I intend to get live rocks instead of my dead ?

I intend to get live rocks instead of my dead rocks
but the there is no place in the tank ..can i replace dead rocks (in tank for 3 months) and put new live rocks instead or it may affect my biological filteration ?

 

It would affect your filtration since all the bacteria is living on your rocks. Why do you want to replace them? Base rock will eventually become live if you leave it long enough and "seed" it with a few peices of live rock.

I'd leave the rock in there, and just add a small amount of cured live rock.

 

If you've had it in the tank for 3 months, it's likely live now....

 

If the rock has been in the tank for 3 months there's a good chance it's "live" live as in covered with beneficial bacteria I don't see any possible reason for switching 3 month old base rock with "live" rock, if your tank is going good there's really no need plus with adding more live rock you stand a chance of adding bad hitchhikers imho I wouldn't switch the rock out.

 

the reason because i found the water cloudy for long time ... and my nitrates more then 20
so i am trying to do anything to lower my nitrates because water changes couldn't work.
i just added some live rocks and chaeto alge. what do you think about all that ... while i have no fishes in my 30 gal ... just anemones and some crabes ... i can't add fishes with this unstable environment

 

How long has the tank been up?

 

3 months

 

I chuckled a little but because you said you can add fish with this unstable environment, fish can take some fluxations, id be more worried about the anemone in an unstable environment, but I would just hold on the tank sounds like it's in the last stages of cycling or if not you have a source of nitrate in the tank and new live rock isn't going to change anything

 

Honestly Minajaguar, I think you are doing too much in small periods of time. You seem to be constantly messing with your systems, adding, changing, adjusting. I think all this change isn't allowing your tank to age properly. I'm not sure what new rocks are going to do to help the situation except to take liverock out of the tank which in turn will possibly cause a new mini-cycle. I'd suggest letting the new rock and chaeto do its job. Keep up with WCs, maybe get some Dr. Tims products. I'd start a thread on his sponsor page with a VERY DETAILED history including parameters of your tank. IMO, I just think you should go a little slower, lower the stocking levels and let these tanks catch up.

Good luck to ya
