Dry Pikani bleach than acid bath

[Bblinks]

Cool thanks guys

[nbreau]

Not looking to hijack the thread but could you please explain the purpose behind this process ? Is it necessary or does it simply speed up the cycle time ? I'm setting up a 90 gallon and ordering about 60lbs from Eli and wondering if I can simply let it cycle in the new take over a few months with seed rock or should I be doing this process prior ?

thanks,
Nick.

Acid dipping is necessary due to the left over organics in the rock which will cause a phosphate spike even long after the tank has been cycled. lots of people run into algae problem with there newly set up tank and ultimately give up after months of battling green hair algae (gha) with no success not knowing that it would've been prevented simply by curing your rock prior to placing them in to your tank. There are a few ways of curing your rock and one of them is to acid dip them then run them in a bin with saltwater, heater and pump for a month or two before placing them in your tank or some will skip the acid dipping part and just do the latter but thats all personal preference. There are a hundred ways to skin the cat but if you are getting dry rock especially pukani, you will need to do this.

If I took the rock out of the acid too soon is it essentially a waste of time?

Between the bleach and then acid I can see that a lot of crap came off the rocks, however there is still discoloration on the rocks.

Second, the rocks still have a bleach smell to them. They have been out of water for 2 days, but are wet still. I have a feeling they absorbed some of the bleach.

any idea how to make sure I get all of it out? I assume it will give me some issue if I try and cycle the rock with the bleach smell.

Easto, if that is your pukani after your acid bath then you did not do it long enough my friend. All that dark crud should bbe gone.

I figured that much. I was nervous that it was possible to leave it in too long so I took it out within 10 minutes. My goal was to get rid of all the crud off the rocks so I can cycle them in my tank.

It's way too cold out now to be screwing around with water outside.

Best thing to do now? Cure it in a container in the basement?

I guess other people can learn from this

Basically if I don't change out my gfo reactor I will see a cycle?

Seems odd....

Yah agreed reefwars. Easto if you have any questions about the rock why dont you talk to Eli. He knows that stuff really well. Eli's tank is pretty friggin sweet and he never did the bleach or acid

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include ammonification, nitrification, and denitrification. This means fish can swim in water without dying. This has nothing to do with curing your rocks.

Now, why do you want to "cure" your rock...

Rock, especially Calcium Carbonate (live rock) that has been in water with inorganic phosphate will adsorb phosphate, the depth and level of contamination will depend on a varietty of factors for example, length of time of exposure, properties of the carbonate structure and concentration of exposure.

Pukani rock is essentially dried Calcium Carbonate that once had organic forms living on it but now has perished by the harvest and drying process leaving phosphate molecule associated with a carbon-based molecule as in plants or animals. When you acid dip them, you are removing all those potential dead organic matters to eliminate the "new tank syndrome" where green hair algae can establish and feed off decaying organic matter. Through perseverance, one might be able to overcome this stage by manually removing gha, heavy water changes with combination of GFO and eventually at some point an equilibrium will establish and phosphate leaving the rock will equal phosphate entering, but this is not for the fainted heart, most will shut down.

If we remove the phosphate from the water column then it will continue to leave the rock, the length of time this takes is dependent on the factors described above, however, at some point the rock will low enough in phosphates, and if you provide other essential parameters including enough good light, watermovement, correct temperaure, correct salinity and a balanced supply of calcium and carbonate you will get the calcerous growth most reefers aim for (bascically phosphate inhibits biological and abiotic precipitation of calcium carbonate).

Back to your question, no, it will not see a cycle if you don't change out your gfo.
