how to kill rock

A dip in boiling hot water will kill everything without any nasty chemicals to worry about.
 
So will a long soak in water with a bottle of hydrogen peroxide added, if you let it dry out afterwards.

Bleach works great and there is really nothing to worry about if you fully dry the rock out. The chlorine just turns into salt and if you are still worried then soak it in a tube of RODI with some Prime and you are good to go.

+1 on the bleach.Its quick and easy.

and definitely easier to rinse afterwards... :up:

The process is the issue its the repeat of the process to get all the chlorides out.

If you are really worried then add prime to your rinse water....its a de-chlorinator but as I stated before it's unnecessary.

Chlorines.... yes its more toxic by a large percentage. It contains toxic chems such as dioxins and furans... I know what prime does and my point was not to have a huge debate over it... its a proven fact that hydrogen peroxide is a much healthier base because its only water with H202 no chemicals..
 
I always have have a good day man, you must not know me very well.... no need to argue about chemistry I was only saying its more toxic to use vs. peroxide and yes it does take an extra rinse from my experiences.


Sodium Hydroxide - Caustic (or corrisive to metals yes)
Sodium Hypochlorite - Toxic and very unhealthy as I stated yesterday

Sun bleach the rock. Lay it in the sun for a week or so, scrub and rinse clean. I'm in the process of doing that now. Not due to aptasia but severe algae issues.
 
sharks... sharks with frikkin' laZer beams on their heads...

that'll get those aiptasia...
 
I usually have very specific reasons for things I do, and this applies to using hydrogen peroxide and NOT bleach (sodium hypochlorite). Why?

Bleach has many undesireable attributes, both during the 'bleaching' process and afterward.

1) During bleaching, the chlorine can cause substitution reactions with organic compounds, which are everywhere in living tissue. Some of the resulting compounds can be extremely toxic. Many of you may have heard of dioxins and PCB's, but furans are also a concern. These groups are particularly nasty, even in small quantities. I have some knowledge of these from my days in R&D.

In short, I am not a fan of playing chlorine (halogen) chemistry in my tanks.

2) As to the byproducts of bleach after drying, it does form a blend of the two salts below.

(BTW-there are [B]thousands[/B] of salts in chemistry, besides the one we eat-sodium chloride).


[B]Reactions[/B]

Sodium hypochlorite reacts with metals gradually, such as zinc, to produce the metal oxide or hydroxide:
NaClO + Zn &#8594; ZnO + NaCl

It reacts with hydrochloric acid to release chlorine gas:
NaClO + 2 HCl &#8594; Cl2 + H2O + NaCl

It reacts with other acids, such as acetic acid, to release [IMG]http://en.wikipedia.org/wiki/Hypochlorous_acid"><span style="color: #0645ad">hypochlorous acid</span></a>:
NaClO + CH3COOH &#8594; HClO + CH3COONa

[B]It decomposes when heated or <u>evaporated</u> to form <u>sodium chlorate</u> and sodium chloride:[/B]
[B]3 NaClO &#8594; <u>NaClO3</u> + 2 NaCl[/B]

In [B]reaction with hydrogen peroxide it gives off molecular oxygen[/B]:
[B]NaClO + H2O2 &#8594; H2O + NaCl + O2&#8593;[/B]

3) So, if you do use bleach, I strongly suggest that you add a little hydrogen peroxide after the bleaching and then rinsing several times, to drive the reaction to get NOTHING BUT salt (NaCl), as in the step above. Then rinse some more. Why?

4) *FYI- [B]sodium chlorate [/B](above)[B] is a nonselective herbicide[/B]. Guess what's in our corals? Yep, symbiotic algae, which are plants and can be killed very effectively by any residual sodium chlorate.

Also, FYI- there is NO hydrogen peroxide in common household bleach.

If you have a choice, why would you choose the one with greater potential hazard? Hydrogen peroxide is nothing but hydrogen and oxygen and breaks down into water and oxygen.

Hope this helps clear up any misunderstanding.
 
What did the aiptasia ever do to you man? :lol2:
But seriously, I just prop the rock up so that the aiptasia is out of the water, sprinkle with salt, lemon juice or both. 2-3 weeks later the bad stuff is gone and the good stuff is still fine...JFMFE.

I personally bleached over 500lbs of rock with nothing but good things to say about it.
