Dan's Jelly "Pseudokreisel"

[sphelps]

I'd use an oven for the bending, a heat gun on that size of sheet will likely give less than steller results.

170°C should work well for cast material but don't use a gas oven. For best results build a wood mold with the right curvature and place the sheet on top of it in the pre-heated oven. The sheet will form around it by itself.

You know I am in!

Do you know how much he wants for that chiller? You may have solved my problem.

Do your homework on this. I think you may need permits from DFO for collection of jellies. I know of someone else that did this and they were required.

You must seriously love her. Lol

Jealous. I've been wanting to do this for years.

Go with thick acrylic for the front viewing plane to avoid condensation problems.

With the overflow, make the top of the screen below the top edge of the tank. That way when (and not if) that screen ever gets plugged, the water can over flow past the screen and into the back, rather than onto the floor.

Where is the inlet coming from back into the tank?

Check out this guy's plantonkreisel design: http://www.biolbull.org/content/204/1/68.full.very nice in that the inlet creates a laminar flow over the outlet screen which prevents jellies from getting stuck on the screen.

Yeah, she is alright

It helps when you get to do a sweet aquarium for a birthday gift and not something lame.

Thanks for the link! I'm hoping 1/2" is enough for the condensation, but maybe for that panel I should go thicker?

Cool, I tried on a small piece of scrap acrylic and was pretty impressed with how easy it was to bend.

I have a piece of large 24" PVC that I was going to use to bend the acrylic around as a mold. I don't know if I could fit it in an oven, but I do think that method is definitely better than the heat gun.
