This is going to be a progressive thread i will keep bumped with information on the subject, so keep looking, and keep the criticism coming, cause i eat it up!

=-=-=-=-=-My Mixture-=-=-=-=-=

I begin with the following ingredients:

Note : PPB = Portion Per Batch

*****************************************
* (2) 92.5 lbs. bag of Portland White Cement I/II *
*****************************************
- Price : $19.95/bag ($43.19 Total After Tax)
- Location: Local hardware store (ex: Home Depot)
- PPB: 1
- Total Weight: 185 lbs.

**********************************************

**********************************************
- Price : $6.20/bag ($24.80 Total - Tax Free)
- Location: Local Feed Store (ex: Manvel Feed Supply)
- PPB: 4
- Total Weight: 200 lbs.

Note: If you live in an urban area, reach for the yellow

call around and ask for crushed oyster shell chicken
feed (its a supplement added for digestion).

Note: This stuff is dirt cheap (no pun intended), and i find
it to be cleaner than the play sand you find at home
depot for the simple reason that its from a specialty
store, which "usually" means higher quality product

people also like to add argonite sand, or sea shells from the beach to thier mixtures, choose your mixture to your taste, not mine. This is the mixture i used because i wanted durability, and the most porous mixture i could acheive.

======================
= Total Price: $138.82 =
= Total Lbs of DIY LR: 385 lbs =
= Price/Lb of DIY LR: $0.36/Lb =
======================

--At 3.25/Lb at your LFS 385 lbs of LR (uncured) would run you
approximately $1251.25

--I HIGHLY APPROVE OF MAKING YOUR OWN LIVE ROCK BECAUSE:

A. Easy on the wallet

B. Does not deminish from the Live Rock supply in the ocean (where it rightfully belongs)

C. You have the ability to make the Live Rock in the shape you desire
--------------------------------------------------------------------------
OK, now that we have all the stuff, lets get started.

1. (x2) Drill a hole in the bottom of the plastic container (make sure its the size of the connector you are planning to use, i used a 3/8 inch drill bit)

2. (x2) screw in the water hose connector to the hole accordingly, and test fitting by adding water into the container and check for leaks ( seal if neccesary)

-Note: This makes draining easy by just keeping the container where it is while curing, all you have to do is screw in the water hose, and place the outflow end where you want it to drain (into street for me) and turn the valve to let the flow out, the water pressure and gravity should allow for most of the water to leave.

3. Get a rough idea of how you want your DIY LR to look
Tips: Think 3-D when designing your rocks, and build from the bottom up.
Keep in mind the following concepts when brainstorming LR:
-Utilitarian, sturdy base
-Largest Surface area possible (more surface area, more biological filtration)
- caves + relaxing/hiding areas for your livestock
- you want to keep your livestock entertained (seriously) by have many swimming paths, holes, caves tunnels, etc.



4. Fill a seperate container(s) with the play sand only a few inches deep (you should choose your container accordingly to your tank size, and how large you want your piece(s) (ie: for a tank 24 inches high, you dont want to make a piece of DIY LR thats 36 inches high)

5. Once you have your sand in place wet it with a mist of the water hose (you want it to be like the sand at the edge of the water at the beach) and begin designing your live rock in a 3-D pattern by removing the sand out with your hands/tools. where you remove is where you will be filling in.
begin with the base area of the rock.

6. Once you have your base area designed, begin making your agrocrete mixture by adding 4 parts crushed oyster shells to every 1 part Portland White Concrete I/II Mix, i also like to mix in a little bit of play sand (only maybe a handful) to get a grain-like effect (from what i have read, silica play sand will have no short term or long term effects on your reef) Mix the dry components well

7. Once you have the dry components evenly mixed begin adding water will mixing evenly amongst the dry mix ( should be 1 part water that is equal in volume to the cement)

8. mix until you get an outmeal like texture of the DIY LR mix, you can add any of the components to get the texture you prefer, i like to add more shells to give more surface area and more porous rocks.

9. At this point, i like to spread the pasta mix of assorted pastas over the areas of where the LR mix will come in surface contact with. I also like to place small pieces of cheese cloth and/or bubble wrap the same way as thep pasta in order to get different types of surface areas (cheese cloth gives a scored effect, while bubble wrap creates a honey comb effect)

10. Begin scooping out the LR mix of the container and placing it accordingly into the spots you have created (with or without the "texture creators")

11. Begin moving up the sculpture by adding more wet sand ( i like to keep this on hand in a seperate container ( some people use dry sand) and filling in the hollow areas ( add "texture creators" as you choose)

Tip: Think unique creations, yet balance, you dont want to ruin something just because it wont stand up-right

12. Once you are satisfied with your sculpture, set aside to dry and repeat as much as you want, (you got 385 lbs to play with)

13. The Drying process depends upon the mixture you made, it will normally take 24-48 hours, so keep a constant eye on the rock, but be extremely careful when removing from the same. (Patience is a virtue).

