Adding more rock

[allof fish]

I want to add more rock to my system and my options are live dry rock or live rock. I thought about the potential of adding purple dry rock for the natural look but figure it was leach phosphates and screw up entire system right? Cured dry rock would be cheaper than live rock so might be best option. Is that something I can add all at once and won’t mess tank and parameters up or a little at a time. Assuming adding live rock won’t affect anything. Just want to add rock safely without messing up biological filtration and parameters. Thanks for advice

By far the best and safest is real ocean live rock. 2nd, and just as good, established live rock from a mature tank.

Everything else will go through some sort of ugly stage.

In an established system it’s best to use live rock or cycle dry rock BEFORE putting it in your tank. As mentioned above anything else will cause you issues.
