      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

      Well, I am a bit unhappy the baby shrimp survival is bad.  During the first batch of babies back in February, I would often see them grazing along the walls.  Now I really don't see that anymore, probably due to less stuff growing there. I agree with your observations of tanks changing with time, although I have never witnessed BBA myself.  But I think those pictures I see of tanks with "wall of algae" and shrimps grazing on the sponge filter and also old tanks.

      It all sounds similar to what my tanks did at the start, and as they settle algae reduces, BBA disappears, fubgus dusappears etc. I woildn't use chemicals myself or ferts! I see you are using bacter AE which is good. I would (did) use a baby shrimp food every other day (it is usually powder) in addition to what you are already feeding, and if the shrimps are that hungry they rush over I would increase the feeding a bit as well maybe. They only usually dash for food if they are hungry and if there is plenty of biofilm they will sometimes even ignore other food in favour of the biofilm. As they graze it will be unlkely you will see algae grow as they probably eat it as quickly as it grows (like sheep in a field)? I can't say I see algae in my tanks either when there are shrimps in the tank? It is a fairly small tank so the amount of area for film to grow is limited and as the population increases yu will need to increase feeding etc! It is good that you aren't losing any shrimp so I wouldn't change much, as long as you are getting some babies the numbers will soon grow. Everything else looks good to me, so I would just get some baby shrimp food so maybe you will get a better survival rate of the babies and increase adult shrimp feeding a little bit. Simon

      Hello folks, I have a Taiwan Bee tank running for several months now, and generally things are ok.  Most of the shrimp are going around and grazing, especially the juvies which are about 6 months old by now.  However, over the last few months, I suspect the tank has something slightly off where there isn't enough biofilm and algae growth, and overall the "bacterial activity" seems kind of low.  The evidence  for this is: The wad of peacock moss is very branched and growing quickly, so maybe sucking up all the nutrients?  I trimmed it back just 3 weeks ago, but it already grew back. Nitrates are always stuck at zero.  No fertilizers added. DHG, MC, and S. Repens are stunted and yellowing. Driftwood is sparkling clean. Nothing grows on the HMF sponge, and so shrimp don't graze there Stuff (algae) doesn't seem to grow on the walls anymore. IAL don't start breaking down until 3+ months later, despite 10 minute boil.  Shrimp don't graze on it much. Occasionally the adult shrimp will "take the afternoon off", where it seems they get bored of grazing and just stand around.  But then if I add food they quickly come over. Current batch of baby shrimp survival rate seems really low.  Maybe because they are starving? "Dead" things like mulm or dead algae (from a H2O2 treatment) or leaves don't break down and just persist.   At the moment, the tank gets about 10 hrs of light per day of "medium" intensity.  I think if I turn up the lights more, I'll start to get hair algae. Maybe start dosing fertilizer? Maybe add something like Dr Tim's Eco balance?  (Probiotic bacteria)  A few months ago I tried adding Waste Away (waste-removing bacteria) which immediately killed off a few baby shrimp, so I won't do that anymore.  Uhh, but I guess there's still Seachem Pristine (does the same thing)? Anyway, the goal is to have a tank that grows visible algae - the kind that shrimp actually eat.  Sort of like what I see in tanks where they have a "wall of algae" full of shrimps grazing, or where shrimps are grazing on the sponge filter.  Also, where the IAL breaks down quickly and shrimp are actually eating away at it. Feeding schedule for a 5 gal tank with about 15 shrimp: About 2mm worth from a shrimp pellet 3x per week.  about 1 square inch of mulberry or spinach 2x per week.  Dab of Bacter AE, about the size of half a grain rice, 3x per week.

      Have you tested the parameters of the water? There isn't much we can help with without those basic figures? Usually tap water works with neocaridina shrimp but your water may be too hard! If there were DOA then the others may also be sick or weakened so some may die soon after they are put in to the tank. When you get a shrimp deivery you should drip acclimate them over as many hours as possible. Were they delayed in transit do you think which caused the doa? Simon
