lpguy Posted August 13, 2005 Posted August 13, 2005 Ok heres the idea: I have base rock that i want to drill holes into and then use a dowel rod to hold them together. Are dowel rods reef-safe? What would be a good alternative if they are not?
lgreen Posted August 13, 2005 Posted August 13, 2005 no. the wood could be chemically treated. not worth the risk. some people use large black zip ties from like homedepot or get some of that frag putty to glue them together.
dhoffroad Posted August 13, 2005 Posted August 13, 2005 yea I would'nt trust the wood...tap plastics has some plastic rods that you could use if you were set on doing it that way...but yea most people use the putty...
lpguy Posted August 13, 2005 Author Posted August 13, 2005 Is that putty strong?? I will have like 50lbs of rock i want to put together and make it strong like 1 piece.
thebrian Posted August 14, 2005 Posted August 14, 2005 Cut-up plastic clothes hangers (the cheap rounded ones) work well. The plastic is reef safe also. ~Brian
offsprg01 Posted August 14, 2005 Posted August 14, 2005 used super glue gel and acrylic rods from tap plastics. that will e your best bet. if you aren't building some kinda crasy shelf type thing you should even have to use the plastic rods. the suber glue gell will hold super strong once is sets. i used it to secure both of my large arches in my tank. hth
Reef_Mad_Man Posted August 14, 2005 Posted August 14, 2005 Acrylic dowels are the BEST for this job. Ridgid airline tubing, plastic dowels, PVC tubing, zip ties and reef epoxy, just plain reef epoxy, those are all ways people have held thier rock work together.
Sarduci Posted August 15, 2005 Posted August 15, 2005 I've got 18" tall, 20" wide 10" deep rock stacks from using Aquamend (drinking water safe) build from dry rock. It cures for 24hrs and then it's harder than the rock itself. If I don't like something, it's hammer and chissel time after about 12 hours.
