Introduction: Cheap Sea-Monkey Aerator!

Picture of Cheap Sea-Monkey Aerator!

I've always been a big fan of Sea-Monkeys and I seem to never be able to come home from a trip to target without a new Sea-Monkey tank. A big part of keeping them alive is having enough oxygen in the tank. Oxygen gets in the tank by aeration. The sea-monkey guide that comes with all of the new sets recommends pouring the sea-monkeys into a cup then back to the tank to aerate the water. But that's time consuming and is just asking for you to spill them. The only other alternative is to buy the "Million-Bubble Air Pump" which is $3 plus shipping. I will admit that I have bought the pump before (then it was thrown away when it broke) but my simple Instructable aerator is much better then the pump. And cheaper!

Supplies you'll need:
Sea-Monkeys/Tank (I'm totally judging you if you didn't know this already)
Straw (preferably the bendy kind. And not some cheapo ones you got 200 for $1. Those will rip and not work)
Stapler (Swingline. Red preferred)
Staples (I'm getting sick of spelling things out)
Staple remover

Step 1: Staple and Remove

There really is basically only one step to this project, but we'll stretch it out for fun and longer loading time! At the end of the straw (not the top part, with the bendy) take your stapler and staple three or four staples. Don't make them any higher then about and inch and a half from the bottom of the straw. Then remove the staples. Then do this again, stapling three or four and removing them. Then rotate the straw 1/4 and repeat from the beginning. At the end of your last removing you should have stapled and removed 4-5 times. With quite a bit of visible holes. If the straw ripped, try again. If the straw continually rips, buy some higher quality ones. If that doesn't help be more careful when you are removing the staples.

Be careful when you are stapling. Blood=bad. Bring all necessary fingers with you to the hospital.

Step 2: Finishing Up

When all of the staples have been removed you can use it as an aerator for your tank as it is. Or, for more variation in bubble size you can put a single staple (not to be removed) horizontally (going the same was as the straw) in the middle of all the holes (see photo). I do this because it allows for better bubbles, but you don't have to. The aerator is now ready to use. Just blow lightly on the end with no holes while the end with holes is in the water every day for about 2-3 minutes (more in the first few days of sea-monkey life) and you'll have thriving sea-monkeys!

A note: when you are done aerating your tank blow out the straw to make sure there are no sea-monkeys stuck to it. That would be sad. *sad face*

CO2 is actually harmful and poisonous to Sea-Monkeys. The older, larger Sea-Monkeys may be able to cope, but there's a chance that your baby Sea-Monkeys will die.

Very little gas is dissolved in any liquid via bubbles. The gas exchange happens at the surface of the water. The bubbles just help break the surface tension allowing the water become oxygenated. CO2 from your breath will not negatively effect the water.

Just because I can think up a name more interesting than 'kmiller25' doesn't mean I'm uneducated on the subject of Brine Shrimp.
I'm just saying-- use this at your own risk. It's your choice. I'm just simply putting my view and experience out there. When did that become illegal?

Dr.Squirrel (author)2010-12-30

Why can't you just use the Aqua Leash that comes in most sets?

Pizzapie500 (author)2010-01-26

Why won't you just use one of those push pins? They are better than taking a staple out then putting one in. A needle might work too.

airsoftingmaster (author)2009-08-09

u can stick the straw 2 the aqua leash so that there is no carbon dioxide going 2 be blown into the water. but u hav 2 make sure that u are not pumping water instead of oxygen

joeanne (author)2009-05-23

The see monkeys would get oxygen from blowing through a straw. Cause people give CPR to people who have stopped breathing and that gives them oxygen so they don't die.

mjarthur (author)2008-09-22

your is the only project that came up for a search of brine shrimp, any ideas on making a larger set up? ive got the lil store bought sea monkey set but ive always wanted since i was a kid to make a big 10 gallon set up of them lol

sam432fat (author)mjarthur2009-01-01

i read comments and forums on many websites and people really don not reccomend anything of 2 gallon i dont know why tho

Aqua-Man (author)2008-10-31

so are you saying you blow into it with your mouth wouldn't that be adding carbon dioxide not oxygen

shanshan (author)2008-10-08

so does that mean you just add holes at the end of the straw? Could it be possible to use a needle or somthing sharp to pierce through instead of using a stapler?

sgt.paper (author)2007-07-24

what the hell do sea monkeys look like!?!?!!?!?!?!?!?!?!?!?!

my Sea Monkeys never got that big!

sgt.paper (author)Camel_Doughnut2007-07-24

ooooo thanks

badrang4 (author)2007-08-09

hey i kno a really cheap brand of sea monky just ask ur loacale pet store for brine chrimp for feeding!

pmac93 (author)badrang42008-01-22

yeah but real sea monkeys are genetically modified so they grow 3/4 of an inch long.

Guppy8 (author)2008-01-14

okay, well, it would be pretty obvious if it works, so I believe you. I was just curious.

Guppy8 (author)2008-01-13

won't blowing in the straw just make the tank full of carbon dioxide and not oxygen? You exhale co2 not oxygen.

Camel_Doughnut (author)Guppy82008-01-13

Nope, you do exhale enough oxygen that the sea-monkey's will get a lot of benefit from blowing the straw.

Yakster (author)2007-09-14

This is great, I've been using this at work and when we transfered my daughters sea monkey set into a large glass to move out while our house is being fumigated we're using this because her aerator is too short.

I fit a second straw into the first for a longer reach and I also fold over the end of the straw with the holes before I add the staple a the end to make sure that the bubbles are small and don't disturb the tank too much. There's two staples shown because the first one missed the flap.

I also was lazy on the second one I built and just punched holes in the end of the straw with a pushpin into a folded napkin instead of repeatedly stapling and removing staples.

