Kriesel Construction

[Bubbashrimp]

I would like to make a kriesel but I do not know how to form the cylinder with a sheet of acrylic, 90's are pretty much all I can do. I think you use some type of oven but they are so numerous I dont know were to look. I have also thought about pounding metal tubing into the ground and filling it with charcoal, since acrylic is flammable and gives off lethal gases when heated I would like to stay away from this option and have an ability to control my work as much as possible. any help would be appreciated.

Why don't you just buy acrylic pipe/tube?

 

[Bubbashrimp]

does it come large enough?

 

[Bubbashrimp]

hello?

 

[xtrstangx]

Yes, what size diameter do you need?

 

[Bubbashrimp]

where did you go undergraduate

 

[Bubbashrimp]

24 in

Cast would be preferably, but if you have to go with extruded, you can.

24 in

Nevermind, let me try and find a website that sells 24 in acrylic. They make it, the problem is finding it.

Look in the phone book for a plastics shop and see if they can order it.. that'd be your best bet because you wouldn't have to pay a huge shipping fee (although the store would probably charge a fee, just not as much)

This may be worth a shot

I have been going through cyro.com and they have a suppliers list. I am just afraid the cost would be more than I can bear. do you have an idea about how much it would cost. p.s. thank you for all your help. it is really hard to find decient help with this question. have you had any experience with building a planktonkriesel? if you do how large can the holes be on the return.

 

[Bubbashrimp]

do you know if that will adhere to Acrylite GP?

 

[Bubbashrimp]

Again if there is anyone out there that knows how to do this with out tubing, probably but not nessecarily with an oven please help

24 in Acrylic will be very expensive, especially with cast acrylic. Try getting a quote from someone who carries it. It will be a few hundred, easily.

I've never built a planktonkriesel before and I'm not 100% sure what one is, to be honest. I'm thinking it is one of those tanks that raise plankton, which is fed to rotifiers, which is fed to brine shrimp, or whatever food, am I right?

I'd imagine you could probably do it with a square shape, but I'd do some more research on that before starting.

do u mind telling me what u're going to house in that KRSL tank?

i've made octagon shaped tanks for jellyfish before, and they worked great. u don't really need a full rounded kriesel tank.
u could use 2mm PVC sheet, heat bend it to form an almost round curve and fit it into a rectangular/square tank. but if it's for jellyfish, then u might need to seal it all round.

what a planktonKriesel is

what a planktonKriesel is

Kriesels are used for plankton as well as jellyfish. Mine however will be used to propogate the blood red shrimp passed its first stages in life (very delicate) i have attached a picture of a manufactured Kriesel(hope it works) used for jellyfish. it is true that people, especially shrimp breeders use a 20H and modify it. but i would like to do this project myself...and do a good job. I would also like to show you a picture of a dream kriesel but it is copyright protected so I will give you the website.

again THANK-U


well that attachment did not work so here is that site

Thank you for the picture, I understand what you are trying to do.

Can you make a square, then put a piece of acrylic over the corners making an octagon, then put more acrylic over the corners so you have 16-sides?

K-mac has the most massive acrylic tubes on the net. Your 24" tube is only $3,224.20 for a 4' long section. Enjoy!

 

[Bubbashrimp]

did you see the cloth type covering on the returns? Is that just...what do you call it again... but its measured for example "it has holes blank microns in diameter" well i forgot the general name for that. Anyways do you think it is held on there with marine epoxy

 

[Bubbashrimp]

well back to the drawing board as they say. Thank-u for the hot tip ChemE, maybe its for the better anyway i did not know it those surfaces would even bond.
