RO water...

Depends on what your tap water TDS is water changes will help but RO water is the best way to get it down but if you use straight RO then you need to add salty shrimp minerals

Hi Kev,

i reduced my TDS from 330 to 170 by stop adding salt to my water changes which ive always done with fish and even my cherries. my tap TDS is 70 and my tank was 330. with each WC it would drop around 20ppm per 10L n then it raises slightly due to mineral balls or whatever and then reduce again with WC and so on. so its just up to u where u want to stop when u see results.

having the RO and using salty shrimp definitely better if shrimp is the focus but presuming ur tap water TDS is lower than 150ppm u can lower it with each water change... the rate at which it will drop will depend on many factors of course.

what is ur TDS now? where do u want to get it? and what is ur tap TDS?

the rest is all easy to figure out once uve got the pen. u just need to measure the water before and after WC and u'll notice the drop. it took me around 6-7 weeks to drop mine. from there i noticed all my shrimp getting berried and like i told ya yesterday i dont have a single female in my CRS tank that isnt berried :)

hope this helps :)

for those who arent as lucky, my tap water tds is 450ppm. the only real way to do it was to purchase ro unit. havent looked back since, best investment imo.

Hi Micheal,

yeah my WP are nothin special and quite normal:

Ph 6.3

GH 5

KH 1

TDS 160-170

Temp 23.5

i put it down to me having good tap water to work with initially (although now i use RO/Saltyshrimp anyway) and the gradual decline in TDS.. nothing sudden. i add some azoo mineral liquid and it seems a very good product that helps with moulting.. almost every day i have new moults in my tank as i dose this stuff very lightly (probably quarter of the dose rate) every other day. i also have some bee balls and some of that clay rock mineral stuff.. all in all i dont notice big jumps in my TDS its very stable. when i do a 10% WC i do it over 2 days of 5L per day and i do this once a week for now.. i drip that 5L in over maybe 8-10 hrs. very slow but very good. the shrimp would never even realise that new water is being added.. they just have the benefit of not having any toxic build up.

i used to use a spoon of salt per 20L WC. once i got the pen i realised how much TDS this adds (from 70 TDS to 220-240TDS).. not that its bad TDS but for sure the salty shrimp minerals are the way to go. the bad TDS would be unknown solids from tap water like they get in the west or up QLD way i beleive.

last night i was playing around with doses and saw interesting results.. i took 5L RO water and added 2mg salty shrimp the TDS was 95 and GH 5 but ph 6.4.. i then doubled the dose to see what would happen.. basically everything doubled.. (TDS and GH) except fot the PH. i was doing this as ive noticed some cherries lacking color in low TDS tanks so im upping the GH and TDS for them although there final PH will be around 7ish. so for my cherries i'll aim for TDS 200-300 GH 8-10 and PH 7 and ill notice any difference. i will share my findings for those interested.

apart from all this the answer to using additives is yes.. i do have a couple herbal tricks up my sleeve but unfortunately i'll have to leave it at that for now :p

I simply do water change with RO water. If it's still high, you can repeat the wc, just remember not to shock the shrimps.

if it become too low, i add minerals such as shirakura ca+.

The shirakura Ca+ will increase your GH/TDS, but it's does not re-mineralise RO water like Salty Shrimp, Mosura Mineral Plus, Benibachi Mineral Powder etc...., Do you add anything else to your RO ?

I only use Shirakura ca+ to increase the TDS of RO water. The seller told me that this is the one to add good mineral to the shrimp. I use it in all my tanks. The result is good, they all breed now.

Salty shrimp is not exist in here, but i saw this forum use it alot. Like to try if available.

My PRL Asuka, PRL Yuken Line, Aura Blue and Shadow Panda already breed. So seems good. I use ADA amazonia, Ista ph5.5, breeders soil and just try the platinum soil now.

I will check again to see the ingredience of shirakura ca+, thanks for the info.

      Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well.  How do you keep them @Grubs?

      I would get a few if you like them, the odd loss of a baby shrimp wouldn't really be a problem. There are lots of shrimp people that have the dwarf Corys with their shrimps.As you say, it maybe better to wait a bit until you have more shrimps first but the cory doesn't hunt shrimps as food!

      I think that the shrimp in the photo is a female! Great you got the slots sorted so quickly and easily. The good thing with the amano is that they won't breed so you will never get more than you buy. Don't get too many though (may be the 5) as they are bigger and will out compete the cherry shrimps for food. Don't forget that there is postage cost with ProShrimp below £39 (I think that is the figure??) so bear that in mind as if you are close to that and you buy a few more shrimps you will get more shrimps for the same cost by not having to pay postage - f that makes sense? The other option is the tangerine tigers as they won't cross breed with cherry shrimp but you get a different colour - those are out of stock at the moment though! You need to be at home next day to sign for the package. https://www.pro-shrimp.co.uk/tiger-shrimp/563-tangerine-tiger-shrimp.html Simon

      No nothing special. Just get them the right water parameters and that's it. @Grubs might have the perfect water parameter requirements for DAS, so see if he can list them. Otherwise, I used to keep DAS in water that was ph6.8 - 7.0, KH 4, GH6 and TDS of 200-230 and 25DegC.  These shrimp from QLD seem to handle slightly higher temps.
    • Crabclaw
      Yeah tangerine tiger shrimp. I don’t think I would even mind that much if they procreated cuz I NEED MORE SHRIIIIIIMP!!!!  (And the offspring would be cute) Do they require much skill to take care of? (Either)
