I have come back to this site over and over getting new ideas. I actually just aquired a 40 gal hex and plan to start a new vivarium with it.  Believe me, I will be back several times to use your valuable pointers.  Thank you!

David, I was wondering what you did about the the little pond at the bottom. Is it free sitting or do you have some sort of filtering system going on.  I have the same aqauriem I'm working on but I haven't gotten all the plumbing figured out. Any suggestions?   Thanks, Daren

Could you, if you have time email me some more details on the ventelation system, and overflow systems? Thanks.

Thanks for this fantastic site.  I have been searching all day long, then I came upon the European site that referred readers to this site.  I was wondering about the concrete bonder, peat mix, which having done much work with hypertufa, I might add a bit of sand to mine, for my purposes, but your photos show how great the end product looks.  Once I tackle that, I will start to tackle the mist functions, which is overwhelming to me at this time.  Thanks again for taking the time to illustrate your project.  PS. After reading much at different sites, and growing moss myself - an aside, I had tried various found mosses, and the one which grew and has been thriving on a small piece of wood in a terrarium now for about 5 years is moss I found in a crack on the side walks of NYC! - at any rate, on various boards (Garden Website perhaps) it was mentioned that for wet environments the Java moss most often used under water in aquariums did especially well in wet - mistly, or 'rainy' environments - spreading out from the water, or waterfall feature, to other areas not underwater.  That's something I plan to try when all is done.  Thanks again Sherry

Hey, I'm setting up a 20gal upright using your background method. I was wondering if you new the brand name of the concreate primer? Does Loews or the home depot carry it? and how has it held up against moisture/water... thanks. Cant find your email.

Very nice system! I also have a rainmaker Jr misting system.  I wondering what RV pump you use now?
Thanks

great photos, but i have a few questions. how long does this product take to dry? how safe is it, did you do a pH test and what about leeching? any toxins present while it's drying? why are you using expandable foam instead of wire mesh cloth? also, how long did it need to set, both the foam and the cement stuff?

I was hoping you could tell me more about your substitute for "flevopol"  Once the substitute is completely dried can you run water over it for say a water fall?

Bob; sounds like you're using too much primer.  There should only be enough to make the peat stick together when you squeeze it, then break appart when you poke it.  I applied mine immediatly after I mixed it and it was completly dry in less than a week.  Make sure you have good air circulation and some heat wouldnt hurt either.  Good luck!

David,really liked the 40gal.hex.have tried the mix you spoke of,but only the surface seems to harden,did u let the mixture soak for some period of time  before applyingif so,how long,am really trying to get this work for me,it looks great,thanks.

great work david ... i'd be very proud of it.  looks very professional!

Great looking Vivarium, good job. I have visited the dutch sites and have wanted to build one, and you have done exactly what I envisioned. Please contact me I would like to discuss the project further.
