I would do water changes if it is real high in ammonia or
nitrite, in order to preserve the life on the rock.

Your tank is cycling...if you're seriously going to get into this hobby
one thing you need to learn up front is patience. Nothing happens
overnight.

You rock takes months to cure. You should not have changed your water at
all yet.
Do you have a protein skimmer ? While you're curing rock you should be
running a
protein skimmer 24/7 7 days a week. Smells good I bet : )

I just bought a 25gallon aquarium about a week ago and put the substate
and live rock in it. I haven't put coral and fish in and today I
suddenly found the water turned yellow!

I have pumps (Rio 800) running and using Biological filter calls.. What
do you guys think the problem come from? I changed water (about 60%
change) today but still feel water is yellow. What do you think? Shall
I do a complete water change?

Thanks!
