Lubricus you look like your in the same boat I am wondering how long my 20+ pound rock will take to cure.

...wondering how long my 20+ pound rock will take to cure.

I think it is more a matter of how solid/thick the rock is - the big one Lub shows isn't very thick really and shouldn't take much longer than any other rocks...

Im hopping that it doesn't take anymore then 3 months to cure, there's more caves and tunnels in the rock then you can see in the pic, so I hope that helps with the curing....I also hope that this one gets a bit lighter, I almost killed myself getting it down to the creek:eek1:

Seeing Lub's pic made me think of streams and creeks in my area I could stash the rock in, but wanted to ask you all.
I live in Mid-Mo, a heavily farmed area. I have a local creek that stays filled with water year round, but it abuts a corn/bean field. Should I worry about things like pesticides and fertilizers running off and polluting my rock, or are we talking so little that it would make no difference? I also can use the Missouri River - it's just a few miles away, and have a friend who lives on it, but there I am worried about silt filling my rocks.
Any input?

I'm not sure. Another thing to consider is heavy rain. I didn't think of this until now. If it rains heavy enough and the stream/creek/river floods enough, the flow could be strong enough to carry the rocks downstream. You would need to find a way to secure your treasure so it doesn't go rollign away.
 
I've thought of that, Travis - will either tie them to a log or another local rock or put them in milk crate and tie them off - maybe even attach a fishing float to help find them...
Could also use jetties to block them going downstream.

Sound good?

Still wondering about contaminates - anyone?

Im not to worried about contaminates, I think giving the rock a soak in some R/O and running some carbon should help leach-out most of the toxins, read my thread at Aquarium pros, Im sure the L/R that comes out of the ocean already comes with a list of chemicals and toxins. http://www.aquariumpros.ca/forums/showthread.php?t=20824 PS the creek that my DIY rocks are in eventually makes its way to the ocean:eek: ;) :cool:
 
My question is, do you think some of the beneficial bacteria that colonize the DIY rock in the creek might survive going from fresh to salt water?
 
Per the local newspaper.

Our main drinking water comes from a corp. of engineer project dam. For the last couple years our city has been trying to get state assistance to dredge the lake 2.5 Mil. Phosphorus is the main reason. It's naturally occurring element, but also used in fertilizer for corn and is found in livestock manure. They claim farm runoff is the biggest contributor. Then recommended changes to the water shed to mitigate continued runoff is proposed.

There is another close angular/recreation lake that has a fish no consuming warning for mercury poisoning.

These all are fed by creeks and overflow spillway. Will these kinds of things impact curing DIY rock? I am not a biologist so I couldn't say with any certainty - yes or no.

The creek my rocks are curing in feeds into the Missouri, I live about 20 miles from the headwaters. Hopefully my curing upstream of you won't slow yours down :lol:
I might go take a look at mine today, haven't seen them in a few weeks.
Re: securing rocks, I have mine in milk crates, tied together and a rope to a tree so the boxes don't wind up downstream.
 
Black rocks?

Black rocks?

Hi, I would love to make black rocks, in memory of my trips to Costa Rica. Would it be possible to mold the salt-ciment rock in Tahitian Moon sand, or rub the rock with the black sand while wet? Would the sand stick permanently to the rock? I would use lava rocks but they are too pricy and may not be safe to in SW.

You might think, "in few months they will be covered with coraline so there is no point." I will have a rock pointing out of the water so I want a black lava-like rock :D .
 
What about food coloring...or cement dyes like they do for sidewalks and driveways...gotta have black...

Keep us posted.

Great thread

No, the bacteria will not survive. I believe reverse osmosis kills them. It's been a long time since I've been in microbiology though. My terminology could be wrong.

But my rocks are in creek water not R/O
 
It's still freshwater. What happens when you put a single cellular organism from freshwater to saltwater, it draws the water out of the cell causing it to burst and die.

Travis, Id realy like to thank you for posting this thread, do you have any idea how much money you've saved me, money that can be spent now on better equipment.

I do have a question about making large DIY rock, do you think 3 months curing time is enuf?
 
It all depends my friend. Just keep testing the water for pH. Time varies. I understand how much money was saved. I've saved myself almost $1000 through various fish tanks.
