Rock Question

[GregAW]

Do you think this rock is ok for my tank? It was in a tank once before but I want to be safe and not sorry. Thanks in advance.

clean it and cycle it.

 

[GregAW]

Oh, it's clean and dead dry. Going in an already established tank so it should be ok.

bleach it for 2 months in a tub with water and a gallon of bleach. dump the water out and fill again with clean hot water and water conditioner\ declorinator. let sit for a few more days then let dry in the sun for a few days. this will get rid of all the death and make them new again. i wouldnt just put them into the tank it might send it into a cycle and spike the nitrates. they look pretty dirty and *****

You dont want to do that. Put it in a tub with water and flow for a month doing regular water changes and tests. You put it in a established tank you may end up with a cycle.

This rock came out of this tank just allowed to dry. I wasn't sure about using it since I had enough coral/live rock to replace it with. I'm not sure what this is but I think it's lava.

i got about 75 lbs of dry rock from someone on craigslist and he said it would be fine to just add it right in. i cycled it and am i happy i did. if i had not cycled it, it would have nuked my tank. better off safe than sorry.

I could bleach it for a few days but this has been my rock. I think my main concern if the rock itself could be a hazard. Like I said it was in my 55 marine tank and when I upgraded tot he 100 gallon I got enough coral rock to not need to use this but now I want to use it because of the shapes.

If it came from another tank it will have die off, etc. So I would not put in an established tank. Either cycles by itself or do one of the bleaching methods already stated.

 

[GregAW]

Ok, I'll bleach and rinse and let sun dry this week.

Once it is out of the water for that long everything dies. It becomes an ammonia factory.

I don't understand what you mean by the rock itself being possibly dangerous. Care to elaborate?

 

[GregAW]

The type of rock. I'm not sure what it is but I didn't have problems before so I'll use it. I'll bleach it for a couple of days.

Make sure it didn't come from a tank that used chemical treatment. Like copper.

Oh it came from my 55 gallon reef tank. I know it's history. :)
