      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

      Had a quick look in my new invertebrates book and think they are Limnopilos naiganetri! If so it says temperature 24 to 28, Ph 7.5 - 8.5. They should be given driftwood and floating plants. It also says that although they carry eggs, raising the young has not been done in captivity (book produced 2015). This youtube video says she has had breeding though???? https://www.youtube.com/watch?v=aPOIq4AsZCE I had thought about getting some in the past but as she says they are a bit like spiders so that put me off................ Hope everything else is going well still! Simon

      I'm really happy, finally a local shop in Hong Kong had some of these crabs, not to sure which variation of the spider crabs,, but they advertised them as miniature spider crabs (Limnopilos naiyanetri) , I was going to bring them back from Taiwan if I find any, but no need now, got them for about GBP 13.50 for 10 crabs, I will pick up another 30 crabs in the next few day.   The first photo is the crabs in the bag, I won't get home till tmr, the second photo is taken at the shop.

      You can do large water changes, I do it every 6 months to reset the minerals in the water, but you cannot just dump the new water back into the tank. It needs to be fed in slowly. I drip in the new water after adjusting it to match previous parameters.

      Shrimp don't need much of a water change as they are low bioload! I have 30L and only do 2L per week so as with JayC cut back on the water change amount, even .5 litre would be ok! Large water changes tend to trigger moulting so they may be moulting too often? They may drop the eggs if they aren't fertilised and therefore unwanted! Have you seen any that look to be able yet?
