Cycling of your new live Rocks

[Junwei]

I use high concentration hydrogen peroxide to kill everything in live rock bought from LFS. Bleach didn't work too well for me as it was too slow.

After soaking it will there be any bacteria left??? I doubt so ya...

No bacteria left. Kills everything. Must get from overseas. Controlled item.

You got it from amazon?

[Junwei]

Yup. Btw the peroxide also dissolves the organic matter holding the live rock together. So don't put the live rock into the peroxide solution for too long. 2 days shld do it. Or the rock starts crumbling.

Hydrogen Peroxide can be purchased from Guardian Pharmacy, in 100ml or 500ml bottles.  Depending on stock.

Soaking LR in diluted concentration of Hydrogen Peroxide for 3-5 mins is enough to kill algae and usually enough to force worms & crabs out.  Soaking for 2 days.....that's a bit extreme.

[Junwei]

Oh yes. I didn't mention. My goal was not just to kill the organisms. It is also to bleach the rock to make it look cleaner. Just my personal preference.

[chercm]

just to check is it to pour on the surface of the rocks or need to pour into the pail and put the rocks in ?

[Junwei]

Doesn't matter really. But what I do is pour directly into the rock so it absorbs all the peroxide. Theb add water to dilute. It fizzes like mad this way.

pour directly after which you need to soak it with fresh water for how long or just place back into the tank?

[Junwei]

thats the best thing abt hydrogen peroxide.... it is non-toxic... the by products are oxygen and water. I washed mine under running tap, soaked it for 1 hr and it was ready to be put into tank with livestock. Any minute traces of leftover product on the rock is converted to oxygen.

If you buy 3% concentration, use it undiluted if possible for quick results!

the hydrogen peroxide that you refer to is it this one : http://www.guardian.com.sg/hydrogen-peroxide-3-solution-500ml/p/100303 ?

I have only tried undiluted 35 percent hydrogen peroxide. You could use the guardian 3 percent but it might take longer.

Gd morning reefers,

I recently set up my 5 ft tank and was keen to cycle with the live prawn method, however the tank maker said it was not necessary and proposed dosing microbacter7 and biofuel daily for 7 days and start measuring the water parameters. 

currently at 7th day, the reading is such:

Salinity 1.028
NO3 25
PO4 0.03
CA 500
MG 1500
KH 8.0

Numbers look too good to be true for a week of cycling. I am not in a hurry to put in livestock, so am ok to wait on. However, will the reading change as a wait on? Is the cycling proper?

Did you check the ammonia level ? Monitoring the ammonia level is the best and correct way to check if the cycling process has been completed.

Yes , some bacteria products is known to speed up the cycling process
