      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

      But the shrimp will be thinking otherwise. Look at all that yummy brown diatom!

      I am old school like that too. I prefer the classics patterns/colours. And I try very hard to not create further hybrids. I want my CRS to be CRS. My tigers to be tigers. etc...   @kms, all the more to support the site and sign up as a paid member.   @Cesar, what's the deal now with the new forum update? Has the photo size limits been changed, and if so what is the max for regular members?

      Thanks for that, it helps to know that it is probably going to be fine with time. I tried a different substrate this tie so that is all I can put it down too! I will revert to the JBL in future as this hasn't happened with that? I don't use any plant ferttilisers, and as above have never had to with the JBL substrate. The JBL is primarily a plant substrate and the shrimp king is primarily a shrimp one I guess, though they both seem to do the same buffering /softening etc? There will be a bit of a delay with breeding I expect as they don't mature until they are 6 months I believe? Again, thanks for that, it helps to know what someone else thinks and the tank has improved (hard to believe from the photos) going a bit greener and the stringy algae virtually now disappeared. Also a few new leaves on some plants etc. I just checked the water parameters and they are spot on! Simon

      The new update has reduce the photo size to 1.67MB for me, and all the photo taken with my phone is over. My pinto only cost less that GBP 4, as for the Red Wine, its 5 for GBP 10.20, any extra Red Wine will be GBP 2 if more than 5 is purchased.

      New tanks often go through a brown diatom phase and its just a waiting game before the diatoms naturally senesce.  Ride it out. The shrimp will certainly help clean it up and I'd wager that diatom rich biofilm is good nutrition.  You'll have shrimp breeding before you know it.  There is certainly a good complex variety of habitat for them to explore and exploit. Are you using any plant fertilisers yet?
