anything out. I know
where I live there is a bay you dont wanna have anything from there come within 50ft of
your tank but not too far from the bay is ok.

3 year old data is probibly ok ish, id suspect dead tissue breaking down first
