      Anyone with very large, or many tanks will probably not be interested in this, aside from curiosity maybe, as I doubt this is cheaper than buying RO water. I am writing this purely in case it may help someone else who wants an easy alternative to RO water.
      I am housebound (have MS) and as such needed to find an easy alternative to RO water if I were to keep Taiwan bee shrimp successfully. I have red cherry shrimp in my 30L FISH tank (neon tetras, ember tetras, endler guppies) and they do well with virtually nil care (or attention since I mastered the TBs) other than dechlorinated tap water (which is needed for the fish anyway) so I won't go any further on that subject.
      About 3-4 years ago I set up a 15L shrimp tank and tried BRITA filtered tap water, but had no real success with that and so 2 years ago closed the tank down and stored it away assuming then that that would be it, no Taiwan Bee shrimp ever....... but after 2 years of no success, at that point it was a bit of a relief anyway to just be done and out of the way. You will see from the Tap water readings below that in theory the Parameters were pretty good but from my experiences I think you need to go back to NIL (so either RO or the zerowater) and remineralise as I guess that way you know what the tests are picking up is only what the shrimp need - this is only my belief I don't really know, but ie the tap water TDS (Ph, Gh, Kh etc) was ok but what was in the Tap water to make the TDS reading what it was, if that makes sense? I have read on many sites of people trying tap water , as I did, with good parameters but it not working so that is my theory anyway! And of course domestic water supply parameters can change and if there has been any repairs in the system that will change it etc so from my experience only way to go is take it back to NIL and remineralise.......
      A year ago (about a year after closing down the old shrimp tank) I came across a water filter jug from zerowater (www.zerowater.co.uk), an american product which I believe is available in Australia on Amazon, but may also be in shops out there for all I know). I thought, why not give that ago.... so I set up the old tank Oct 2017 (15L with the back part partitioned of for filter etc so probably 12L of useable aquarium) put some soil in and a few bits of Java fern and moss from the fish tank and ran it with the zerowater for a couple of months. I didn't ever get any Ammonia, Nitrite, or Nitrate reading but did see a bacteria bloom for a few days. I treated the zerowater as you would RO water, so added shrimp king mineral fluid gh+. There is a lot of info on the website about what it removes etc.
      Tap water PH7, Gh 5-6, Kh 3-4, TDS 174
      Zerowater Ph6, Gh 0-1, kh 0-1, TDS 000
      I added 6 blue bolts about 6-8 weeks later, then some red ruby  and red wine a few weeks later and 3 blue steel in March 2018. All went quite well, though there were a few deaths but that may have been me as I am NO expert, I do drip acclimatise though. April 2018 Eggs started appearing (difficult to see on TB) and by the end of that month shrimplets, woohoo!
      Time for the new tank, dennerle 35L scapers which I got in May 2018 which I ran for a month with the zerowater, 2 cheap sponge only filters, heater, light, rock, wood, java fern, soil etc, and one sacrificial fish (don't worry he went in the fish tank afterwards as he survived). Then I transferred shrimps a dozen every other day(ish) etc. At this point I was obviously shutting down the small tank and although I had only bought a dozen shrimps originally, when I started removing stuff it turned out I had about 90 baby/juvenile shrimp in the tank, most were probably only days old (probably wasn't wise to transfer them at that stage really but I had too many anyway and wanted to get the old tank out of the way, as it was on the dining table). I THINK WE CAN SAFELY SAY THAT I HAVE CRACKED IT NOW, WITH THE HELP OF THE ZEROWATER FILTER JUG. So closed down the 15L end of June 2018. Daily now I see about 50 shrimps of half to full size in the new setup but haven't yet had any success with babies (though most of the shrimps may not yet be mature enough as I believe they need to be 6 months+), and with the hot spell (unusual for here when tank got to 30 degrees) and with me fine tuning the parameters, done now thankfully PH5.5-6, Gh 4.5, Kh 0-1, TDS 160 (something incidently I probably wouldn't have had to do if I had added the Gh+ from day 1 with the new tank). I will say that I NEVER had any Ammonia, Nitrate or Nitrite readings in the new tank either, but as with the small starter tank there were a couple of days of bacteria bloom. I expect babies will happen now I have stopped messing with the parameters, but there is always option B, set up the old small tank and use as a breeding tank, or C, buy more shrimps???? With the shock of how many babies there were hiding in the small tank, there could well be loads of babies in the new tank that are hiding anyway. I will give that a rethink if there haven't been any babies by xmas, though I have enough anyway at present. The only other things that may now affect babies (ie different than the smaller tank) is, the jets from the filters are a bit strong and circulate the water in the tank more, and I have rock (actually Geodes) in the tank???
      I change 2L of water each week, mainly so I can squeeze the 2 sponges from the 2 filters and just clean the glass etc. I also use Fulvic acid, beta glucan and am just starting on bacter ae (hoping that may help babies). As with RO water, top up is pure zerowater and water change is zerowater with GH+ added.
      Each zerowater filter does about 100L of my water (about 6-8 months worth) but there is info on the website above that shows how many it will do on different TDS basic water etc. The filters aren't cheap at £20 each (I have bought 4 for £50 so much more reasonable, and they don't have a shelf life anyway. They are of course available readily in USA in places like Walmart as it is an American product. If anyone knows where you can get them in other countries it may be a good idea to add it to this string/topic etc to help others, as mentioned before I THINK you can get them on amazon.com.au for Australia.
      If anyone wants to ask any questions I will do my best to answer, but I am NO EXPERT by any measure.

