      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

      At the time, those babies grown and had babies, those babies also had their babies, during that time, I did not add bacter AE, I never knew what it was, and I was only a beginner, @sdlTBfanUKhelped alot along with @jayc oh, had average 20 babies for each mother shrimp.

      I agree that there probably likely to have more survive with food but if you have 10 already (and there are probably many hiding) that is a good start and it is probably better to get half a dozen each batch (month) than over-run too quickly! You should be fine not using baby food at the moment with the number of babies you have! I had extraordinary survival rates in the original 15L tank which I assume is because they all got some food being such a small tank. Within months of the 8 shrimps breeding I got about 150 babies - it was panic time to get a bigger tank set up! Simon

      I am more of a give a plant a go and it either lives or not, though I don't think anything has died off thus far! I don't know what plants are available to you but they are a personal choice for you to make so just see what there is? I wouldn't use CO2 but if you do decide to use the Flourish excel I would do it slowly starting with half dose etc! I have had algae before with new tanks but it has just cleared up with time on it's own, I guess when the whole system has sorted/balanced itself out! Simon

      Maybe around 10 or so I know that many people claim to have increased baby survival rate by dosing various baby foods or Bacter AE.  What has your survival rate been?

      No plants ‘require’ CO2 so to speak, but it helps boost growth. Flourish excel is basically bottled CO2, so you could do that. Most red plants will just grow a bit greener without CO2. I have some variety of Ludwigia repens, and it stays pretty red, as the leaves reach higher toward the light. But the best thing to do is just try something. Test it out, see what works and what doesn’t, because nobody‘s tanks are the same.
