For those saying this is cruel, how is this any more cruel than a fish tank, or a dog or cat for that matter...
This is AWFUL! So these jelly fish live thier entire lives in a gallon container on a kitchen counter! Truly disgusting that you would think this a good idea!
I only hope now that there is a class action lawsuit so we can all get our money back from them.
anyone here has active contact information?
If yes, where do you have the bill from?
I'm from germany and my jelly tank is readya to pick up at customs but they don't give it to me without a bill or something like that...

https://www.amazon.com/HitLights-Multicolor-Strip-Remote-Controller/dp/B00BD8PM1U/ref=pd_sbs_60_41… I have been searching, but haven't found a source for the light bar itself. I will keep searching and post if I find it!
btw im an early bird also but i live in canada
@Michael Topper- I recommend switching food and ditching the Ocean Nutrition Food Instant Baby Brine that came with the tank, and using either the frozen food sold by moonjellyfish.com or the dried JetFuel sold by jellyfishwarehouse.com. Sunset Labs has informed me that the instant baby brine isn't effective nutrition for jellyfish and hard on water quality and filters.
I'm now using dried food and it keeps for much longer than the jarred stuff. Plus the uneaten food sticks together in larger clumps making it far easier to siphon out.
https://www.amazon.com/gp/product/B078XQ3FCL/ref=oh_aui_detailpage_o07_s00… The pump should be suctioned to the bottom of the tank (in the back, of course). It's a huge pain in the ass to get it down there, but this is critical, I haven't had any issues with stuck jellies since I put it down there. If you use the pump that came with the tank it's too weak, when it's attached to the bottom of the tank it barely has enough power to get water all the way up the tube and you'll get a trickle of water coming out of the spray bar. Honestly since I changed the pump the jellyfish don't really get anywhere near the filter slits or spray bar anymore, the current keeps them away. I keep the water level somewhere between the top of the filter slits and the spray bar. Not sure how much that matters, but keep in mind the lower the water level the harder the pump has to work to get water up to the top. It took me a long time to get the water quality stable and I had some issues with spoiled food. I'm still not entirely sure how to tell when the food goes bad (the smell gets pretty rough but to be honest it never exactly smells good), I've taken to just buying a new jar every 4 weeks and throwing out the old one. I lost one of my jellies a couple months ago (I think to spoiled food) and the other two shrank quite a bit due to the various food and water quality issues. The one just died this week, unfortunately I think it was only a matter of time because she had shrunk away to almost nothing, but she hung on longer than I expected. My 3rd jellyfish is considerably smaller than he started but doing well, and the water quality has been near perfect for about a month now so I finally ordered him some friends off moonjellyfish.com, they should arrive tomorrow. Oh, and I'm guessing it's been mentioned before but everyone NEEDS to buy a saltwater testing kit. I recommend this one, super easy to use:
Hopefully that link takes you right to the saltwater kit, but note that there are a bunch of options under 'style' so make sure you pick saltwater. I also recommend a refractometer, the swing arm hydrometer that comes with the starter kit can be a little unreliable. Here's the one I have:
https://www.amazon.com/gp/product/B005ES6MOQ/ref=oh_aui_detailpage_o07_s00… Sorry for the huge post, but hopefully this info helps some people. Also check out http://www.jellyfishcare.com/ and https://www.moonjellyfish.com/ for tons of good info on cycling, water maintenance, etc. I'm happy to answer any other questions to the best of my ability.
The tank seems to be available for retail sale on their site, and I can't imagine how long that could go on if a majority of the tanks have this problem.
To me this means either the pressure out of the individual holes isn't high enough to repel the jellies before this can happen(underpowered pump), or the spraybar design does not maintain equal pressure across all the holes, allowing for "weak spots" to occur(bad design).
I also think the holes are probably too big. If you look at other spraybar designs they usually involve protruding nozzles with smaller round holes.
I have my doubts about the efficiency of the mechanical filter as well, but that's a separate issue. I do think cutting two pieces of that plastic mesh matching the filter pads and placing them in with the pads between the pads and the main tank chamber would prevent the jellies from being stuck or sucked through.
I'm confused the lack of consensus regarding salinity- the Jellytank instructions say 30-35ppt, Jellyfishcare.com 32-35ppt, Moonjellyfishblog 31-33ppt, and Jellyfishart says 28-32ppt, so I've been trying to keep it pegged at 31-32ppt.
I checked out the mesh video and it looks promising for covering the filter intakes as in the video, but not so sure about the spraybar. I worry the thickness of the mesh might redirect the spraybar flow too much.
It's difficult to explain without visual aids, but my solution was to take an archival mylar(inert and non-reactant) sleeve- the kind used to store/preserve expensive comicbooks. I cut a 7" x 3.5" piece using a corner of the sealed(blunt) bottom to form two sides. Then bent it in half lengthwise 1" from the open end, really pressing hard to get a uniform fold. The mylar won't want to fold so you need to use a hard straight object- I used a metal ruler. Then I opened it up slightly and laid it on top of the spraybar with the 1" portion on top(the top of the spraybar is pretty much exactly 7" x 1") and the 2.5" portion hanging down into the water. Make sure this is the blunt sealed end of the mylar as the cut edges are very sharp. Position it so the fold in the mylar is right up against the front-facing top edge of the spraybar. This creates an angled tensioned barrier pressed against the curved side of the spraybay, but protruding about 3/8" past the bottom. Then I took a piece of U2 Fluval filter foam and cut a piece about 1" x 7" and pressed it between my mylar "flap" atop the spray bar and the inside top of the tank overhanging the spraybar. This keeps the mylar from moving as the spraybar flow pushes against it. The theory here is that A) the flap keeps the jellies from getting close enough to a spraybar hole to clog it, and B) also makes the spraybar current more uniform along the gap between the mylar and the rear tank wall(hopefully mitigating any partially clogged holes). My one initial concern was that even the blunt sealed edge of the mylar would be too sharp for the jellies(I originally envisioned making the flap using teflon tape), but so far so good. The flow strength of the water may be dulled slightly by the flap, but still goes straight down over the intakes. I thought I might need to increase the pump speed by one click, but again- so far so good, so I've left it alone.
