Question on stacking rock into columns

[iloveswfish]

i need some ideas on stacking rock, i was thinking of using pvc but not sure it would work, thought about water weld but never had good luck with that holding.

Looking for some ideas

You can also use acrylic or fiberglass rods or zip ties.

Fiberglass electric fence rods are cheap and easy to cut(hack saw)... Just look for a long masonry bit to drill holes... Farm supply stores usually have both, about $1 for a 3' rod... Use some stick epoxy to prevent wobble by packing in holes around rod. Can also look into using some spray foam to fill in the gaps and tie together [emoji1]

will the foam hold the rocks together and what kind of foam are u talking about, the and does the foam hold the rocks. epoxy says not to be used in fish tanks....

I guess it depends on how extreme you plan to be with your columns. I have a column currently in my tank purpose built to keep a magnifica anemone from making trouble and I basically stacked rocks in such a way that they locked together andcthecobserve used the D&D epoxy putty to keep things I place. D&D takes a bit longer to set than other putties, but it also sticks much better.

Lots of epoxy sticks out there "made" by fish companies... I use jb waterweld with no ill effects... The spray foam for ponds is what most use and rock probably needs to be dry... I posted some pics in my build thread if you want to see a few pics... https://www.reef2reef.com/forums/large-aquariums-180g/187576-frankensteins-180g-stick-tank.html

They do have the "great stuff", most will argue that you need the black pond foam since it has uv protection.., I find it kind of silly since hopefully you'll have coralline algae beginning to cover within a few months and by the end of a year fully covered... I use the regular poly gorilla glue and apply with a cheap paint brush to pat down bubbles that form... Maybe over 20 minutes or so and I dust it while it's still tacky with some white sand... This is all cosmetic for short term looks... It helps blend the rock and foam together... And the coralline algae will provide all the uv protection the foam needs [emoji1]
