Recommended Posts

Im so sad, I have lost a lot of the babies that my girls had :-( I have lost at least 2 or more adults every week . Water perams are tds 257, ammonia nitrite and nitrate all 0, ph 6.4-6.6, kh - 1 and gh unable to determine as the water never ever goes orange but yellow and there is no shift visible... the test kits are all brand new ...I am currently just doing dechlorinated tap water top ups ... no lids on tanks ... dead shrimp all intact no missing limbs just dead :-( I have added some seachem reef builder 1g to 500ml divided over 4 tanks and dosed 2x over 5 days so thats the 500 ml over 2 doses divided over the 4 ranks ... I just dont know what to do... some of the old females were old and large so them I put down to age ... but there are so many juvies im just heart broken ; (

Sorry to hear on your losses...never easy :-(

Shrimps are sensitive to their environments... They're many possible reason, but I'll try to dissect and simplify the possibilities, so that you can confirm & act on these suggestion, to hopefully eliminate the issue(s)...

Shrimplets - when shrimplets disappear/die, one of the mist common issue is moulting. The GH has to be 3+, with ther coo ended 4-6 for CRS's. If your GH test kit is new and doesn't chnage colour, I assume you GH is <1... this would definitely be one of the reasons.

Adults - as above, but as the don't moult as frequently as the shrimplets, a low GH will cause issues. Adults, can survive a low GH, BUT will eventually die.

Using dechlorinated tap water is also a potential issues, as copper and other elements can be present....and this can differ from day today. RO and salty shrimp will eliminated a huge portion of the guesising game.

If you add plant fert's, ensure there's no copper content. My advise with shrimps tanks is to keep it simple. A planted tank will eventually cause issues.

Hope this helps....

Wraithy the tank temps have remained steady at 22-24 C. The actual tanks have no ferts at all in them . there is a type of greyish green coarse hair like algae on the filter and on the water outlets from the pumps. the only chemical added has been the dechlorinator and the internal parasite one 1/2 dose a while back for hydra. I just don't get it :( I have a RO thanks to Torface but am scared to use it as I don't know jack about them and shrimp salt etc. I also have to source the salty shrimp and also hook the unit up to the front lawn tap as I have a brand new house that has new taps which I cant use the connection on, I am also yet to source a water storage container. I am really worried about all the loss :(

Don't be afraid of RO and Salty shrimp - I never used these until I came on this forum. You can source the salty shrimp from our forum sponsors and have it in a few days. You also need a TDS or EC pen to mix the salty shrimp correctly. You are a nurse this is easier than drug calculations and IV's. I initially bought distilled water and now have 2 and 4 litre bottles that I store it in for weekly changes. It's really not hard you can do it and it may help you save your shrimp- there's never any guarantees but it cuts out a lot of unkowns:encouragement:

Thanks for that ... does it actually change the GH of the water ... I have tried to test my tap water and also my tanks and they all just come up a pale yellow the bottle says it goes from orange to green . I have never ever seen anything but yellow a pale pale yellow :sour: im just so sad and also have quite a few females that are currently berried and want to guarantee survival of all in the tank. The other question is as always how do I change the GH and also is it safe to change as my water is also GH low ???? damn water perams grrrr

Sorry about your loses. I agree it's possible that your GH is too. Shrimplets are a lot more sensitive and has more moulting periods. Adult shrimps getting ready to moult will be just as sensitive.

From Wat I can see, you were doing fine before and now your having deaths. This means something has change in the tank. It could be a chemical change or a small routine maintinance change. Only you can figure this out as you are the only one who maintained the tank. Also to much calcium will make the shell really thick which sometimes is abit hard for them to moult. Tds should be between 100-180 for good moulting.

That's the thing nothing has changed except I have had to start topping up more due to the warmer weather and since having my chat with you have used dechlorinated tap water. I have not added anything else bar the seachem reef builder in such a small amount that it didn't even affect any of the readings at all. No new shrimp added I did have a hairalgea outbreak but I have not treated it. no chemicals added to treat it nothing I have only thinned it out with my hands after washing my hands as normal. So you see my frustration. using the tap to top up is my only change. the tds has always been mid 200s never below it is actually at its lowest ever today. instead of bringing me joy i seriously feel like crying ... I am just so frustrated. I remember what ppl like alvin have said that was don't change anything and I haven't

Yes, I'd definitely get the RO hooked up.... Can get the fittings/adapters from Bunnings or a plumbing store... I store my RO unit in those 20lt water tubs, purchased from Bunnings, camping stores etc... So they're mobile and easy enough to cart around. Really difficult to pin point the exact cause, once tap water involved, heavily planted ...etc.