14. Once fully dry, hose the rock off and physically remove any left over sand, pasta, bubble wrap, cheese cloth, etc.

15. Set aside to dry again

16. Place safely inside of your new curing bin.


Something i discovered along my trials and tribulations:

I realized that there is something to be had with frags, so i had a brainstorm. Here it is, goto the local grocery store and pick up a pack of the plastic mouth wash dixie cups. Catching on yet???

fill about 10 cups with your mix, and if you place the cups randomly inside your LR while creating it, you have a self made, fitting to glue your corals to, and when you remove the cups your fittings will fit snuggly into the crater created by the cups (pics coming soon). Giving you a way to move corals when neccesary without and harmful/damaging mods to your rock. if any needs more info to understand this (dont know if i explained it well) just reply to this thread. you could also use these plugs for a propagation system for corals.

More to come when the curing begins. Leave any experiences, comments or suggestions, hopefully this will become a sticky,

Sincerely,

DLChaney

Same = Container (wtf was i thinking about?)

filling in the hollow areas with the crete mix


anyone find any more, correct them for me lol, ty
 
I made some DIY rock recently also using Garf's recipe. I currently have it curing in my bathtup (no my wife is not happy about this). It's been about 8 weeks now. When is the PH gonna stabilize????? It's killing me!!!! I change the water twice a day and the PH is still off the scale. I'm very curious to see how your project unfolds. I particularly like the pasta idea.
 
i cannot credit myself with the pasta idea, i got this idea from reading a post of Coyote, so i give him full credit, and the curing just depends on how many water changes you do, and other factors, such as did you wash the oyster/coral shells before using them in the mix?
 
I like alot of your ideas,
1.But the pasta thing. I don't know about if some sticks to the rock or the pasta breaks off then you have a food source inside the rock leaching out sugar all the time.
2. Bubble wrap very nice bet it makes things bubblely.

3. Good Idea about the oster shells from a farm suppy, Do you wash it before you mix it in? (I am going to pick up some of that soon.)

When I make it I usually go to the local acrylic supplier and ask if I have their shavings from the table saw.

I add this to my crete, It is all different colors so it adds alittle spice to the extra white rock before it gets some good growth.
Plus since it has a different coeffient of expansion it creates a space all the way around the plastic, and when the crete drys it separates from the plastic.
Sometimes If I have a thick area I ball up alittle and stick it in the center to make the piece lighter.

Just some thoughts.

Keep us posted!
 
Nope I didn't wash the oyster shell first. I just mixed it all up together. Maybe that's why it's taking so long. I would probably have given up by now except that there are some killer pieces that I reall want to see in my tank.
 
i would try using muriatic acid (sp?) or vinegar, i have heard this work wonders, i would also try increasing the amount of water changes you do. Also, you can goto wal-mart and buy a few bubble stones and put them at the bottom of the curing container, i heard the constant flow of aeration and bubbles increases the curing process by alot. Just a few thoughts though, and yes, you should wash the shells as best as possible because all that dust is basically dry up oyster, not oyster shell
 
I've also used vinegar and it drops the ph REAL low for a day or two then it comes back up. I'm doing two water changes a day. I will try the airstone though and see what happens.
 
Moeandicy:
Just out of curiosity do you have well or city water?

I am betting that it has either a chemical or natural hardness to it (some kind of dissolved basic material) in that as you do your water changes you are actually adding back a Ph spike.

Test the water from the tap and let us know.

P.S. If you are using water from your tap in the tub most likely the connection to your shower unit has copper pipes leading to it, and if it was putin before the early 80's pipes were sweated (connected) with a lead (Pb) flux core.
 
Already tested the tap water and it's very low. When added to the rock it raises after a couple hours. The house was built two years ago. It's definately the rock still curing.
 
About the pasta leeching sugar into the water comment. . . after several months and many water changes, the pasta will be dissolved and 100% gone before it makes it to your tank.
 
I've heard of someone putting small pieces of DIY LR in their toilet tank to cure... a water change with every flush.
 
Images of my progress so far

This first cave is with Rits Dye (Purple)

I plan to make a batch of green and a batch of purple and do some mixing and matching

Tell me what you think

This second batch i didnt use Rits Dye, and here is some rubble pieces

Rubble.jpg


Here is an upclose look of the textures of the rock, i tried using bubble wrap on some pieces (top right corner piece) in order to create more surface area

Rubble2.jpg


Here is the container i was talking about and the view of the nozzle i plan to use to drain the water quickly

Container.jpg


Here is an arch of non rit

Here is a mini cave i made

Bubblewrapcave2.jpg



Here is another view of the cave (notice the texture)

Here is a double arch (dont think i will use this)

Doublearch.jpg



Here is me waiting for stuff to dry, giving the crazy eye

readytogo.jpg


Here is a tube i made

Tube.jpg


This is a large piece with the "plug" i was talking about, notice the circular hole

LargePiece1.jpg


And this is the "plug" that corresponds with the hole

Plug.jpg


Here is the plug in place, nice and snug

Largepiece2.jpg


Here is my helper (My GF) all tuckered out.

Here is a picture of all the LR and plugs i have made so far, some pieces are total crap, and i will be selling them by weight after curing them if anyone is interested, if you live in the Houston area, i will even take the time to drop it off at your location.

So far, not so good, only have a few pieces i am satisfied with, and i still have lots of ideas brewing in my head, i will keep posting pictures of the rocks and more of the actual process itself, leave some feedback, positive or negative, either is good
