      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

      Hi there Simon Im terribly sorry for this very late reply but yeah i have bought my molly 2 friends for her to be distracted with. The natives are surely getting better cause im starting to notice that some of them are developing these white stripes on their back. But ive had a problem because ive had few to no juvies in the whole time i caught them. I dont know if these kind of shrimp need brackish water or they may simply just be eaten by the molly. Oh and by the way i have this really really annoying planaria infestation in the cull tank which could be an explanation to the lack of juvies but ive no comprehensive evidence of their absence.

      You're doing fine so carry on as you are until you feel the cycle is done. My normal schedule is 10%water change every week however I don't think you need to do any while the cycle is going on until/unless the nitrates or ammonia get too high, or the PH gets too low. The lower the Ph the slower the bacteria reproduce! As you only have 2 shrimps they won't be messing the water enough anyway at this stage, I hope they are still doing well? Can you take a lower resolution photo, or reduce the photo size on a computer? If you want to email it to me I can reduce it for you lavissimon@gmail.com - I had to do it often in the past.. Simon

      Ok I will continue to add fluval cycle every other day starting today. I have a piece of driftwood I could add which will lower ph too. Should I only water change once a week? Also, I have 3 java ferns, some small almond leaves, and driftwood. I can’t upload a picture due to size.

      Do you have plants in the tank? And sorry for asking multiple times, but can you send a photo of the tank through so we can see the setup?

      Yes, just right.   That's good news. It looks like there is some bacteria in the tank and it's processing the ammonia. Nitrates are building up however, but that can be reduced with water changes. Continue using the Fluval Cycle at every water change, ie. weekly. Just keep working on reducing the pH slowly.
