      Has anyone successfully made a DIY remineralizer like Jay's one but for sulawesi? I'm interested to know, because if possible I too would want to make my own, but if nobody has experience with it, I'll get the Salty Shrimp mineral for sulawesi.

      Hi Everyone,
      I was inspired to make the stainless steel immersion tubes found in the following thread: 
      https://skfaquatics.com/forum/topic/9455-cooling-multiple-tanks/
      I made mine with the following materials
      - x metres of annealed seamless stainless steel tube grade 316. Outer Diameter 12.7mm, Wall Thickness 0.9mm, ASTM 269. I got mine from Midway Metals in Sydney for $5 per metre.
      - A hand bender, rated to bend thin walled stainless steel. Got one from ebay for $99.
      - A tube cutter, again make sure it will cut thin wall stainless steel. I got mine from ebay for $32.
      For 60cm tanks I recommend 3 metres of tubing
      For 30cm tanks I recommend 2 metres of tubing
      Your hand bender will have an inherent bend radius, using this you can calculate the length of tube that you will use up with each bend whether it be 90 degrees or 180 degrees and pretty much how much tube you will need depending on your design. 
      NOTES: I used 12.7mm tubing as you can then squeeze 12/16mm aquarium hosing on to it snugly (if you are paranoid use hose clamps as well). I also used 12.7mm OD tubing as its the maximum diameter you can get a hand bender for that is rated to bend stainless steel. Do not get thicker than 1.0mm walled stainless steel it will be a nightmare to bend. Make sure your stainless steel is annealed seamless tube this is specifically made for severe manipulation. This is for freshwater application only... the guys at midway said this would last 3 months in a saltwater tank lol. Good hand benders are each made for one specific diameter only, make sure you get the right one for your tube diameter.
      I am happy to post links to the ebay items if I'm allowed to.
      I'm pairing this with an Eheim 2213 and a Resun cl 200 chiller to chill 2 x 60cm tanks and ultimately 3 x 60cm, I'll update once this is done and give some feedback on the temp differences. I hope the info is useful.

      Hello,
      So I made this little tank and stand a few weeks back to go in my shed.
      It gets way to hot in here to have a normal co2 cylinder and I don't have a spare one floating around anyway, but I have lots of bits and pieces,
      So I made this:
       
      The reactor, Filter, night time shut off and proper needle valve to ensure the co2 level is constant and never rises.

      A diy wooden diffuser I made producing very fine pollen style bubbles.

      The only thing I would add if I could is a pressure relief valve, you can buy cheap kits off eBay that have one of these and a gauge, but this system doesn't seem to need it.
      Im also using a recipe I adapted from mycology research utilising sugars with more complex carbohydrates to give a more stable long term reaction, I started this recipe on the 28th of dec and it's still going strong.
      I had to remove the built in check valve from the other side of my needle valve (cause it's made for high pressure) it prevented co2 running to the diffuser at start up, and caused pressure to build up. I just used a standard air line check valve that requires less pressure to open and it's all working fine again. Atleast now I know standard airline push fittings hold up under the pressure, literally. I have used proper co2 tubing throughout, it's probably not needed considering this is a "constant" system but I had it laying around.
      The the solenoid valve which runs my "night time shut off" operates a bit different to a standard pressurised co2 system.
      I designed my solenoid on a T to the main line, It opens at night just venting co2 into the air instead of running into the tank, this is so pressure doesn't build up and wreck the whole system. 
      My fav part is the diffuser TBH,
      I'm so fascinated by wooden diffusers.
      enjoy.

      This is the new and improved steriliser. 
      its basically just 40mm pvc pipe end cap with spacers made from 40mm pipe.
      2 wires connected to mesh close together in the water.
      Splits the H20 on a molecular level, pretty cool for how simple it is. 
      Normal copper wire will work but it will dissolve within a few minutes, ive just used stainless steel BBQ skewers, these also worked well to just hang the whole unit from the side of the tank, and the stainless steel mesh from a tea strainer.
      Then air line tubing to prevent the rods touching, and some heat shrink to hold it all together, 
      You just have to do tight connections like unless you have a SS welder, 
      ?
      I'm just using 12v DC so in theory I could easily add a fader to control the intensity of the steriliser just like the fancy ones.
      I might do an actually write up on it later or something. For now I'm getting this bad boy in my zeb tank.
      its working great, now how long should I have it on for? Haha
      I was thinking starting at 15min per hour. Lol yeah it's pretty damn ghetto.
      Cheers

      Pretty sure everyone knows how to silicone rings together so won't be a step by step tutorial
      What was used was:
      Aquarium safe silicone or superglue Ceramic rings (choose an inert one and one that has a nice hole size for the specific shrimp you are making it for) I chose Mr Aqua M size. It is inert and quite porous for extra surface area (never a bad thing). You may want to look at getting the L size if you are making for large adult shrimp. Stick like a shish kebab stick to clear any obstructions that the silicone may have caused on the inside of the rings. They look quite nice I reckon, with moss on them will look even better!

