NSA build question

[Marc G-L]

How Much E Marco 400 per joint should I use after heavy use of CA and Marco rock powder for my initial structures?

 

[Hooz]

I used thin super glue, Marco powder and NO mortar. The oldest scape I did like that is still holding up great 5+ years later.

I used about a nickle sized spot wherever rock touched. Afterwards I used sand and superglue to hide any connection points.

Thanks everyone. I also did the CA and Marco rock powder method. I decided that after having a few supposed strong junctions separate under stress, (even though multiple contact points and layers of the above method,) I followed up with EMarco-400 motar on their underside.

Several days later deciding to enhance my NSA to an HSNA, required chiseling out the rock now held by the cured motor. I feel confident that 5 yrs into my tank's life no junctions will separate. Some studies show CA in the presence of salt water and UV/ Bluelight spectrum can break down.

A few hrs more work but,I bought a cheap insurance policy doing that.