How old is the tanks me do you gravel clean ?

How many drops have you been putting in before you decide it is not changing? Maybe you have really hard water and that is why you are not seeing the change??? And as mentioned above, causing thick shells, making it hard for the moults to occur.

has shown me his colours and the colours are extremely clearly cut from a dark orange it goes to green . Mine doesn't even change to orange it is a pale yellowy green. my KH changes on the first drop too.

For shrimp minerals there are 4 options on the BossAquaria shop page.. which one should I chose? the GH/KH +?

May I ask how old/long the tanks have been running for and what soil you are using? From my experience (my experiences only) I notice the tanks do great when they first get going (that is all the WP are good and you add shrimp) they are all healthy and breed great but I noticed once the tank hits the 3-4-5 month stage that is when I start getting unknown deaths. I have 6 tanks and have noticed the same in all tanks (not plumbed together and not all setup at same time). The more mature the tank is the better the shrimp will do (assuming the soil is still buffering etc.). After +6-7 months thats is when I notice they start going good again...Maybe just a coincidence but that is from my experience.

Very coincidental that my tanks are at the 3 month mark as they were established around july. the substrate is ADA Amazonia that had only been used in another shrimp keepers tanks for a month or 2... its buffering well at 6.4-6.6 ph.

That is interesting...I wonder if anyone else has had similar experiences?

just don't get anymore new shrimp until you notice things have calmed down (you will be tempted to replace the lost ones ASAP trust me I know!)...May want to get some live beneficial bacteria to help in the mean time, unless you have a separate mature tank (you can move most prized shrimp to temporarily) and assuming all water params are ideal then there is nothing much you can do but wait it out. Maybe you can chuck in a big bag of quality carbon just in case it is a case of toxins?

      My brother just moved from San Antonio to Florida! It may be more economic to purchase a specific chiller for the shrimp tank, we don't have that problem here though I did cook mine, 33 degrees if I remember, d'oh (faulty heater)! I assume you can get one for a large tank like yours? There are a number of foods that are probably easier and don't go mouldy, like snowflake which is soya bean husks and can be left in the tank for long periods and is therefore better if you are going away for a period. Indian Almond leaves are good for holiday periods as well because they decay very slowly and 'stuff' the shrimp like grow on them. Probably if you are just going away for a few days you may be better not to feed and if there are Indian almond leaves etc in the tank they should have enough to eat. Hopefully you caught the temperature in enough time that you won't loose any more shrimps. Simon

      Yes. I live in Texas. When I'm away freon the house I'll have only one of my AC units running so the cats don't die.  The mold was caused by some food the shrimp didn't eat.  I did a temp check with my other probe  and it was almost 2 degrees higher. I guess I'll leave the fans on when I leave now
    • sdlTBfanUK
      I would think that is possible as that is pretty much the upper limit I think, and of coarse how accurate is the thermometer - I have 4 different methods and all produce different readings so it may have been a bit higher??? Mould isn't usually a problem other than it looks horrid and usually will just disappear after a tank is properly run in and as far as I know not harmful to shrimps. I have had it in most of my tanks at the start, usually on wood or something similar and either removed the item it grows on or just leave it and it gradually disappears within a month (usually less). I hope you manage to get the temperature back to normal and it sounds like you have mastered the TDS. I'm not sure where you are based, is it somewhere hot (I apologise if you have said and I have forgotten)? Simon
    • supermansteve32
      I came home from being away for 2 days and there was another adolescent shrimp dead. I saw the water temp was 83. I know they like to have 70 to 78. Would 83 kill some shrimp?  Also I first started doing water changes again and I had to do a little extra a few days later because there was a little mold I had to siphon out. Not sure if that's the reason either. Also my water TDS stayed between 142-147 this whole time.

      The tanks are only 16L, for it to reach 31c, it isn't hard.
