Bleach question

[jfl14609]

I have a small amount of live rock that's been sitting in saltwater for a while I decided its time to bleach it can I add bleach right to the saltwater or does it need to be freshwater

I used tap water for the bleach. would [really, really really] recommend outside. Used 1G bleach to 10G bleach per Cully's rock re-incarnation thread.

thats exactly how i normally do it i was just curious if it makes a difference if its saltwater as its already in it

Tough to say. Seawater is a pretty saturated solution, but H2CLO4 is already dissolved in water. Give it a shot?

There's lot's of stuff in the salt water for it to react with and it may loose some strength oxidizing organics and acids or produce some toxic stuff. I'd watch out for chlorine gas fumes if ammonia levels are significant or become significant during the process.. I've never done it that way; always used freshwater.

Here's a link fyi:

I would just swap out to freshwater to be safe.

I actually just swapped the water out. I kind of planned on doing that I was just wondering if it made a difference

I think that's a safer course.

Perhaps dilution in the salt water would have been be enough to make bleach ok to use there but maybe not. The ammonia/bleach mix thing is a little scary; in some cases according to the link I posted; the chloramine gas is bad but even worse is the potential for explosive hydrazine to form( that's jet fuel btw.).
Then I wouldn't know what compounds the bleach mix would create in tank water and how much bad stuff might stick around on the rock.

chlorine or chloramine gas = not good

I remember someone cleaning out the muriatic acid piping, and then proceeding to clean the sodium hypochlorite piping, mixing the two in a giant concrete tank. Yeah... definitely not something I would recommend.

FINALLY I get to correct Tom!!! It's ROCKET fuel!!

Thanks Steve. I should have looked it up . I was just winging it. Either way it's :blown:

Jets? Rockets? Winging it? What, did I click on the aeronautical forum by accident?
