"Does the single spraybar really create the flow all the way around the tank?" Yes. It actually works very well. Make sure that you have a valve on the return pump to regulate the flow. I highly recommend using a gate valve. They are much easier to control than the cheaper ball valves and you do need some pretty accurate control for jellyfish aquariums.
We have sectioned off the tank so that the place where the actually jelly fish will be is like rectangle tank but tall. We had acrylic pieces cut to make the curves to create the circular flow as you did in your video. We are installing the spraybar to push the jellyfish gently around the tank.
It is a tall 45 gallon Hexagon tank. We just got our acrylic pieces from the plastic shop. We are going to get the mold made to make the curved pieces and should be able to get them installed this weekend. We were able to get the purple led lights we wanted for $2.50 ea, we have 4 total that we have enclosed into the plastic tubing. Again we would still be stuck trying to come up with a plan if not for your video, you rock!!! We are taking pictures of the progress and will post once we are done!
We are in the US and the moon jellyfish is now what we are looking into getting. But we are still no where near (but a little closer after seeing your video) ready for them. We are sectioning out the tank so the jelly fish will have about a total of 15 to 20 gallons to float in. the front section we are going to add a little sand, coral and a couple of little fish. We have the back sectioned off that we are designing a spraybar a filteration system. We are slowly but surely figuring it out.
Ok first off I have to tell you that you have the best video for jellyfish that I have watched! I have a couple of questions. What type of jellyfish do you have and where did you buy yours? What size of tank is this? My son has a 45 gallon hexagon tank that he wants to turn into a jellyfish tank. While I know all about the filtration system, the part we are stumped on is getting the flow right. Does the single spraybar really create the flow all the way around the tank? TYIA for any help.
Thank you for the kind words about my video!! What type of jellyfish do you have and where did you buy yours? I have Moon Jellyfish (Aurelia aurita). For keeping in aquariums, I'd recommend getting jellyfish only from tropical climates. I got mine from a wholesaler in Hawaii. If you're in the USA you can order them online from a number of different sources. If you're in Canada, you're kind of out-of-luck. If you are in Canada, send me a private message via UA-cam and I might be able to help you
Very well done, impressive diy build. Do you think I can do this in a 40 breeder (dimensions LxWxH is 36x18x16) Do you think a 18" wide tank (with otherwise same dimensions) would work as well, as long as the spray bar and outtake are scaled?
Wow, it's been awhile since I looked at this video and the comments/questions. I'll answer the most recent below. If there are questions I haven't answered, just post them. I am starting my next jellyfish project shortly. It's a 42” tall 100+gallon tank. More to come about that. “Does this tank produce algae? Is so how do you clean if tank is sealed?” Not much algae grows. Moon jellyfish require little/no light. So, the lights are only on when someone is looking at them. As well, jellyfish require quite clean water. So the Nitrate and Phosphate levels (which algae requires to grow) always run quite low... close to 0.0ppm. A bigger issue than algae is a light/white film that develops on the inside of the glass that needs removing (just a wipe with a sponge or algae magnet) every few days. Access to the tank isn't a problem. It isn't sealed. About 2/3 of the top of the tank is open. “How much did the whole thing cost u?” Most of the stuff I used in the project I had around the house. So, it didn't cost me much of anything. If you were to go out and buy the aquarium, acrylic, pump, filter media and so on, I'd guess it's run between $200 & $300. Not including the jellyfish. The most expensive part was shipping and importing the jellyfish from Hawaii to Toronto. “What tape is that used to hold in the acrylic ramps?” It's not tape holding the curved corners in, it's little pieces/tabs of acrylic held in place with e6000 adhesive (awesome stuff). The corners just snap in place behind the tabs. “Have you had success keeping them alive?” Yes, success is easy. Moon jellyfish actually aren't that difficult to keep. All you really need is good water chemistry and an aquarium with the correct flow/current pattern. The hardest part of keeping these jellyfish was keeping a constant supply of newly hatched baby brine-shrimp. I start a new batch in the hatcheries every two days. Moon jellyfish live for about a year in the wild. Often times, they live a little longer in captivity. The longest lived of these was 18 months. Now, I a setting up a bugger tank and doing it again. “Where did you buy your jellyfish because it seems most suppliers require that you buy their own custom tank in order to be supplied the Jellyfish.” I got them indirectly from an ornamental fish wholesaler out of Hawaii (Wayne's Ocean World). I piggybacked them on an order going to an aquarium store that have been affiliated with. You might be able to contact them and find out if there is a pet store in your area that they ship to and then try ordering them through that store. There are a few websites that you can order jellyfish from in the USA. Living in Canada, I don't know much about them. They seem to only sell small ones though. Even the ones that they label as large, are small compared to the ones that I've kept. If you live in Canada and want Moon Jellyfish, I can get them for you. “Ok that is awesome! I love it! “ Thank you!! I love it too. :-)
I would love to see pictures or video of the tank with the new modifications. Is that possible? Also, can you please provide more detail about the chamber behind the filter? Dimensions, water height, etc...
Most jellyfish eat the same thing. Baby brine shrimp, mysis shrimp, jelly fuel (must be presoaked), and copepods are all good choices. Just make sure that any uneaten food is cleaned out of the tank after an hour, that their stomachs are full at least once a day, and that the tank is cleaned regularly.
How much maintenance does a tank such as this require? I don't want to get into the saltwater game (fish and coral) due to the stress, attention, and care the tank constantly requires. I don't have the time, money or equipment for a project like that. How does a jelly tank compare. Does your Ph have to be spot on or shit starts dying like a coral tank? can your temp fluctuate? How much personal time do you put into the tank other than sitting and enjoying it's beauty? Sorry for all the questions, I just want to know what I'm getting into before I start a new hobby. Thanks.
Hi, I am thinking of buying a second hand 46l fluval edge tank and keeping some moon jellyfish. I spoke to a couple of companies today and told them what I was planning, cutting some clear acrylic triangle bars and siliconing them in the bottom edges of the tank. All the pump, filter, media and heater are in the column at the back of the tank so not inside, the only thing that comes inside is a return tube. My only concern is the flow, to keep the jelly fish from just laying on the floor, my only idea is to extend the return tube to the bottom of the tank and then again using a semi circular tube to cover the return pipe, so the jellyfish don't go near or around the back of the tube. Do you think this would work? Also I am not planning on using a protein skimmer, just sponge, charcoal and bio balls, what's your opinion please. Thanks in advance.
"What size of tank is this?" Standard 35(ish) gallon rectangular aquarium. 36"Lx18"Hx12"W. I believe that there is a taller, 40 gallon rectangular aquarium that's 36"x18"x18" (or something like that). If I were to do it again, I'd use a taller tank.
Generally, you won't need a heater in a jellyfish aquarium. Most species will do fine at room temperature, or a little bit cooler. the most common jellyfish species, moon jellyfish do fine at room temperature. if you were keeping a species that required higher temperatures like the blue blubber jellyfish, a small heater would be required. In this particular tank, if you wanted a heater in it, it would be easy. You could just put it in the chamber that the pump is in.
Have you had success keeping them alive? Where did you buy your jellyfish because it seems most suppliers require that you buy their own custom tank in order to be supplied the Jellyfish.
Since I posted the video, I've made some modifications I added another round corner in-front of the (old) intake Rotated the spraybar 90 degrees so it is now pushing water across the waters surface Moved the intake screen so that the intake is now at/along the waters surface This way the jellyfish have already made the corner before they get pushed past the intake by the spray bar. And, gravity helps too. With the old design, they had to turn the corner and avoid the intake all at the same time.
"Turn a 45 gallon hexagon tank into a jellyfish tank." I don't see how you'd make a hex tank work for this. It's entirely the wrong shape. You hear people saying you need a "round tank" or a "tank with no corners". There are a lot of misconceptions about this. You want no corners and a circular flow on a vertical plane. Tall cylinder tanks, although they look good do not make the ideal jellyfish tanks. The vertical cross-section of a cylinder tank is a rectangle with 90degree corners.