The sea monkeys in the picture are four weeks old in the Executive Sea Monkey set (because it came with the million bubbles aerator which I now no longer need).

Thanks for the great idea!

i kno i spell bad but im in a hury

Camel_Doughnut (author)badrang42007-08-10

I forgive you.

brainiac (author)2007-06-25

for some strang reason my sea monkys wont come out of thier tinnie eggs any advice?

brainiac (author)brainiac2007-06-25

should i add salt to their water?

Camel_Doughnut (author)brainiac2007-06-25

Nope! Adding salt will kill them! The water purification packet that you added first provides the required conditions for the sea-monkey water! How long has it been since you put the contents of the egg packet (#2) in the water?

ozzfreak (author)Camel_Doughnut2007-08-08

you have got to be joking when you say adding salt will kill them. I have raised hatched them by the millions for my aquarium fish for years. take a look at this site.........

notice the part that says......
25 parts per thousand (ppt) salt solution, or approximately 1 and 2/3 tablespoons of salt per quart (or liter) of water. This equates to around 1.018 specific gravity as measured with a hydrometer. Be sure to use marine salt or solar salt."

Camel_Doughnut (author)ozzfreak2007-08-08

With Brianiac seeming to be a first-time or not totally studied in Sea-Monkeys (no offense to him, it just seemed that way) that is the best advice for him. And for you, I'm just relying what the instructions say. I've been casually buying sea-monkey kits for a while, and I have never added salt, because that really is not necessary. So thank you for the input but I am not "joking." Not everyone knows that you should put 1 and 2/3 tablespoons of salt per quart of water. And most of the time adding salt will in fact kill them, because the first packet has enough salt in it to properly allow them to hatch.

brainiac (author)Camel_Doughnut2007-06-26

I just put the eggs in mine didnt have the purification packet. I got ripped

Camel_Doughnut (author)brainiac2007-06-26

What set did you buy? Did it come with packet #3? Did you read the instructions on the back of packet #2 (the eggs)?

Kaiven (author)2007-07-28

hmm... they actualy arent monkeys...they're brine shrimp . read the first paragraph(at least)

brainiac (author)2007-06-25

i wonder how hydrogen will affect thier groth patterns

xmikeox (author)2007-06-02

I've never seen seacity for sale, anyways i've had my seamonkey setup on our windowsill and it's gotten to the point where there is so much algea that on a sunny day bubbles literally continually rise from it.

sleeping_gecko (author)2007-04-17

Sea Monkeys are great! I haven't had any for a long time, but they'd probably make the perfect college pet...hmmmmmmm... This is what I used when I had them, and it worked great.

JGB (author)sleeping_gecko2007-04-17

Great idea for creating small bubbles, BUT... wouldn't you be introducing carbon dioxide from spent breath and not oxygen? PEerhaps there is enough oxygen expelled... I don't really know. However it is worth discussion.

ningo (author)JGB2007-04-17

Roughly 16% of what we breathe out it still oxygen, so the above will oxygenate the water. Mouth to mouth resuscitation wouldn't work otherwise.

JGB (author)ningo2007-04-19

Good point.... good point!

andreq (author)2007-04-17

Blowing CO2 into water will help them ? Anyway nice instructable if you use some kind of cheap air pump and this straw... Could always replace the "not so cheap" fish tank "bubble generator" (the black or blue "rock alike" thing you put at the end of a tube to generate little bubble..)

CameronSS (author)andreq2007-04-17

The human lung is a startlingly inefficient organ. The air we breathe in is about 21% oxygen. The air we exhale is roughly 16% oxygen. The concept that humans exhale pure CO2 is a myth.

sleeping_gecko (author)andreq2007-04-17

As ningo said (after your comment, I see), we do exhale some oxygen. Whether it's that oxygen in the bubbles, or the agitation, as LasVegas said, this device works. It worked fine with my Sea Monkeys, and with the author's. And a cheap air pump and straw could probably be a bad thing, since the tanks are generally pretty small, and even a little aquarium pump would probably overpower it. If you could get a small enough one, or even upsize the Sea Monkey tank, a pump would definitely work, though. Like in a normal aquarium.

I agree with sleeping_gecko. If even a small air pump were introduced in the tiny tank it would be a sad day in sea-monkey city.

jammis (author)2007-04-17

I just have a cat.... But cool instructable!

LasVegas (author)2007-04-17

Believe it or not, it's not the bubbles that aerate the water, but the agitation of the water (the waves). While bubbles are pretty, stirring the water is equally effective.

Sgt.Waffles (author)LasVegas2007-04-17

Actually, the oxygen from the bubbles disolve in the water. The bubbles that dont get disolved that stir the surface, provide more surface area for the gas exchange at the surface of the water. I dont see what is so cool about "sea monkeys". Sea monkeys are just brine shrimp. I feed them to my fish. Its not that big of a deal.

erfonz (author)2007-04-17

My sea-monkeys have been alive for a bit over a year and all I've done to them is feed them like once.

Camel_Doughnut (author)erfonz2007-04-17

They must have resorted to cannibalism if you've only fed them once.

Camel_Doughnut (author)2007-04-17

I should clarify something, on the last step where it says "I do this because it allows for better bubbles" what I mean is that when the bubbles are to big (the ones provided from the end of the straw are the biggest) the water gets too shaken up, and in the tanks you need to keep the water line very close to the opening of the tank. Bigger bubbles will provide more spillage of sea-monkeys and sea-monkey water. Which would still be a sad day in sea-monkey city. But this is optional and I recommend it to people who have never aerated the sea-monkey tank with a straw before as they tend to blow extra hard (I don't know why) and once again, a sea-monkey tragedy and more husbandless sea-monkeys who have to raise the kids themselves.
