I used hydraulic cement on my last build and that was a horrible idea. Mixed thoroughly, dry cured for a week and a half, soaked in RODI for another week with multiple water changes and then put in the tank. It lasted a year and a half an now I'm dealing with the cement disintegrating and the rock scape falling apart. To say I'm upset is an understatement after the amount of research and time I put into making the scape for it all to fall apart.

Trying out E-Marco for the first time...as I attempt to follow the NSA approach for a 40 gallon breeder build. Tip: You when using super glue and instaset to first build the structure - you can find a 8 oz ‘refill’ size of insta-set on Amazon.com and save some $$ vs buying more of those 2 oz spray bottles!

I used marco cement and aquastick putty when I did my initial install. The cement is solid, sometimes the putty doesn't stay put.

I also use balance on a few pieces, much of the left rock work was cemented, but the leg is balancing it. The right side was eggcrate attached to my return manifold and filled in with cement and small rocks. I even made an overflow cover but since removed that. The marco cement has held up for over ten years. It cured quickly and I used wet live rock in the build.

Setting up a 136 gal tank and put this together with just superglue so far, will be filling in the gaps with the Marco mortar mix later in the week

I used this method on a 90 gallon I had once. I wanted to cover the unsightly overflow. I used super glue to adhere rubble to it. Then found out Pond and stone great stuff has amazing adhesion holding the pieces in place. Then I sprinkled sand on the great stuff while it was still sticky. Afterwards I covered it all with tan Pond Shield. I will say it came out amazing. I also used this method for bonding the rock together. The pond and stone great stuff is great for bonding even heavy pieces. Most of all all of these products are non toxic and had no issues with my reefs. This method is also good for making a 3D background.

+1 on the Instant Ocean epoxy. Great stuff!
Currently using Marco cement along with epoxy and thick CA/Kicker.

Thick CA/Kicker works great for gluing fiberglass rods on one end for initial positioning and holding power during cure.
IO Epoxy works great where the joint needs extra strength, such as a narrow joint at the top of an arch or a small contact area for a bigger piece.
Marco cement works great for filling larger spaces, and it's okay for adhesion between large areas.

I had great success (so far) CA gluing a dowel into one piece and fitting the next. Then mixing Marco and piling it around the dowel, adding a generous portion of CA to the exposed dowel end and squishing the whole thing in place. The CA sets quickly and holds the two pieces in place while I work the Marco into shape. A final dusting of coral dust and pieces impregnates the Marco for a better color match and improved texture matching.

Has anyone used those plastic beads that you're supposed to boil in water before use? I know a couple companies make it. I tried a little because i was curious but couldn't get the stuff to stick if my life depended on it. It seemed to cool off too quick and was a PITA.

I used super glue ultra thin and sand. Creates a quick bond but beware of the fumes.

Yes I’ve used it, I believe the one made by Aquamaxx, it will work but you have to use a lot more of it than you would think necessary. I agree it is a PITA. I used acrylic rod and E Marco on my last scape, here’s a pic when it was bare rock

We sure love to imagine beautiful reef tank aquascapes in our home reef tanks but seeing them and accomplishing the vision are two different things. Besides live rock one of the key ingredients for a spectacular aquascape is the epoxy or cement that holds it all together! Today let's talk about it!

1. What's your go to epoxy or cement when it comes to keeping an aquascape in place and why do you prefer it?

2. What other methods do you use, besides an "adhesive" to keep your live rock in place?


BONUS:
Show us a photo of your aquascape!

all i can say is WOW and AMAZING.ive only used epoxy once on my wife tank and in my opinion the green epoxy sucked ,it all let loose, but the gray worked wonders. held like armor but the color doesn't match. we have added a ton of bottled coraline algaebut its going to b a long time before that starts to work. all my tanks are free standing so if I want a change I can but think ill try some other things for future. you guys really took it
