This stuff is plastic but a little flexible - it would be impossible to snap a sheet by bending it unless you were VERY strong!

It really doesn't take all that much to break light diffusers...they pretty much snap..

This stuff is very strong in comparison then - in fact, in a few places i hacked large sections of it away so i could get access to the rear of the structure so i could get rid of extra foam - and there is still no way 20kg of rock leaning on it will bust it...at worst, if all the foam fell apart it would just bend a bit.

I wonder if instead of foam if using something like thorite (hydraulic cement) would work. wouldn't have the float factor and it wouldn't have to be epoxy covered. plus it would be easier to push the sand/crushed coral into it because it wouldn't be pushed out.

problem with cement is:

it would make the stuff sink...but be VERY heavy! I can easily lift my entire aquscape into the tank myslef.

it cant be trimmed - where the foam runs but is not needed i can just hack it away.

doesnt it need time to cure?

i've read that stuff doesn't affect pH as long as regular concrete does. dunno. I just bought my first container of it to try it on some rocks. even if it does need cure time, I can live with that.

You could always use an epoxy with lots and lots of filler. You could make it very chunky if you wanted. Foam is the best way to fill the area up though.

just some thoughts......could you not use salt? as well as sand. Once disolved it would give the foam areas more texture. just a thought taken from the diy rock thread

no need for salt - smothering it with coral gravel is easier, quicker and looks better.

Has anyone tried adding plastic mesh into the mix to help with the porosity?

Enkamat may work really well for this I imagine.

What do you guys think?

dont forget this structure is 75% real rock - the foam is just there to hide the joins between different bits of rock of the cable ties etc.

considering the better layout of rock that is achieved i would say the real rock (once live again) will be VERY efficient compared to a traditionally stack of rock as used normally.

Tiggsy what type of foam is that you are using? Is it the standard stuff you get at HD or Lowes or is it a special "reef safe" product?

you could have used salt if you use diy rock and black pond foam like i used in my build. like this. the foam is across the top that had salt on it to match the diy.

rocks all done now, just needs a little touch up once in the tank.

75kg of rock used.....leaving a lot of swimming space in 180g.

last pic adds the tank dimensions for scale, they are 48x30x30 - a 28" water height with the rock peaking at 29".
