DIY Rocks
I know there are a few in the community that have made DIY rocks. I have also read a lot of threads on the subject and it seems that there is quite a few ways to go about it.
How is the rock now, that it has been in your tanks for a while? Is it flacking? Would you do it again? What recipe seemed to work the best? How long did it take to cure? I read that someone used grout instead of portland cement. Hopefully I will be doing my own rock over the holiday.

I've had a couple pieces in since I started my tank in august. Now it looks almost just like any other rock in the tank. I can still tell the difference, but my mom couldn't Here's what I've found:
It flaked in the beginning, but not too badly. Before I put it in the tank, I took a wooden dowel and lightly beat the rock and rinsed it and stuff. Gets most of the stuff off. Yes I would do it again. I have 1 big rock made for the 70g, and I will be doing some more in a couple weeks. I don't remember my recipe exactly. I used cement, perlite, crushed oyster shell, and a little sand. I just used plain silica sand, didn't bother spending big bucks on aragonite. I used rapid-setting cement. I took it out after a day and cured it kind of an odd way. I didn't check on it regularly since i wasn't in a hurry, but it was out of the water for a couple weeks and in the water for a couple...maybe less. I think total it was 3-4 weeks. I am going to try baking rocks next time to quicken the cure. I've heard it can make it take as little as a week. The big one I just did I boiled and it has been soaking a week. It was also sitting outside for about a month lol. I haven't used grout, but I use "rapidset" brand cement. It actually has big rocks in it, but I sifted it out easily. It hardens quickly and makes a nice whitish-grayish color...much better than standard portland. I like using Perlite in the mix, but it is tricky to get the mixture right. if you want to try some, I have a 20cu ft bag I could pull some from and let you try it out. If you use crushed oyster shell, don't use a lot. Too much and you can cut your hands up pretty easily handling the rocks. |

Mine has been in the tank since May 5, 2007. No appreciable disintegration in that time, and it looks like live rock. I used white cement, crushed coral, snail shells, rock salt (grains, not pellets) and crushed styrofoam packing peanuts. I cured mine in water spiked with muriatic acid for 3 weeks.
Using a polymer modified grout is an interesting idea, but I'd read the MDS sheets carefully to make sure there are no unwanted/leachable chemicals in it (ie nitrates, phosphates, borates) Denny, let me know when you are planning to make some, and if I'm able to, I'll gladly come and give you a hand and demonstrate the forming/molding method I used.

mine is still sitting in water being cured. alot of work, but it was fun.
i used the gray cement (cant find the white stuff), crush coral, rubble broken from live rocks, dried out live sand, oyster shells, and bottled foam. cant really tell that there is cement used. mostly covered with rubble rock and sand. i'll take some pics when i get home... |

I didn't use any salt in my mixes. I just didn't really want to deal with trying to make it leech out. But casting the rocks in a salt mold works really well. Sand is kind of a pain, but I can see a use for it. I prefer salt.

Would baking it be kinda risky I mean is there is a water bubble or air pocket caught in there somwhere it might go boom !! Or am I'm over reacting ??

I've been using the same rock i made back in 2004. Most people don't know any difference. Admittedly its not the most beautiful rock on the planet but it serves its purpose. I used the basic garf recipe only adding more crushed coral and a little less sand. It made the rocks really porous and light.
I like the sand casting, something to think about is using clumps of wet sand for your hollows. It stays clumped during the casting and makes for better openings. How ever you make it always check your ph in your rinse water. If its really off the scale allow it to water cure a little longer.

There was an RC member who used the grout and it worked great also he did check the MDS and there were no issues of leachable chemicals. But you do have to watch for the grout that has a mold deterrent. The cool thing about the grout is that you can get it in different colors. I would love to do mine in a deep brown color.

I am thinking of setting up a date in December or January to have a rock making party. Possibly we could split the cost for the people who want to make rock. I have a large yard that we can cure the rock in for the time it takes. Who wants to come over and what date do you think we should do this on? I live in North Phoenix 51 and 101 area. We could also do a barbecue and maby some coral trading

lets get a date and people firmed up. Then we can make a list of what people are bringing. IE food and rock making supplies.
Don't forget the 80% rule. 80% of the people that say they will come, won't
