What's the best dry rock for walls of my 210

[ReefWhatYouSow]

I'm building a 210 gallon in wall with center overflow and I'm going to put in rock walls. Can any recommend what will work the best? I know looks can be based on preference, but how about functionality, ease of use, taking more space with spending less money?

Thanks!
Nate

a foam rockwall would be the cheapest the diy forum has a lot of tutorials

You can make a nice foam insert or do what I am about to start doing and cut pukani rock and cement then together to make a thin rock insert for my overflow.

I'm definitely planning on incorporating foam in the project. I've spoken to a few people who have already done there walls with great success. I was more wondering if a certain rock would work better based on size and price. I think cutting pieces is a great idea too.

Why did you pick Pukani?

Easy to cut, light weight very porous rock. Plus with the patterns one could easily make a wall from it.

Cool. What do you think about Marco rock for the walls?

BRS Pukani has been known to leach high levels of phosphates. Do a search in the forums but like everything, ya got to judge for yourself. I was unsure, so I went with 30 lbs of local TBSaltwater dry rock when doing my foam back wall. It broke up easy and I told Richard at TBS about the shapes I wanted and porosity. He fixed me up. So far, phosphates less than .05 (Hanna) but I am running Zeovite which works on reducing phosphate and nitrates.

Having done several of these over the years, my first choice would have been to use dry rock from a reef set up that was "live", but I did not have access to that since I just moved here and was unsure. One thing I can say is don't "over think" this, just do it!
