more rock/less water volume

Running a 55 gallon tank. I have about 75lbs of live rock which has taken nicely and has plenty of coraline algae starting to grow. I am starting into corals, just small ones like zoas/shrooms and easy stuff. I wanted to put some base rock into my tank to raise the amount of rock I have in the aquarium, but this will lower my total water volume.

Is it better to have more water volume or more rock surface? I am doing a 10gallon water change bi-weekly. I don't want to do anymore frequent water changes nor do I want to up the amount. What is better? More water volume or more "dead" rock that will eventually change to live rock in a couple of months?

 

You should most likely have more than enough rock for the nitrogen cycle. More water means a more stable environment for coral growth. It gives you more room for error. I would estimate with your 10 gallon water change that you are doing about a 33% water change.

 

I have four large rocks as the base of my tank and then 3 other medium sized rocks building up from the larger ones. I guess I wanted to do more aquascaping and build rock up my tank closer to the lights.

thanks 2in10. I think you've commented on everyone of my questions i have ever had. K+ to you sir. Thank you

 

did you count the water in your total system? my 125 DT has a 20gal fuge, 80 gal sump and 60 gal sump so the actual water displacement percentage is to your whole system not just the tank for stability
