UTH Questions & Help

piratetoothgir · Post by **piratetoothgir** » Fri Oct 27, 2017 7:31 am

So recently, I just got my new Ultratherm UTH in the mail. I ordered the 7” x 11” size, and it fits great on my crabitat. I do have some questions though, so that would great if you can answer them.

1) My tank is acrylic, does this affect anything?
2) The tank was originally for fish, and it’s specially made. Can I attach the heater to the side, instead of the back? (this tank has a built-in sump)
3) What can I use for a homemade insulator? Does foil work with tape?

I live in Texas, and it does get very cold in the winter, and we are approaching a cold front, which will cause the room to get dreadfully cold. Later into the winter, we’ll turn on our house heat. I keep my hermit crabs upstairs in my house, but the room it’s in gets cold. I might just have to move them to my room, where it’s warmer.

My main questions were those, but here’s an explanation on my tank.

It’s a System II, with builtin sump in the rear. Because of this, it causes the inside of my tank to bow outward, which makes it smaller around the middle area of the tank. The UTH will fit on the side, but will my thick substrate affect that at all? It’s about 9” on that end, which is supposed to be the hotter end.

On the other end, I have their food dish, but I also need to add their water.

Could you please answer my questions, as I really need help with this new heater!

Hello

It is okay that your tank is acrylic. You can definitely attach the heater to the side

Just do not bend the heating elements at all.

You can use foil - shiny side facing the inside of the tank - then cardboard, styrofoam, or foam board. Use tape, packaging tape or duct tape to adhere it

Multiple layers helps!!

I never cover any of my substrate with my heaters - but that's me. Heaters should go above the substrate imo. Hope that helps.

Thanks GB!

Alright, do I layer it like this? Tank - Heater - Cardboard - Foil?

For the substrate, my tank is only 16" tall, and the heater is 17" meaning it's just about an inch taller than the tank. The substrate is about 9" in that end, but I see the temperature has risen to 81.8. Hoping no higher than 83 in this case.

Thanks for the help!

I have been use the ultratherm a few days now, maybe a week? I wrapped a piece of cardboard in foil and taped to to the back and sides of the tank. It's helped a lot, as the temp drops some days. But I notice I'll need more insulation because today my house was 68 degrees and the tank temp dropped to 75 degrees. Its only gotten up to 77 degrees and I think it's bc I need more insulation. Mine is a 10 gallon as well.

I've seen others recommend reflectix for insulating. You can get it at home Depot. Also I've seen bubble wrap and packing foam popcorn things used to create homemade insulation.

Does anyone know if using craft foam sheets (layered over top of the existing cardboard) is ok for insulation, or is it a fire hazard?

Yes, they are great! I am insulating mine right now, and the temperature drastically has dropped overnight.
So, I decided to move them to my room where it's warmer.

I'll rearrange the tank again, and put some warmth inside too.
I don't know about the foam, but you can use thick foam board.

I visited PetCo today, and dedicated that trip all to my crabs!
Bought some supplies, and necessities for their crabitat.

It stayed warm overnight!
Some crabs ventured up to the moss boxes, and moved around.

Yay! That's awesome! Love your set up. I think I'm going to go to Petco today and get some moss too

Ps. Just curious, what size is your tank?

It's really cute, and I love my crabs!
My crabs' names are: Rocky, Papaya, Stella, and Mr. P, but I also like to call him "Little E" even though he's not an Ecuadorian.

I'm narrowing down my heating problem. Lol. On another thread someone (possibly you?) Recommended ultratherm uth from beanfarm. And said for my 40gal tank a 24-46 watt will be good. The only one from beanfarm that will fit across my tank, was a 6x35, 23watt. It will leave a couple of inches bare at the top. But it's only 23 watts. There's a zoomed reptitherm, 24 watts, at petsmart. I don't know the measurements. Then there's zilla large, 8x18, which only covers half the back but it's 24 watts.
What is a crabby mother to do? I would like to avoid using a heat lamp all together.

I love the ones from http://www.reptilebasics.com or http://www.beanfarm.com

I don’t care for the zoomed heaters-
