      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

      Here are a couple of vids, https://www.youtube.com/watch?v=g-FhLa3gl5o https://www.youtube.com/watch?v=mfFyDb5o4iA It would be worth trying the salt treatment, or malachite green. I have 'Waterlife fin rot and ulcers' treatment that I got from ProShrimp, that definitely has malachite green in it and may work, though they may sell something 'malachite green' on its own? Here is a link to their treatments, lots, https://www.pro-shrimp.co.uk/search?controller=search&orderby=position&orderway=desc&search_query=treatment&submit_search= Always treat seperately from the main tank, and if you can set up a temporary quarantine tank to house them during the period of treatment, that is better, even a bucket or something would do!

      We havent added anything new for a while. The yellow is definitely not eggs but from what I can read on line that is the parasite. It is only on the underside of the shrimp. Looking on line seems to suggest ellobiopsidae!! Sent from my SM-N960F using Tapatalk

      Sorry to hear you have a problem. It is difficult to make out from the photos but obviously it is difficult to take photos of something so small? Try looking here, there were a coupe of possibilities I noticed having a quick glance through it, vorticello, parasites https://skfaquatics.com/forum/forums/topic/5052-shrimp-diseases-and-diagnosis/ Both the ones I saw say salt treatment so that may be worth a try anyway (not household salt but aquarium salt)! Any idea where they came from, have you added anything new recently? I assume the yellow colour is eggs of the shrimp. Hopefully you can set up a temporary quarantine tank whilst you try the salt treatment and others may give some further advice! Simon

      Hi all. Watching my cherry shrimp today I have noticed several have yellow bits on there under side. Definitely not eggs. I have removed all I can see are infected. From what I can find on line it appears to be a parasite. I can not find any treatment options. Can anyone help. I do a minimum of 10%water change every week with zero water with added gh+/kh+. I clean the gravel every week also. Any advice gratefully recieved.   Sent from my SM-N960F using Tapatalk

      I hope the tank doesn't take too long to make, and everthing arrives in good order! As you say you are planning on Cherry shrimps things should be fairly easy and straight forward with regards the type of substrate and rock and cherry shrimp are quite adaptable! As you say, you will have to wait and see what rock you can get before you can really settle on a design/layout etc. Substrate usually falls into 2 types, inert or soil, whereby the soil reduces/buffers the ph (you don't need the buffering with the cherry shrimp as they prefer higher PH) but looks more natural and is good for plants. We have a new soil substrate which is made by tetra (german I believe, and quite new) that doesn't alter/buffer the PH but I don't know whether that is available to you in Australia, but that would be the best for both cherry shrimp and plants? You can just use gravel or sand with cherry shrimps if you don't want the soil? I assume the tank won't be covered therefore it may suffer from evaporaton and this will need to be TOPPED up with RO (or equivalent) water otherwise there will be a build up of TDS over time? If your rainwater you plan to use has a very low TDS you may be able to gat around this so you won't need to buy RO water etc! You can't really go any further with this aspect though until you have tested your source water! I hope you manage to source some great rocks for the scaping! Simon
