In an attempt to force myself to finish the vivarium im working on im going to loosely document it here in one thread, that way when it is done not only will it maybe be able to give others hints and tips, regrets whathaveyou, but ill also appreciate the feedback from everyone. So i started with a 29 gallon critter keeper, the one with the full screen sliding lid on it, were i to do this again i would just use a regular glass aqaurium instead, but i got a good deal on this one. I will be flipping the tank on its side, so it will measure 2'5" high. I took the sliding lid off, and instead of buying window framing from the hardware store i cut the screen that came with it, creating a screen door that could slide independent of the glass door for more access to the vivarium, this way, in theory i'll be able to take out both the glass sliding door, and the screen sliding door, and have almost complete access from one side of the tank. Unless of course i get tired of trying to figure the sliding part out and just silicone it in. Im using the greatstuff and expanded coconut fiber method for the backround of the tank. I bought greatstuff foam: window and door, and bronze(brown) GE Silicone II. I opted to instead of buying the predryed coconut to use a brick i had around the house, simply drying it in an oven at 350 degrees, though if i did this again i may just buy the predryed coconut substrate, more expensive, but i dry the coco fiber in pans, and i think i spend more time doing that than working on the wall. after smearing the back of the tank with silicone, i let it dry and cure. After fully cured I sprayed the greatstuff foam, letting it cure fully before starting to add the cocu husk to the backround. So right now im about 65-70% finished there, and think i may have gone a bit overboard with the texture of the wall, i used two cans to cover the back of a 29, even though ive read two cans can finish a 55+, there are some very hard crevices im having problems getting the fiber into, i do like the effect of it being so textured, but were i to do this again i think i would look around for Handi Foam, just like greatstuff but black, it would just hide mistakes so much better. As of now this is the point im at, next will be locating a good glass cutter nearby for the glass for the door and trap on the bottom, or finding somewhere that sells plexiglass thick enough for groove it has to sit in. Then on to creataing the drainage for the bottom, im thinking LECA balls with window screening and a 50/50 mix of expanded coco husk, and organic potting soil for that. I did want a waterfall, one that would start near the top and cascade down, but decided against it, because everything would have to be concealed in the foam backround, and if anything were to go wrong id have to rip out part of the backround, maybe if i build another vertical viv ill find a better way of featuring one, but for now i've decided against it. I could always build the styfopor (i think thats the word) small tiered waterfall, but i think ill just be adding a dripping feature to the tank instead, i was thinking about getting tubing and having a container above with water so i could have quite a few spots dripping water off of one basin above the tank, probaly better than having like 4 drippers set up. So, any feedback, comments, all appreciated.