Sorry for the long post. A pic would've made it so much simpler. The materials cost was negligible- the Fluval filter pads cost 91 cents a pair, and 4 mil Mylar(NOT Mylite which isn't rigid enough) bags are $22 for 25- both on Amazon. I happen to have both lying around. Now I have to go buy mesh...
Hey, I was reading on a Jellyfish forum, and a lady posted a video about how she fixed her JFA tank, after her jelly got stuck to the filter. Someone from JFA suggested this fix, and it has me thinking.... I wonder if we could suction cup a piece of this mesh over the spray bar? I got in contact with the lady, and the mesh came from a craft store (Michaels) and is usually sold for cross stitching. It would take some experimenting, but it would be an inexpensive fix.
I feel the same way about the tank in regards to all the extra costs. I suspect saving for an Orbit 20 may have been the better way to go, but I'm not sure the notion of owning a jellyfish tank would've ever occurred to me if I hadn't stumbled across this kickstarter campaign.
And after reading many bad reviews here is it possible for me to get a refund instead?
Clogging of some kind could be an issue, but I would think any disruption in flow would be noticeable by looking at the speed the jellies are moving. Which setting is your pump at now? Still 2 clicks below max?
My guess is that it's more likely algae or other debris is causing uneven flow through the spraybar holes- which all really need to spray at the same rate.
I wonder if anyone makes a pump where the speed control was on the cord so it can be changed without having to pull it out of the water.
Water change itself went ok, but can't believe how dirty this thing gets in a week. I've also switched food from the instant brine shrimp that came with the tank to a dried type from jellyfishwarehouse.com. It's been making cleaning up the uneaten food a bit easier- tho I did end up ordering a longer replacement device for the far-too-short turkey baster. Every time I stuck my hand in to get stuff on the bottom, it threatened to overflow the tank.
I can't imagine it would be salt causing clogs since in theory it's supposed to be well-dissolved head of saltwater going in the tank. I mixed my first change gallon a few days before use and just mixed enough for the next two weeks.
Unfortunately I did lose one, but that was my fault and unrelated to the spraybar, Today will also be my first 20% water change, so I'm going to ladle the jellies into a holding container so I can also clean the tank.
@ErinAshley Hall- I found the staff responded readily to any simple questions, but go silent regarding any inquiries that might result in having to admit there are problems with the tanks.
BTW, one thing I did in prep for getting the tank having read about the leak situation was look for a pan/base for the tank that could catch any leaks- the room the tank's in has hardwood floors. I found a lab equipment retailer called New Pig(newpig.com) that sells a "mini drip deck" that's perfectly sized for the jellytank. It's a raised hollow plastic base with a grated top and holds up to 1.5 gal of water- so almost a 3rd of the tank's capacity. Anyway more of an FYI, as I'm not sure how many people out there want to put even more time/effort/money into this thing.
I thank you for what you two are both doing. Your posts are more insightful and you are both more active on here than the creators.
I finally got my tank mid-last week (wrong color despite assurances from Blake that my tank was ready to go). A bunch of stuff also 'leaked' everywhere inside and of course, now I am waiting to hear back from someone in the office on what to do.
Before they stopped responding this last round, I tried to ask how to avoid the jellies getting stuck/shredded; their response was that it was not an issue that had come up during their testing & said they couldn't speak as to why......
Judging from others, I can only assume I will run into some operating questions and concerns going forward, but I wanted to say to you both that I really appreciate your comments. Fingers crossed, we can all learn from your experiences so far.
Thanks for the update! I sure hope it's a simple fix like you are thinking. I really like the look of the tank, and want it to work!
Due likely to the flexibility of the acrylic walls of the case, there's a slight amount of warping/flexing going on- which might only happen when the tank is full, keeping the spraybar from staying 100% flush against the wall of the tank. This is creating a small gap between where a slight vacuum is being formed- due to either suction from the back section through the hole the spraybar is being installed, or some kind of local "vortex effect" adjacent to the spraybar holes. This would likely vary between tanks depending on the manufacturing tolerances of the spraybar. It must be a relatively low probability for my tank as I've watched my jellies get right up to the gap and be pushed away by the spray bar. I'm guessing a jelly's tentacle would have to get wedge up there to a certain point in order to get stuck and then the suction progressively pulls them further in.
In any case, the solution would seem to be to add a rubber washer/gasket on the rear section spraybar fastening point to make it 100% watertight, OR adding a rectangular rubber or foam gasket between the spraybar and the tank wall in the front section- thereby sealing the gap across the entire bottom lip of the spraybar. I actually think lowering the water level, as some people have mentioned trying, may actually make the problem worse as it disrupts the circular waterflow being assisted by the curved leading edge of the spraybar.
I guess I'll watch and see how frequently its trapping my jellies and perhaps attempt a repair/mod- which would definitely require temporary removal of the jellies.
Since you've replaced both the pump and hose, have you had occasion to remove the spraybar?? Curious if you or anyone else in the comments knows how it's attached.
