I absolutely suck at aquascaping

Easily cut-able down the road if you can remember where you tied it


remember when you set the rocks inside the tank, Rocks first, then sand. that will be the main reason your rockwork shifts if it ever does.

i do have fiberglass rods ready to go, so i will drill and use those for sure with some rocks. Others i will super glue and cement together. Bigger issue is that between some of these, there are like 2-3 small points where rocks touch, so nowhere enough room to drill a rod and place, unless I want rod to be visible. Was thinking about zip ties, but heard the will fail and snap over time, especially with salt water. Will play around with it more and see if I can build up few of these to have more contact. Then I can cement them in place.

I like to drill the rock and support it with acrylic rod, this makes it super strong. Then I use reef safe epoxy between the rocks to prevent them from pulling apart, you can even push small pieces of rubble rock into the epoxy to help hide it when you are done, after a couple months you won't even see the seam

What brand is reef safe epoxy?

[adam84]

Just the plain old two part sticks from any lfs instant ocean or the fluval one

Oh... that old stuff. I thought you meant real epoxy lol.

Instead of those two, you can use JB water weld or Loctite epoxy. It is same stuff but cheaper than ones made for "aquarium"

I found that if you glue too big of a structure together, it may cause issues if you need to get livestock out etc by HAVING to remove the rock.

This is why my preference is to epoxy , but also pin pieces together so it can be dismantled easier if needed.

yeah this is one of my worries, not just because i wouldnt be able to get rocks out, but I wont be able to get rocks in once I am done with scape as well. I have acrylic tank that has full brace on the top, and just 2 bigger openings. So I have to make sure that whatever I make can actually fit inside the tank through one of those 2 holes lol
