Anyone ever tried it? There are a bunch of videos on youtube. Pretty much mix Portland cement with some perlite, or oyster shells (there's a few f offer en ways) and put in a mold you made out of sand, Let harden and cure.

Haven't tried it but I did research it when I first set up my tank. I just didn't feel as though I'd get perfect results and I'm picky about how my tank looks. So I decided against it.

I have, it is a pita.... curing time takes forever! you need to dissolve the salt you have built into the rock and this takes a wile, not to mention it is heavy to say the least.
but if you do make a couple pieces (dont laugh) the fastest way to cure it is to put it in the back of your toilet. when you flush it rinses the rock after about a month you can cure it for the fishtank

Would I have to cure the "rock" is salt water? That would be the only kicker for me, I'm. Not going to make multiple water changes with salt water for something I may throw away

I've thought a lot about building my own rocks over the years. The idea of being able to create a solid structure that wouldn't fall ver or collapse is tempting. But the issues of curing the cement rock so it doesn't leach out stuff into the water along with getting the pore structure natural looking has always deterred me. At some point I'll give it a try though.

I know this takes away the savings and diy aspect but you can get custom built artificial rock structures on cultivated reef? They're supposed to be porous and light weight if I remember correctly? Idk the prices..

Is there any type of purple paint that would be safe to use on this fake rock?

Not going to make multiple water changes with salt water for something I may throw away I'm pretty sure you can cure the rock in any flowing water? I saw videos of people doing it in streams in their back yard. |

in a bucket you would need lots of flow and to fill and drain multiple times for a couple months this is to dissolve the salt in the rock you use to make it porous along with wash away any powders left behind from the cement. like I said before I have seen threads where people but the rock in the back section of their toilet...

So I made a few pieces of "rock" 3 part oyster shells, 2 Part cement, 1 part sand. You think it would work to cure rock in a pond? Like if I put it in pond today and pulled out late November early december.... Idk how legal it is, but everything is legal unless you get caught.....

Nothing illegal about it. Most ponds are pretty muddy from silt and decaying matter though so it may not be the best place for it. Pretty sure most people say to put it in flowing water like a stream to help flush out and disolve the salt and any dust. I may be wrong though.

It's all rocks in front of my camp, so i was thinking if putting it o the rocks, not the mud. I do have a stream I could put it In but hardly flows

Ah, it may take longer to cure in water that's not flowing, other than that it should work the same I would think.
