We are going to make some rock. Does anyone know if you can get the crushed oyster shell in Sioux Falls?

I have heard of some using a rock salt or softener salt in the rock. Then it is soaked and the salt is dissolved leaving a very porus and lightweight rock.

I made some using granulated softener salt. That worked well. I have also used macaroni which I didn't like as much. My favorite was actually using a combo of the salt and some acrylic shavings I made from drilling thru a thick piece I had laying around. Just have to make sure you get enough cement or it will be very structurally weak.

I'm not sure if I'd use oyster shells for phosphate reasons, but feed stores will have them for cheap. If I was making some, I'd use the rock salt as mentioned. That should make it porous and more natural looking.

I used oyster shells in all my DIY rock and never had any problems and it makes the rock look very real

Ive used it before too. I had a few problems, but I don't think it was the rock's fault. A lot of people use it! My oyster shells stunk when wet. May want to give it a good rinse if that's the case.

Have you weighed out the cost expense for homemade vs dry rock? I'm sure it's cheaper to make your own but is it worth the time it takes to make your own? Are there issues with the structural integrity of homemade?

I'm debating whether to do dry or have a hand at making my own too. I plan on getting a little live rock and primarily homemade/dry base rock.

I got my dry rock for about $2/lb shipped from reefcleaners.org. Really happy with the quality, even though I just use it as base rock. You can do some pretty cool stuff if you do decide to make your own however

I've made diy rock and it was a lot stronger than my live rock. Heavier too though. I still think it would take a lot of work to make rock look as natural as good base rock. I may do a combination or just make my own to hide certain things.

Benefit to making your own is "sculpting" it into what you want/need. Would undoubtedly be tough to make it look natural while still being functional though. I do like the background that people have made when done well, though.

Is it live rock Grant? If its dry rock I'd pick some up but probably be a while before I get that way...
