    rather young, but seem to be in good condition.
    I ve posted photos in the threat Phoenicurus?

    Hallo Pavel,
    yes, they have their own test drops calibrated for their photometer.
    But you can calibrate also other tests from other brands, for yourself of with help of the Halanek/Gabriel. If you have a known brand of test kits, I suppose you can tell them to calibrate the photometer with S.. or T .. or so.
    You can also sent them your tests and let them calibrate with the photometer they will send you.
    Calibrating with other test is a special service you can find in the price list.

    Alas they don’t have an english version of the website.
    I order the test kits from that company because its easier and even not more expansive than sera and tetra or so…

    Hello!
    Now I just had time to measure all my peat water – water prepared for water change by osmosis and peat and my three blackwater tanks. One of them half a year old, one of them about three months old, one for about 9 months old.

    Nowhere I could find ammonia. I measured with drop test and photometer of Halanek and Gabriel in Austria.

    I use black peat granules from Fimö Aquaristik.

    Ijl and me have found out : larvae of Eristalis tenax!
    🙂

    in reply to: Living food for Paros #7175

    :unsure: I find now a new species in my balcony buckets – didn’t find any thing in the www, forgot to make a foto:
    But it’s easy to describe: as large as black mosqiuito larves or bigger, when grown,
    It has just a zeppelin shaped body, and a thin, thready tail as long as the body. … In the sieve it looked first like a worm, than I saw the tail. :blink:

    Thank you!
    I have Hobby and JBL. As I wrote, they have 0,3mm, 0,18 mm and 0,15mm.
    0,3mm is too big, and 0,18 mm too small to let
    Naupliae through, except a few very small naupliae,
    these really without eggs .
    Now I can get a 0,2 mm, I’ll order this for my next try.

    Hello again!
    I´m still making my investigations … 😉
    The “light method” is really good, but I´ve still now not found a bigger plastic bowl and the stuff to make the separation, but I´m looking for, to follow Deepin peats way to get a bigger amount of naupliae.

    Till now I have now three of those black ones on my photo.

    But I still didn´t give up the sieve method.
    So far as I see now, I will need a sieve plus minus 0,2 mm .
    The normal naupliae sieves of the hobby market are available in 1,0 mm, 0,6mm, 0,5mm, 0,3mm,0,18mm and 0,15 mm.

    Relevant for naupliae are 0,18 and perhaps 0,15 (here you can get the very small ones).
    In 0,18 you still find napliae and eggs if they come through 0,3 (directly the same, but it was the try to get them separated with that 0,3 😉 ). Therefore I guess the right size of the sieve must be between 0,19 and 0,23 perhaps ..

    Now I´m looking for the sieve with the ideal size 😉
    Normal european industrial tea sieves are not smaller sized than 0,5mm, thats already very very rare and fine …

    I´ve found a website of an aquarist who sold last year naupliae sieves sized 0,2 mm, perhaps he will answer me.

    Thank you!
    Do you cover the bowl also?

    in reply to: Living food for Paros #7166

    Hallo! Fine article!
    I will try the method with a bigger bowl.
    Seems to me a similar method like this:

    I have two of them. But as I said, it’s not so much nauplia you get this way because you can’t put in so much eggs as in the bottles …

    My tablet makes always jokes if I use it for the forum, this time it hasn’t sent my text in the orbit, but turn my foto around 😉 hope you can see it …

    in reply to: Living food for Paros #7163

    Thanks for your answers!
    And I´m looking forward to Deapin peats text!

    Exept the tea sieve I am practicing all your methods.
    The sieve till now not because I´ve read that there would be no chance because the naupliae would be same size as the eggs. But I will try tomorrow with my new naupliae breed!

    Of course I use Sanders (its a fresh new tin), the blue premium tin. Better ones I didn’t find to order.
    I store it frozen, with a very very small opening to fill 10 small bottles, I closed the opening again, the small bottles are also frozen and I take just the amount which I need for breeding.
    I find that I get just about 80% naupliae, never 100%.

    The naupliae seem to be best to separate after 24 hours. Than they are so strong moving to the narrow bottom of the bottle. I put a black plastic bag for dogs excreta over the bottle, light the bottom end with a torch, and there seems not to be much of room for eggs. Its about 2 – 3 cm high mainly just naupliae.

    But there are still left I guess 50% naupliae and 50% eggs.
    The next hours or the next day the left naupliae seem no more moving so strong, they stay mostly swimming between the unhatched eggs ….and the unhatched eggs stay unhatched …

    Hallo!
    Now I have another question ( 😉 I seem always to see problems no one seems to have 😉 ):

    You can find enough different methods how to breed brine shrimps so that we don’t need to discuss them all here.
    But I see following problem:
    There is the possibility to breed them in breeding bowls? shells? I don’t know the right word, that gives only a small amount of brine shrimps, but you have no eggs in the little sieve where the brine shrimps swim to the light. I hope you understand what I mean …

    And the method to get much more brine shrimps is the bottle method with air pump.
    Provided you use the best quality of eggs – nevertheless you will never get just shrimps, without eggs …
    Just the open eggs swim at the top of the bottle if you switch out the air pump …

    I controlled it with a magnifying glass. I tried different methods. I tried special bottles from the aquaristic industry.
    It seems to me, that no one really controlles this mixture, one is happy to have many brine shrimps in the sieve to feed the fish…..

    Perhaps our Paros will just eat the swimming brine shrimps and not the eggs???

    But it is always a risk, specially with young, small fish, they can get intestinal obstruction. In this way I once lost a whole group of young Oryzias woworae … (but these are fish who eat industrial food)

    Has someone ideas concerning this subject? 😉

    in reply to: bintan/phoenicurus? #7158

    Here are two of my three!
    One male and two female. They are still shy and rather young.
    But now is the fifth day and they beginn to learn that rumor in front of the tank means food … 😉

    Still I have the tank even more darker than normal so the photos could still be improved. ….

    in reply to: my new linkei :-) #7155

    Hallo!
    At the moment seems that the two male court one female … Will this be a problem?

    They had very often now fine black mosquito larves 😉