      For around $15 you can easily make 10+ pyramids, go crazy and make them as big/small as you want, giant levelled pyramids or single logs, up to you!

      in this hobby we like to save where possible, so making these are a great way to save!

      yes, it's the shed shells. now that I think about it, I also remember in the video the bugs were clear, and I have seen clear ones before too, a long time ago.  But these recent ones were dark colored. So I have two tanks.  In one of them, where I normally have this problem, I have been dosing antibiotics.  The short version is that most of the shadow panda and RWP shrimp have got this disease, but they haven't died either.  But they don't recover either.  They just simply stop growing and stay at a small size with stumpy short antenna.  The first shadow panda that got this problem is still alive maybe 2-3 months later. In my other tank which often doesn't have this problem also got it, but it seems to have hit harder, where both "almost adult" shadow panda suddenly got it and died within a few days.  Antibiotics didn't save them.  It's too weird - it seems like this problem comes on suddenly, with no trigger that I can think of.  (besides "the weather was warm and I ran the air conditioned".  This doesn't actually affect the water temperatures since I have a chiller, but maybe something blew into the tank?)

      Sorry for the delay, I have been searching on here and the wider web but cannot find what you are referring too! I do know which video you are talking about and remember seeing it. The video was of a shed shell rather than a live shrimp! Are you seeing them on live shrimp? From memory I don't think it was anything to worry about and I very much doubt it would discriminate between different colours of shrimp, but was probably nothing to worry about and just part of the life in aquariums, like detritus worms and other life forms. I think they were colourless in the video, if my memory is any good? Are you still getting shadow panda deaths?

      Hello folks, I remember reading about this a few years ago but for the life of me cannot find this info / thread again. Can somebody point me to a link for this info? I forgot the forum I saw it on. There was a discussion about how if you look at a shrimp molt shell under a microscope or loupe, sometimes you can see tiny "bugs" or whatever moving around inside. At that time, I think the conclusion was that maybe it was a symbiotic relationship because it even happened with healthy shrimp. But I can't remember if this occurred only in neocaridina or caridina also? I just happened to look at a shadow panda's (caridina) shell who is sick with the "shortened antenna disease" that I always complained about. There were tiny blue/black spots moving around inside.  I also looked at the molt shells of some blue bolts that don't have this problem, and there were very few, or none, spots moving around inside the molt shell. I wonder if this could be some symbiotic relationship gone wrong and is the actual (proximate) cause of the problem.  (Since antibiotics didn't really seem to work) In that case, I would need some kind of anti-parasite medication to cure the shrimps.  What are the typical internal anti-parasite medications for shrimps?

      You may end up losing this batch entirely but then you can start completely fresh and get the aquarium set up right for the next batch of shrimp! If you do any large water changes then try and add the new water slowly, either dripper or some other way. You should get yourself a TDS meter (as JayC above), they are cheap and readily available. You should always use a GH tester kit as well with shrimps, if you do the 50% water change that should halve the GH so you should get a reading after that, or if you can get a local fish store to test it for you that will give you an idea of the GH. If your water supply is as hard as it appears it may be you will need to mull over how (or even IF) you want to keep shrimps as that may mean using RO or distilled/bottled water and buying a proper shrimp specific remineraliser? That will be quite expensive but you won't then have to mess about adding crushed coral/eggshells etc, but only you can decide whether you want to do/spend that much etc? If you live somewhere that gets a lot of rain, then you can use rain water? Also, as JayC states, you need to know what you are using/adding to the water and aquarium, ie fertilizers, rocks. Unless you have very exotic plants you shouldn't need any fertilizers. Just as a note, we have come across quite a few experienced fish keeprs that have this sort of start off issues with shrimp. Shrimp are more difficult than fish, and the aquarium and water etc need to be ready and within the required parameters before getting the shrimps. Usually people jump in, get the shrimps before everything is ready/sorted. Hopefully though you will keep at it, or if this lot die you will have another go and we can help you get it sorted?

      These are all classic symptoms of shrimp moulting problems.   Again, another high GH symptom. High GH not only causes harder carapace (shell), but it also makes eggs harder. When the egg is harder the male finds it more difficult to fertilise the eggs.   That's a worry if you can't get a good GH reading because that is going to be most likely issue right now for you.   Because snails don't moult.    If you dont already have a TDS meter, I suggest getting one asap. It's another test to narrow down your water parameters, and not have to trust one test by it's own - in this case the GH test kit. I would wager your water parameter is too high in dissolved minerals - likely from the tap water source, fertiliser dosing and/or any rocks/crushed corals you might have in the tank. To remedy this, you need to start doing water changes with RO, distilled or rain water immediately. I would do a 50% water change with RO water asap. Then look for sources that increase GH in the tank and eliminate it - fertilisers, rocks, crush corals, shells.    It's difficult to save a shrimp who's carapace is already too hard, but hopefully any younger shrimps will benefit from the water change and the reduced GH.   Good luck and keep us updated.
