    I was advised to get a Brunnel sp22, it came with another box that had various bits in including a book with pictures of what you are looking for.


    As for scraping, perhaps getting someone who knows what they are doing to show you would be a good idea.. I've scraped many fish now and am still not 100% confident.

    How to scrape and what microscope?

    Hi
    A microscope needs to have upto or over x400 so if you have x10 eyepiece then your objective lens should be. X40 therefore x10 x x40 = 400.
    You will need to learn, how to scrape! Start by looking @ what is on your pond sides? I personally use old plastic club/bank type cards, (so they are not sharp) scrape then transfer to a slide ensure some (a drop) of pond water over the deposit. Then under the microscope stage start with a Low mag ie x100 or x200, & begin to search all of your slides deposit?
    The next stage is to identify what you are looking at? Ostensibly the parasites will be moving, spinning, slithering etc..... when you find something, start looking at changing up your magnification, to be 100% sure that what you see, can be identified? This is the bit you need to get some knowledge & experience to be absolutely sure!
    Only then you can treat your pond effectively & safely.
    Hope this helps.

    When you do a scrape make sure you go with the scales not against them so head to tail direction not tail to head OK.

    Be aware that the fish will probably try to flip or jump so make sure there is nothing around you that the fish can land on and damage itself.

    Hi

    You will see all the critters that we usually come across at x100 but at this magnification Costia will be pretty small and with a lower end scope you can miss it. x200 or x400 will cover Costia comfortably.

    Apex Practitioner is a good entry scope.
