Default Pin and Epoxy

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

If you have some pieces that you know for sure you'll be using on the bottom, wet down some sand paper, put it on a flat surface and shave your rock bottom to a flatness that works for you. It'll help with the stability and also give that look of and endless sand depth as rock seems to rise up from the sand bed.

I used 150 Grit that I had lying around.

Thats a good idea, and I have loads of sand paper. I do have tile saw that I used on few pieces with idea to do precisely what you said once I have something that I am happy with. A lot faster than sand paper haha.

Played around some more with the 1st structure. Got idea of seeing if I can build some sort of asymmetrical cove out of it. Here is what I came up with so far







There are 2" on all sides between structure and panel, so that there would be water movement, and so that acrylic cleaner can be used. Structure is almost 1/2 the tank height wise. One thing I am not sure is about water movement inside the cove. I will be using 2 gyre XF230s, so it should give me enough movement to move detritus as so on.

I also started playing with idea of doing "bonsai tree" structure on the left







Idea is to add 2 more longer "branches" so one would reach rule of 3rds point top left. Not sure how this will all work out, as i just started.

Any feedback critique, info is more than welcome.

I like it, fills out the space better and has more of a 3D feel than your first go. I'd be gluing or pinning the vertical structure for sure. If you use cement on the rocks be aware that the cement will raise the PH of your water to lethal levels for about 2 month while it is curing, then a 100% water change will be needed. I cure cement in fresh water for 2 months then drain and switch to salt water. Glue will give you faster results.

If I were you I would make sure there is minimum 6inches of space between your rock and the acrylic. You have to factor into account any coral then room nonstick your hand in there to clean the glass. All sides.

This is only true if you use cement not meant for your tank. Use reef safe cement like Fijicrete and you wont have to worry.
