Hi Motor, thank you for replying! I agree on a bit more sub, for settling. What do you think about "fluffing" the first 1-3" or so, if all carbs are up? Just in case I have any high flyers who might fall, or if there any other benefits or warnings?Motörcrab wrote: ↑Fri Mar 05, 2021 6:46 amA lot of your questions are a personal preference. Some things like depth of substrate can depend on species and crab size.
1. As curly stated 6" is a good start. I like to start with a bit more sub, maybe 7-8" since it tends to settle over the first few months.
2. Mixing sub I like to mix a bunch of smaller batches in 5 gallon buckets. I feel I can control the consistency a lot easier. It's more work, but it's easier to add more sand if you added too much water. Once mixed I like my sub to where it feels dry, but if I poke a finger into it, it keeps a hole.
3A. A lot of people made stands out of plywood and 2x4's. Making a stand would probably be your cheapest option, especially since you want something lower. I would put two 2x4 together for each corner, then add a three 2x4's in between. Due to the weight I would rather over engineer the design so it doesn't collapse.
I would avoid any tables that do not have a load rating that's at least double what you are putting on it. I work in the amusement industry so everything is always has a high safety factor.
3B. I usually sketch out my ideas on a paper. I don't have anything to exact scale but close enough for planning.
4. We have used foam insulation board in the past. It works but makes a mess cutting. We have found Reflectiix works very well and is much easier to work with. It's similar to bubble wrap but for home insulation.
We run tow UTH's on our tanks. On our 75 we have one across the back 11x 47 hooked up to a thermostat. A second on the side we plug in as needed.
Our kitty Fleabag helped with a heating guide a few years ago! http://www.hermitcrabassociation.com/ph ... e#p1072369
If after I have my sub in place, mixing parts at a time is it a good idea to do the chopstick/dowel rod/etc. test and wait maybe a week, just to see?
I like your design idea, if my coffee table inquiries don't pan out could I contact you about making a stand?
I'd be using Reflectix tape but also wanted something a bit more like the foam insulation. I don't mind about the mess. Also, does the tape "slide"...? With the inside temp being 80+ optimal would the glue lead to sliding, so the UTH's would "drop"..?
Also, what is the best way to mount UTH's using a tape method...? Before sub, after?
Thank you so much!
