    I would love to get ideas of what others use for various purposes in a pinch (bonus point for less than glamorous things 🤣) please share yours. 

     

    Yes that's me 🤣

    I am using a reuseable coffee filter with foam backer rod hot glued to it as my breeder box. Once the eggs hatch I feed plenty of sera micron and being so close to the light there is plenty of algae growth in the 'box'. Eventually they get live BBS until they are big enough to join the tank. Blue atm since I add a little methylene blue when the eggs first go in.

    My Medaka have eggs! Daily BBS continues to live up to expectations. When Dean one said "I doubt there is a successful breeder that doesn't hatch BBS daily" My experience continually confirms this to be true. The spawning mop is now in and I am ready for harvest! ٩(❛ᴗ❛)۶

     

    I love keeping medaka and least killies together. They are such chill fish that will eat right out of you hand.

    DIY Brine Shrimp Hatchery

    in General Discussion

    Posted · Edited by TheDukeAnumber1

    It's just a heater. The bottle is an old jack daniels bottle I cut the bottom off of, I feel more comfortable having a heater in glass. I hot glued a piece of ACO tubing into a hole I drilled in the cap and attached a valve that runs to an air pump. It functions the same as the ACO ziss hatchery just with a glass jd bottle and terta heater. The stand is a few pieced of wood screwed together and a ring of pvc pipe screwed on to hole the bottle.

    3D printer plastic for aquariums

    in General Discussion

    Posted

    I would want to see those papers if you can find them, it goes against my experience of having large PLA prints in nano aquariums where the animals remained healthy and I didn't have algae issues. And I have actively tried to get PLA to degrade in aquariums over long periods of time to see if it would under some circumstance without success. So maybe those papers would uncover why I haven't had those issues.

    I get what you're saying about ABS, I was thrown off by your wording as 'best' but yes it does have some nice properties.

    PLA, ABS, and PETG, probably the three most popular filaments, are generally aquarium safe. I've tested PLA from reputable brands in my aquariums for years at this point and haven't noticed water quality affected by it or degradation of the plastic.

    ABS is by far the best material to print with, but it's not a simple material to use as it does off gas during printing some noxious stuff. Enclosures with venting are ideal, as well as to regulate the printing area ambient temps to prevent warping or lack of adhesion of the print to the print bed. Be sure not to use chemical adhesives to promote printing when printing for aquariums. 

    ??? IMO ABS is one of the worst. If you've waded a ways into 3d printing and want the properties ABS offers it's fine, but like you said with the fumes and extra care needed to prevent warping...

    Adding PLA products to the tank result in algae blooms.

    Wow that's bizarre, I haven't had any noticable issues with PLA causing problems in my aquariums, even experimenting with an "exotic" brass filled PLA. I do agree that not all PLA's are equal and I think it is important to get quality PLA for a reliable source. And I do agree PETG is a good way to go too.

    Nobody makes tank separators well. At least none I've seen. I have been using a sponge to seperate my fry tanks. It's probably the closest to perfect I have seen for any product, but very young fry still are able to swim under it. 

    I know youtube has some videos of people making their own, but I don't trust myself to do those well enough. I'm wondering if a 3D Printer might be the answer. What I'm invisioning is to 3D print a frame to size. Then cover it with a material. I can't think of what it's called, but I'm thinking that material they use for some sewing hobby. Ugh I can't describe it well right now.  

    Does this sound like it may work? I'm not entirely sure how it would alll come together. It's more an idea without all the specifics. 

    I do think this could definitely work but you will need to pick up a little CAD, tinkercad would get you through this project no problem. I don't think a 3d printer is a good idea for just a one off project but if you do get one imo you would find it useful for aquariums in general and other misc things too.

    3D printing is a wonderful addition to a lot of hobbys. When it comes to aquariums you're going to need to use the right material though. Material science is key because some plastics used in FDM printing are biodegradable, others leach out toxins, others react with water as a solvent, and others warp with heat or moisture and heat. The thing about 3D printing as well is it's not as easy as buy a printer, material and you're good. There is a handful of tuning involved for each printer profile, material profile, and depending on the size/orientation of the prints custom support profiles. I'll also add, depending on the room your print in, temperature and humidity affect the spooled material, so you might need to invest in an enclosure to manage the environmentals of the material OR the print area while a job is being worked on.

    I agree and those are fair warnings, but imo if you buy a halfway decent printer and use PLA filament, everything is going to be fine for aquarium use. There are decent & not crazy pricy printers out there that have pre-setup filament profiles too and won't require much tuning. There is no 100% plug n play FDM printer but some machines are near it with their features and profiles and imo it isn't difficult to get halfway decent PLA prints.

    Interesting, some very mixed reviews having your issue. I have had bad rolls of filament before but never one that bad, and would go as far as to say what they are selling isn't always PLA. IMO bad and failed prints waste so much time and cause so much frusturation that high quality PLA is worth the increased price.

    As crazy as it sounds, my PLA will actually degrade in a aquarium after 6 months. It starts getting holes in it and breaking apart. Also, a little off topic, but I 3d printed a custom soap dish for my bathroom sink, and after 8 months, it is all cracked up and falling apart.

    Can I get a link to the PLA you are using?

    PLA, ABS, & PETG, the filaments used in the vast majority of prints are all aquarium safe. I wouldn't think twice about putting any of those three types of filament in my aquariums.

    @Guppy Guy

    PLA is only biodegradable in special industrial settings. I've had PLA prints in my aquariums and garden compost for several years with no signs of degrading.

    Little teeny bugs in aquarium

    Those look like some type of ostracods to me. 

    AKA, algae control and fish food. 

    I actually buy them and introduce them to my tanks. Harmless, unless you're algae.

    Ostracods are aquatic but these were described as hanging out on the surface, glass (photoed above the water line), and jumping.

    This thread may help identify.

    My guess is that those are springtails. I've had those before and they didn't cause problems or leave the aquarium, tbh I sort of enjoyed them. But if you want to get rid of them I would suggest regularly skimming the surface of the water, wiping down the glass, maybe increase water flow at the surface, and deny them any floating plants or structure. You basically have to create a non-ideal environment for them until they die out.

    Edit: and to my knowledge they stay on the surface and don't go under the water, so maybe using a hair dryer would be enough to over heat them and take them all out at once ¯\_(ツ)_/¯ (I would be very cafeful to not overheat the glass so it doesn't crack due to heat stress, but it may work)

    Not the ones in the image itself, however a different gcode file (that is essentially just a mirror of the parts in the pictures) came out quite well 

    Sry for the slow response, been a busy week & weekend. If I am reading your notes correctly it looks just like a Z seam issue, which there can be a few causes and a few solutions. I believe Cura has options for z seam alignment, I would try "sharpest corner" but the "random" setting may work too. I've never messed with retraction settings but I understand that to help solve z seam issues. Also overly hydrated filament can cause a little over extrusion too.
