      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

      Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well.  How do you keep them @Grubs?

      I would get a few if you like them, the odd loss of a baby shrimp wouldn't really be a problem. There are lots of shrimp people that have the dwarf Corys with their shrimps.As you say, it maybe better to wait a bit until you have more shrimps first but the cory doesn't hunt shrimps as food!

      I think that the shrimp in the photo is a female! Great you got the slots sorted so quickly and easily. The good thing with the amano is that they won't breed so you will never get more than you buy. Don't get too many though (may be the 5) as they are bigger and will out compete the cherry shrimps for food. Don't forget that there is postage cost with ProShrimp below £39 (I think that is the figure??) so bear that in mind as if you are close to that and you buy a few more shrimps you will get more shrimps for the same cost by not having to pay postage - f that makes sense? The other option is the tangerine tigers as they won't cross breed with cherry shrimp but you get a different colour - those are out of stock at the moment though! You need to be at home next day to sign for the package. https://www.pro-shrimp.co.uk/tiger-shrimp/563-tangerine-tiger-shrimp.html Simon

      No nothing special. Just get them the right water parameters and that's it. @Grubs might have the perfect water parameter requirements for DAS, so see if he can list them. Otherwise, I used to keep DAS in water that was ph6.8 - 7.0, KH 4, GH6 and TDS of 200-230 and 25DegC.  These shrimp from QLD seem to handle slightly higher temps.

      Yeah tangerine tiger shrimp. I don’t think I would even mind that much if they procreated cuz I NEED MORE SHRIIIIIIMP!!!!  (And the offspring would be cute) Do they require much skill to take care of? (Either)
