Lets see your Ultimate DIY Rocks!!!

It was US$0.25 per pound back then. I would imagine it would be about the same today. They sell it at concrete and decorative (garden) rock stores up here. That piece is about a pound, so you could do a nano tank for a dollar.

I think you can buy it in flat slabs if you wanted to do a back or end wall. You would have nuisance algae problems, but no more than any other non-calcareous rock.

I just can't believe how many times I've moved that $0.25 over 15 years without chucking it. It explains why I haven't had fly-bot problems all these years.
 
here is a few pics of just 1 rock. lots of spots for stuff to hide!<BR>

Mr Wilson, I love that first tank you posted. I am curently trying to figure out ways to get a similar effect of the delicate rock arches.

Customcolor, I dig the huge arch you made.

Y'all are just too enthralled with the chemical side of this rockmaking now. I gave up on speeding up the cure time and am just enjoying the trip.

Now what I am really interested in is if anyone has had any luck making tall, delicate towers or arches? Thats my next path of impossibility.
 
i have a confession to make, only the uprights are diy live rock. across the top is pond foam that was coated with crystal salt befor it expanded then wased off after it did. it is hard to tell i think unless u look realy close. the peices on the sides are rock too covering up some pvc returns
 
Here are two I just made. These are my first two. The left one was cast in salt, the right in sand. This is after 24 hours. I took them out of the molds after 12 hours.

They were made with Rapid-Set brand cement (they say you can drive on it 1 hour after it sets). This stuff looked more white when I bought it, but is really more gray. It had rocks in it, which I didn't realize, but I sifted them out really easily. I posted my recipe in teh Ultimate DIY rock thread, but IIRC, it was around 1 cement, 0.5 sand, 2 perlite, 0.5 crushed oyster shell.

Well, I got a few new shots of a tank I put together recently.
Its a 168 gal Cube. Its been set up for about a month now,
so its starting to show a little bit of diatom algae on the rockwork.
Had to make a plywood mock-up of the tank to build the rockwork.
Each piece can be removed if necessary. Even the rock covers for the closed loop system.

This tank is installed in the wall between the Living Room and dining room at my friend Carlos's house.

This can help identify the overflow and closed loop.

Actually, its an arch. Kinda hard to tell in the picture, but The overflow has an arch that goes out 3/4 across the tank and then terminates in a pillar. Offset from that by at least 8 inches is the other wall of rock. The lone piece really only covers a corner of the tank. The numerous branches that protrude from the arch and the lone wall of rock do give the appearance of a connected piece in the tank.

This tank is 3 foot on each side roughly!
