hello out there.

I am setting up a 75gal tank and i was trying to do some aqua scoping. I purchase two (16"width 10" 1/2 length 1/2 thick ) acrylic sheets and i was going to drill holes in the live rock and acrylic sheets and then place rods in the acrylic sheets to slide the rocks in place. my question is, can i use metal rods to place in acrylic? i went looking for plastic rods but was unable to find some anywhere the type that is threaded because i can screw nuts in place to hold rods up. have anyone tried this before if so i am looking direction thanks in advance.

happy reefing!!!!!

Don't use metal.
Do a google search for acrylic rod, plastic rod.

is there a reason why not to use metal?

acrylic rod is easy to get, easy to work with, glues to the acrylic sheet you are using for the base, why not?

i was thinking the same thing. but i didn't thinking it was strong enough to hold the live rock and i wasn't to sure on how thick i should go with the rods.

When I set up my 240, I bought some scrape acrylic from a local tank maker. I was lucky to find some 1" thick stuff in his junk pile.
I bought some 1/2" acrylic rod and drilled holes in the acrylic to put the rod into. Anywhere from 2" to 6" long rods.
I didn't drill into the rock, I just stacked the rock on top.

how did you get the rods to stay in the holes you drilled? did you glue it ? why didnt you drill into the rocks?

Weld-on is designed to bond acrylic together. Couldn't you also
thread the rod and tap the sheet(?).
Also will you have rock around the base for support?

I used a 1/2" drill bit, the same size as the acrylic rod. It was a snug fit. You can get some weld-on glue when you find the rod.
For my application, I just didn't think I needed to.
The rock stacked up very well and has been very stable the last two years the tank has been setup.

Why go to that much hassle?
Just drill the hole in the acrylic, use the same size drill bit as the acrylic rod and it's done.

Don't make it more complicated than it needs to be.

i went looking for plastic rods but was unable to find some anywhere the
type that is threaded because i can screw nuts in place to hold rods up.


Cause he asked about threaded acrylic rods.
