What kind of PVC to use for rock stability

[clownchic]

I've read people drilling through their rock to make their formations more stable. I am definitely interested in this. I've had two rock slides in my small 25 gallon and I DID NOT ENJOY IT! I'm getting ready to set rock into my 90 gallon and would like to use PVC tubes threading through. Any suggestions? Do I need to buy the PVC that is for potable water?

I have seen people make pvc platforms and all of that, but drilling thru the rock and inserting pvc thru the rock is a new one on me. Many people use pvc to make stands, plat forms powerhead risers ect. Its the regular plumbing pvc found at your local hardware stores.

If you decide to drill your rock I think you will find PLASTIC coat hangers will work easier than pvc pipe. Cutting a couple hangers up will net you several cheap plastic rods than can then be inserted into your holes.

For a tank the size you are dealing with I think I'd just get a couple tubes of Aquamend from Home Depot and use that to build my reef structure.

I purchased two tubes of aquastik to secure smaller pieces. The hanger idea is good and that would mean smaller holes in the rock. I decided on this method because I want a very open structure that is also very stable.

sounds great something i would like to do as well .... but if i can ask another question. What type of drill bit is good for something like this ?

I'm going to just try a regular wood bit. I have Marshall Island rock. If that doesn't seem to work I guess I'll try a concrete bit. I'm hoping it will the pipe will just thread through the hole and act like a piece of reebar does in wood.

Concrete bit works ALOT better.Wood bits might make it but usually don'tand if they do it's only by shear force. I'd recommend the coat hanger method or acrylic rods if you have a plastics supplier close they are alot smaller than pvc pipe, just as strong, and the clear acrylic isn't visable.
