Shrimp water changing method discussion

Recommended Posts

Do you know whats in the mineral mix? If plants are using it, some would have to be fertiliser?

Do you run high densities/numbers of shrimp? If you do, it may explain why there is no build up, as i bet the shrimp would be using it up. It has a lot of similarities with how marine keepers have to supplement their water to keep up with the growth of corals, even in massive aquaria.

RO water or clean rain water is best to use with the saltyshrimp bee shrimp mineral GH+ :)

what do you want the water for then? most aquarium shops that sell marine fish have RO water for sale.

He means you need salty shrimp minerals ;)

Im serious you do :stupid:

you can not use RO/rain water for shrimp with out adding minerals back to the water. the shrimp will die.

if your using tap water just be sure to use a De-chlorination product first.

so does tap water still contain the minerals?

i shall get some saltyshrimp latter down the track when i get more serious:D

Yea, tap contains minerals, RO, Distilled and Rainwwater are stripped of these minerals hence people add back minerals through tap water or a mineral supplement like Saltyshrimp. Saltyshrimp is actually pretty cheap at $35 for about 1500L of water ;)

Nice Dean, certainly makes alot of sense about not doing water changes, and top ups with minerals, now i have a better idea of your system. Probably more prone to increasing tds in a smaller tank.

This interests me alot as I'm doing my PhD on sea urchin aquaculture; the way in which sea urchins strip seawater of calcium carbonate, particularly in the high densities suitable for aquaculture, shares some similarilities with how shrmp in our tanks use minerals from the water to grow their skeleton.

i would have to agree about smaller tanks and the need for small water changes sometimes. but i dont have any so can not comment with 100% certainty.my smallest tank is a 4x2x2 and it has not had a water change for about a year now. i just do top ups but it also doesn't have the mineral additives ads its a tap water tank. i use rain water for 4 top ups and tap for 1 and do this always. the PhD sound like you would have a much better understanding of this than most. i am only speaking from experience with my tanks/system and as we all know with shrimp keeping, what works for one person doesn't always work for another.

Your smallest tank is twice the size of my Big tank!!

Dayum, i need a 6x2 lol

im adding half spring water and half tap water to add the minerals back into the system, sound good?

I use ro water for top ups (evaporation ) and if i want to lower my tds i use ro and take a bit of tankwater out .water change rare but if i do i remineralize the water with mosura mineral plus to the same tds or lower by 10-20 points

As i top up i allways do this slowly with airline and clamp ,to drip in slowly .I just got some bee shrimp mineral from Dean and will give it a go

I always say keeping aquariums is more art than science. I bet even if i took over looking after someone elses tank/system, doing the same things they do, that i wouldn't be anywhere near as successful as they are. All the little tweaks that one can do knowing their own tank/system makes a huge difference.

Oh and if you are interested in some of the work i do with sea urchins, my first paper can be found here

      It can be done, but I wouldn't say it is without issues.  Without a buffering substrate the water conditions can be impacted by something very quickly. The pH will fall or rise very quickly, too quickly for Caridinas. So ... if you can be very careful with monitoring water parameters and keeping to a strict routine in maintaining the same-ish parameters week after week, than go for it.

      Yes I do...

      Great to hear everything is going nicely and you feel ready to start transferring more to the new tank. You were always going to have the PH difference as you are using soil but my cherry shrimp I have in both tanks thrive ok, it just means that you should drip acclimate them probably most of the day to be on the safe side and it is easy enough with the dripper to just leave it going all day. I am not advocating doing this, but as I was putting the cull shrimps into the new betta tank which had a low PH due to new substrate I just dumped them straight in and they were fine and I didn't see a dead one ever (I saw 10 the other day which is about the number I DUMPED in there) - they are much hardier/adaptable than the bee shrimps. I would do as you want/propose and try 10 for the first transfer! I really don't think you will have a problem with the PH difference but would do a long acclimatising to be safe. I have the same floating weed and mine grows really quickly but it is much easier to keep that under control than duckweed as when you get too many big ones you just remove a few. Incidentally when I do my weekly maintenance I trim off the longer bits of root to about 2 inches and it doesn't seem to harm them! You should probably keep a close eye on the tanks this week as we are supposed to be over 30 degrees most of the week. The smaller tank will be the one most at risk of excessive heat? I wish my reset shrimp tank was as lush and green as your new one - good job! I have added 17 shrimps so far and saw 8 yesterday? Simon

      Right so i've left the tanks and inhabitants for well this long simply because i dont want things to die off if i can help it and people have said leave it a month after establishing a tank before adding shrimp. Other than doing normal maintenance and transferring the 2 liters of old water from the small tank to the large each time and the large tank then getting an extra 2 liters of mineralised new water. Friday i sorted out all the tank decor in both tanks and adjusted the tank TDS to within 5TDS of each other. mainly because i needed to cull the flaoting plants which in the large tank the frogbit has taken over and in the small tank the water lettuce had almost taken over. the Duckweed has all but died out in both tanks not that i have done anything to aid it. my tanks now look like the attached. i then took readings they are as follows:-

      Small tank
      TDS - 232
      Temp - 23C
      PH - 7
      NH4 - Unreadable
      N03 - 1PPM
      N02 - 0.05PPM
      P04 - 2PPM
      dKH - 2
      dGH - 6

      Large Tank
      TDS - 237
      Temp - 24C
      PH - 5.5
      NH4 - Unreadable
      N03 - Unreadable
      N02 - Unreadable
      P04 - 1PPM
      dKH - 1
      dGH - 5

      So the Phosphate is up but thats because i was massively invasive in the tanks and churned up the fertaliser i have in the tank substrate. The PH is also what i would consider to be completely off

      also as a side note its worth mentioning that stressing plays out seems to stimulate them to give birth, i now have an extra at least 3 fry appear in the tank just after the works when the mothers had seemed to have stopped giving birth.

      i also got a new fish the in other breed of platy because the fish keeper at my LFS told me they could interbreed and it might make what im doing with the fish go faster, i got him today and named him Rodney and am about to add him to the Large Tank with Tyrone  before taking Tyrone out and putting more females in the tank with Rodney to let nature take its course. the Fish keeper did tell me to drip acclimate him however as the PH shock may be too much so that's what I'm currently doing and he's on his 2nd dip.

      that does make me wonder however can i now add shrimp to the tank or is the PH going to be a massive problem. i estimate i have between 60 and 100 shrimp in the small tank and want to transfer over say 10?
    • sdlTBfanUK
      Thanks for replying. I know what you mean about breeding, I started off with about 10 and was soon (couple of months) over 100, and  I am sure that would have kept going up if the tank could  have supported more??? I don't see any reason that it wouldn't work with bee shrimps if it is working so well for your cherry shrimp. Obviously the parameters are different but if you are managing to keep the cherry tanks stable I don't see why the bee would be any different, although they are a lot harder to keep! Worth a try though unless someone says otherwise? I shall certainly follow this with some interest. Simon