Ok.. now I understand how they can command so much money for a tank. I was going to build myself one. Good job! :) very mesmerising.

“Ok that is awesome! I love it! “
Thank you!! I love it too. :-)
Please do a DIY video and show us how to build this :D I’ve searched and searched and there’s nothing like it on the internet, you’d be the first
I seen these at the Musium the other day so awesome
I would love to see pictures or video of the tank with the new modifications. Is that possible? Also, can you please provide more detail about the chamber behind the filter? Dimensions, water height, etc...
GOOD LUCK WITH IT!!
The tank looks amazing. What do the Jellyfish eat and how do you feed them? Thanks
Most jellyfish eat the same thing. Baby brine shrimp, mysis shrimp, jelly fuel (must be presoaked), and copepods are all good choices. Just make sure that any uneaten food is cleaned out of the tank after an hour, that their stomachs are full at least once a day, and that the tank is cleaned regularly.
Also don't target feed them, the way they eat is usually by swimming past it and it gets caught in their tentacles.
Nice tank!

This is a nicely made DIY tank, but I would suggest getting rid of the bio balls, the jellyfish are reall
Ok that is awesome! I love it!

Does this tank produce algae? Is so how do you clean if tank is sealed?
how much did the whole thing cost u?
How much did the whole set up cost?
Whst tape is thst used to hold in the acrylic ramps?
How do you get the water circulation?
With a spray bar I believe
Can you make an updated video with your new changes?
What kind of tank is this?
DOES A JELLYFISHART TANK NEED A HEATER AND IF SO WHERE DO YOU PUT IT????? I AM PUTTING COMB JELLIES IN THERE

Have you had success keeping them alive? Where did you buy your jellyfish because it seems most suppliers require that you buy their own custom tank in order to be supplied the Jellyfish.
Nice tank! Just remove them into a round tank. They can be kept in fish box but u have to set up a filter. Actully U MUST
By making these modifications, the flow in the tank is now running in the opposite direction.
Well that's too much work...better stick to goldfish lol
do jellyfish blow bubbles?
no
why it doesnt have any rocks or nothing just jelly fish? why?
jellyfish are really really delicate animals. Even the smallest contact with something can kill them.
@@DillonBorges Their delicate but the smallest contact wont kill them. They run into things all the time.
Telly sensitive and bio balls cause a spike of nitrates. Sorry, im on my iPad and I accidentally hit enter.
omg you have pet jellyfish?!?!?!? If so can I kidnap one
Since I posted the video, I've made some modifications
I added another round corner in-front of the (old) intake
Rotated the spraybar 90 degrees so it is now pushing water across the waters surface

I would like to keep jellyfish as pet but, to maintain the tank is hard. I guess, betta fish is enough for me.
Cool! Although jellyfish need a round tank they can get stuck in the corners and die. O_O

Google "kreisel aquarium" to get an idea of the type of tank and flow pattern you are trying to achieve.
