PVC rockwork frame question

Hi everyone, I was wondering about the use of pvc for
aquascaping a reef. I would like to make pillars and
a mountains with numerous caves and decent surface area
for the placement of corals. Its will be in a 75 gallon
(18"x48"x20" high). Im wondering if a way of doing it
would be to use thinner pvc and drill holes in the rock
and enclose the pvc (kinda like putting donuts on a stick).
I could use the coral epoxy to stick rock rubble and sand
around visable pvc once the structure is complete. I was
thinking of putting "little feet" at the 4 or 5 contact
points to keep the rock off the sand also. Im thinking
since i would be doing alot of fitting out of the tank
that my rock would dry out to some degree but i guess it
would be worth it after all was done...ne one done this
or think its a good idea?
Thanks
Dennis

 

it can be done, but i would get some starboard or something so there isnt areas with more pressure on glass than other areas.

 

Hey aqua boy, what is starboard? place it under the sand?

 

Dont glue te stand as it will start to get heavy, you could just join it togetter

 

Wastemanagement, i dont understand your last post. Are u saying dont glue the rockwork to the aquarium?

 

LOL no I mean the pvc

 

Oh, no i wouldnt glue the pvc to the tank. I wanna make to sections using the pvc as a skeleton for each side of the tank leaving the center clear for fish swimming room. Would u happen to know what aqua boy was talking about when he mentioned starboard?
