Doing my head in - High nitrates

Recommended Posts

fishmosy

Highly possible. It seems weird though that a substrate would leach nitrate instead of ammonia. Maybe there is ammonia in the substrate but it is being converted to nitrate by your filter. I wonder how long it could continue to leach nitrate/ammonia?

@fishmosy that is the question. I have also added an airstone to the tank too fyi.

Excellent.

What are you using?

 

It could be the ADA soil.

Only way to test it is to take a cup of it out and add RO water and test each day.

some nitrate remover pad i was suggested to use by the aquarium, they have used it successfully before.

I won't worry about taking the soil out to test my number 1 priority is getting nitrates down. I'll report back maybe tonight.

Okie dokie. Well if you need to get more ... Macropore is the recommendation.

whats the main differences between Macropore and purigen?

 

i use purigen 24/7 just keep recharging it, it is the same thing kinda? just different brands?, i saw Macropore can be recharged with salt water, where pruigen is bleach

The only difference is price as far as I know. Macropore is cheaper.

Macropore can be recharged with salt water, but bleach is more effective.

oh ok so guessing purigen can be recharged with salt water too then?

I think so.

When used in a Salt Water Marine tank - use bleach.

When used in a Freshwater tank - you can use bleach or strong saltwater. But bleach is more effective.

rather than finding the cause, i would suggest reset the tank

the casualities would be more expensive than building new tank

 

and i don't understand why u got failed molting when the gh already 4

4 should be a good parameter

OK little update. Last night I did a 25% water change and came back with these figures this morning:-

6.2

0 ammonia

0 nitrite

20-40 nitrates

1 kh

6 gh

180 tds

 

From my eye the nitrate test colour has come down a bit, but obviously not enough for my liking. My next plan is to do another 25% water change tomorrow and then retest parameters about 6 hours later.

 

I will restest nitrates tonight again and see if there has been any movement. There has been no deaths since, but interestingly enough the YCS in the tank are not moulting and it has been a long time since i have seen them moult, especially the berried females.

 

@salvanost I have thought about a reset, but with a baby due any day now I don't really have the time to start again and devote too much time to it.

Larry mate!

Stop mucking around with nitrate pads and water changes. They are not working fast enough.

Get the Macropore asap.

Here is a reference ... http://shrimpkeepersforum.com/forum/topic/4431-nitrate-removal-product/#comment-68820

Dean himself used in on his tanks that measured 80 and after 3-4 days it was less than 5ppm.

Just saying ... :happy:

I've been having exactly the same problem with my tank for months now.  Thing is, there aren't that many shrimp deaths and there are berried females/successful juvies/moults.  If anything I worry that I don't feed the shrimp often enough.  I'm wondering if my test kit is wrong (I don't think it is as I've tested my other tank with it fine) or if I've managed to breed a super-hardy Taitibee colony. 

I'm going to add some more iron and potassium to see if that works, but (as you'd expect for a tank with high nitrates) my plants are looking super awesome and I'm going to need to do a big moss trim shortly.

My tank has been set up for nearly 3 years now, and it does use ADA soil.  I try to do a 15% water change every week, but it's a 440L tank so refilling is a massive chore and some weeks it gets missed.  The nitrates never used to be a problem, so I'm not sure if it's something that could have changed in the soil over time, or whether another product I've started adding has tipped the balance. (From memory, it'd be beta-glucans, biozyme, and occasionally blue exit - also used to use brighty K and green brighty step 3 but obviously haven't used those for a while).  I upped the lighting period a few weeks ago but that doesn't appear to have made any difference at all to the nitrate levels.

Lost another TB last night it had discolouration, never seen it before. I took a photo but for some reason iPhone didn't save it to the album...the discolouration was like an orange on a black tb.

That means the shrimp has died for a while.

Dark coloured shrimp will change colour to orange after death as it looses it's pigmentation. 

 

Have you picked up some purigen or macropore yet?

I'm now also trying to source some macropore or purigen this weekend, but I'm having trouble finding any.  All the online stores mentioned appear to be sold out, and none of my local (Melbourne) aquarium stores carry it.  One did recommend continuum powercleanse XL instead, has anyone trialed this with shrimp and compared the performance to macropore?

Ordered from the tech den, already posted hopefully get it on Monday.

just went to an aquarium and tested the water all the same readings as I get, except nitrates between 10-20.

the shrimp would have been dead for a max 14 hours as I checked before I went to bed last night and all good.

10-20 isnt to bad, its getting better from what it was, couple more daily water changes and it might be ok, just do daily tests to keep an eye on it

I swear I checked their site earlier and it was all sold out.  Maybe I was hallucinating?!

I found some in a local hydroponic store, so tested the nitrate one more time and then added it in (tonight I've just hung it in front of my powerhead, tomorrow I'll put it in the filter).  Looking forward to seeing what the results are.

      Hi
      I have an issue with my old tank, which is around 3 years right now and the issue is NO3.
      Currently I am forced to do 25-30% water changes twice a week, and this is just enough to keep the NO3 below 10 (which is still way to high!). I have no idea what is causing the NO3 to raise so quickly as there is just around 50 shrimp and nothing more.
      The tank is 30L (8 gal), inert substrate, heavily planted, I add no fertilizers.
      Plants are duckweed, anubias, cryptocoryne, and eleocharis parvula carpet.
      Two HOB filters - one is sponge, the other one is small sponge + peat + JBL nitratex + seachem matrix (I added two weeks ago, as this thing is supposed to bring down nitrates, but so far no results).
      For water changes I use salty shrimp GH +, Azoo Triple Black Water, Azoo Mineral Plus(every second week) and Azoo Ph Down, to adjust the pH of the water that goes into the tank with what's already there.
      As for bacteria I add seachem pristine, and seachem stability once a week around 2ml of each.
      Feeding is once per 2-3 days, small amounts that gets eaten in a few hours.
      So I had that issue already around 5 months back and what I did is bought the JBL bionitratex and added duckweed, and it did solved the problem but to get a good result I had to use two bags of the JBL product for a single tank (the product comes with 4 bags total). Now this thing is quiet expensive imo for the time it lasts, so I would like to ask for any other options to keep the NO3 in check, as the plants are clearly not able to handle that.
      From my observations - there is a substantial amount of muck in the substrate, but since the tank is heavily planted I cannot vacuum it.
      If needed I can provide some pictures of the tank.
      Your help greatly appreciated !

      Hey SKF,
      I've recently started adding 2ppm of nitrates to my weekly/fortnightly waterchanges as my tank constantly had zero nitrates and my plants were looking hungry. The product I use is cal aqua labs green.
      I'd like to know what people's experiences or opinions are on whether small amounts of fertiliser can be added to shrimp tanks WITHOUT dripping it in slowly (as in a typical waterchange which is what I'm currently doing)
      In other words; if I directly dose the 1 or 2 ppm worth of nitrates to my aquarium without slowly dripping it into the tank would it have any negative impact on the health and/or breeding of crystal or tiger shrimps?
      love n peace
      will

      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.

      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
