I'm in the process of building mine. Hoping to be done building by the end of the weekend. Here's a teaser:

Build thread here.

Update:

any thoughts on that epoxy i posted earlier????????

 

[CoRPS]

What epoxy to we get to apply the sand? Is it spray on or brush on?

 

[maddmaxx]

as far a using rock salt to add texture to the foam. what type of salt should be used.....i like the way it looked after the salt was dissolved away....

 

[marinelife]

I would have over 1000 pounds of rock covering the foam on the bottom so it would not go any place.

I have a little foam tip for you guys. turned out pretty nicely for me on a test piece of egg crate.

About 10 minutes after you spray the foam on use a piece of wood to rough up the still soft surface. Cut up a straw and stick it in various spots in the foam. When it's hardened pull the straws out.. This is what I got without cutting into it at all...

Edit: Here's a better picture

 

[marinelife]

Would you guys say this foam seals the area it covers?

if i where to use a resen i would use epoxy resen. there have ben a few on rc that have used fiberglass (polyester) resen that you can get at an auto parts store.

the YES was for this question "where can i get the crystal rock salt? home depot, lowes....."

 

[CoRPS]

Is the epoxy resin spray-on?

Foam wall in my 37 gal cube, looked amazing to me until it floated up after about 3 months

didnt you use any silicone on the bottom to keep it down?

Yousmellsfishy, when you did yours, I see you zip-tied the rock to the eggcrate, then did the waterfall foam thing, then added your home-made sand. Did you add the sand right after you added the foam?

 

[maddmaxx]

thank you cause after reading his post i looked back and didnt know. initially i thought the answer was for me. again after rereading it, that could have gone either way...joeypantagco eyed that.. good catch
