From above
This structure is a piece of the aquascape for a 300gal tank.
This one is 25" long by 15" front to back. I could easily make it larger.
Some things I learned......
* You can use any accelerator. The one that BRS sells and uses in the video. It is very difficult to spray.
That being said you can use these two.
* I have tried numerous different glues and like this one the best.
Another member suggests Glue Master thick. I havent used this one myself.
* The foundation rock is very useful (albeit expensive)
* Take your time and stand back while deciding on the placement of a new piece.
* If you use Marco rock be sure to purchase the matching mortar. It blends with the rocks well
You will make the final dressing up process very easy.

* Let the glue dry overnight before applying mortar.
* LIGHTLY wet the rock before applying mortar. If it is too wet the mortar doesnt stick as well.
* Once the structure is super glued together you will find it difficult to see every place that you have glued
especially on the underside.
* About an hour after you apply the mortar spray the whole piece down with RODI water. This helps the
mortar cure. If you do it too soon the mortar will run down the structure.
* Use a flashlight to inspect your mortar joints after they dry. I totally missed some on the first two passes.
the third time was a charm.
* Make sure you counter balance the weight of the extensions by adding weight to the opposite side.
* Have an idea of how you will be positioning corals on the structure and add a location to house it.
* Definitely use gloves with the mortar. The gloves make it easier to apply.
That's all I can think of at the moment. Keep in mind if you build part of the structure and dont end up liking it you can always hit it with a hammer. I did twice while it was only glued.
Take your time and de-stress I found it to be totally enjoyable process except for the removal of the glue from my fingers. Also take off any rings or you will end up super gluing it you your hand
All the best and if I can provide you with any additional info dont hesitate to reach out.
Be well and happy reefing