      Update 27 Sep 2018
      I am daily seeing babies, in small numbers (all colour varieties), but from the top picture you can see there are a vast number of hiding places anyway, so there must be others. I have also seen a couple of shrimps heavy with eggs, grey, so they must be near birth...............
      I will keep this updated if there is anything worth reporting, or there seems to be any problems with using the zerowater filter jug as a substitute for RO water but so far (1 year now) all has been very successful.
      Update 7 Oct 2018
      Probably be the last update - unless all goes wrong etc
      I am seeing lots of babies of varying sizes and patterns now (20 today), so much so that I am going to have to start culling to make room for just the ones I really want to keep, and enough room/food etc for babies! I will try taking one big one out each week when I do maintenance and see how that goes!
      Any questions just ask!
      BIG UPDATE 24 MARCH 2020
      MORRISONS SUPERMARKETS HAVE STARTED SELLING ZEROWATER HERE IN THE UK!

      Exciting news: I just purchased 15 tangerine tiger shrimp from a local breeder, in exchange for some of my abundance of endler fry. I’m starting the drip acclimation now, along with my other two tts males who I’m moving from my larger tank. I’ll add some photos down below once they’re in the tank. Will acclimate another hour and a half probably, and feed the fish a bit extra before they go in for safety. There’s heaps of good hiding places in this tank, and I can’t wait to see the shrimp utilising them (or hopefully not even see them)!
      Will update soon.
      Cheers,

      Hey everyone,
      I was recently (meaning today) given the opportunity to set up a breeding tank for some native inverts (or some harder to breed fish I guess, but I want to go for shrimp) in a fishroom I help out in. I've been trying to decide what native shrimp I want to try breeding, but then I remembered that it's not as simple as exotics. Can I get some input from the 'experts' (@Grubs, @NoGi, @Baccus, @fishmosy, @jayc of course, I know most of you aren't very active anymore, but I would appreciate your help if you see this message) on what native invert you guys think is easiest to breed (for a semi-noob who hasn't kept natives before). I can set it up as brackish I think, we have an archer fish tank there and are setting up a saltwater as well so should have access to those tools and materials.  
      Cheers!

      Hey guys, I’m really wanting to get freshwater crabs, and the only ones I’ve found are A. Lacustris and A. Laevis. I can only put them in a 110 L community tank for now, but may have another option in the future. The tank is stocked with a large school of ember tetras, some rocket killies, some endlers, some tangerine tiger shrimp, and a pair of apistogrammas. Rare aqua advised that A. Lacustris would likely be eaten by the apistos, so the obvious choice would be A. Laevis, because they’re larger... right? But I’m worried that they might predate upon my shrimp, so wanted to hear some advice and opinions from more people with experience keeping these crabs.
      Cheers!

      Really pleased to hear that your yellow shrimp tank is sorted now and you didn't even have to buy any new shrimps to repopulate, bonus! I hope the treatment of the CRS goes well, Ihaen't used any of those reatments so can't advise on those but would go with the info on the thread as that would be updated with the latest information/advice!  Simon

      I suspect the coral and egg shells have caused the GH to increase so I would just take those out and do a 50% slow water change! You will need to do water changes anyway whilst you're trying to re-cycle the tank, the treatments you used may have killed some of the beneficial bacteria, or it could just have been the chicken as you state? If the neocaridina were doing fine without the KH then it would be better to return to that set up, at least until you get it back to normal and stable. The important thing is not to make and big/sudden changes to the water parameters, the CRS will be more delicate than the neocaridina, but all shrimp are fragile creatures! Simon

      Great to hear that you are sorted! I wouldn't have thought Cordoras would eat copepods but as long as it is working stick with it? Simon

      Hi everyone. I've been keeping caridinas and neocaridinas in the same tank for about 2 months now. My neocaridinas were doing very well. Everyone was molting at their own pace and was breeding like crazy. Then I did a stupid thing of leaving raw chicken bits. While my shrimps ate the chicken, 2-3 of them died after that. And now my tank is totally haywire. I've tried doing water changes, tried vacuuming the substrate. My tank parameters are also REALLY REALLY bad.  Nitrates 40 Nitrite 1 Gh >7 Kh 0 PH 6.8 CL 0 CO2 <15 My ammonia is <0.02ppm My tank contents are aragonite sand, black active substrate(in a glass container), coral chips, coral stones, cholla wood, fissiden moss, duckweed, Indian almond leaf, java fern, a money plant, marimo moss ball.  What can I do to make the nitrates and nitrites go away? And is my kh and gh making any sense? I tried adding coral stone, egg shells to increase my kh but it's not working.

      Hi Simon, updates on the planaria and copepods. I tried using planaria trap and really screwed up the tank as I put raw chicken in the trap and when it wasn't trapping any planaria I took out the trap and left the chicken bits inside. I think they decomposed and caused a lot of ammonia as a few of my shrimps died(2-3). Then I used the benibachi planaria zero in the tank (did 2 water changes focusing on cleaning the substrate) and separated my snails and after two doses I don't see any more planarias. I also went to get 3 pygmy corydoras. That really made the copepods dissappear slowly but surely. Thank you so much for your help and advice!
