Love it when spammers get backed into a corner. They get all hissy like a cat caught stealing the Sunday roast :D I own an Apex badged Chinascope model that is still being sold under various brands in the £400-500 bracket. That had a QC sticker on it, the mains earth wire wasn't even connected. It's...

I needed coffee just to focus on the web page Looks like interesting, but like Hans I'm struggling to see the difference from a gradient NDF (or one laser printed on acetate).

Definitely not normal, and if that passed QC it says a lot about the manufacturer..

Excellent image and video Saul, love the work you've done on your setup, impressive.

Nice experimental stain work Bob. Thanks for sharing.

Nice video SWmicro. Copepods can be frustrating to chase

To me it looks like a chlamydospore sack, common to some species of fungal mycelia.

Well done, love the restaurant music

Well done. Really like the firsts one, excellent contrast.

Nice catch, well done.

Great work janvangastel, very nice to see a live sample, good illumination too.

I 3D printed a holder for 10 slides + covers that fits into a small 850ml 35w ultrasonic cleaner. One 8min run in dilute detergent (biological washer liquid), rinse under warm tap, spray rinse with distilled water then stand to dry. Best method I've found thus far that doesn't involve solvents etc. ...

Unfortunate but very interesting to watch. Nice catch Plasmid.

Fascinating. Nice work Manfred.

Nice work Louise, keep at it. The filaments with the granules look like Beggiatoa, a filamentous proteobacteria. The granule density varies somewhat and is likely to be sulphur. They use inorganic elements to synthesise carbohydrates, and sulphur is plentiful in semi stagnant ponds. Their rotation c...

Same method for me as my camera lenses. Foam buds with isopropanol, repeated with distilled water, dried with a makeshift blower (a large hand-pumped plant sprayer). Trick is not to over-wet, anything with fibres is a no for me.

One minute you're just swimming around minding your own business and suddenly you're sucked in by a giant eating machine! Great video. Can I ask what camera you use? Louise This was filmed at 30fps with a Canon 550d through an Olympus NFK 3.3x photoeyepiece Louise. I also use a Canon M50 occasional...

Thanks Hans. Yes chasing rotifers around is like herding cats

More scouring of books and online has yielded nothing. Chalking this one down as "Fungal?.. Weird, but move along"

Lovely images adomacro, you obviously put a lot of time and effort into your work.

I recently ran into this same problem. I bought a second Vickers M17 for the 1.25na achro' oil condenser and a second objective changer. The condenser is great but would not provide even full-field illumination for objectives below 6.3x and required swapping to to the original fip-top condenser for ...

Not sure, definitely some bacteria present. Detritus and brownian motion?

A new rotifer found in the microbe aquarium. Powerful feeding currents. In the latter half of the video you can see the dorsal antenna being used to sense nearby dangers.

Microscope: Vickers M17 trinocular
Objectives used:
Zeiss Jena 6.3x Apo
Zeiss neofluar 16x
Zeiss Jena 25x Apo

Seems a bit too uniform and in one plane for it to be fungal, can't rule it out though.

Not sure if this is a worm or nematode (other?), but unable to find anything similar on the web. Lives life at full throttle, observed for some time but wouldn't stay still for a decent shot. Odd behaviour, freed itself from this clump of detritus only to get entangled in another, and another, and s...

Shotcut for me also. Nice work Hans, hopefully you can cure the banding issue.

How are they eaten? Where is the "mouth?"

Hydra are essentially a hollow tube (blind gut), the feeding entrance is in the middle of the tentacle cluster. They can engulf large prey in short order. Here is a good video (not mine) of one in action: https://youtu.be/SS_HYY97ehw

Give it a while, thingiverse is slow to display uploaded designs these days

Scraper for collecting algae samples from flat sided aquariums and culture vessels. Useful for collecting encrusted flora/fauna for study. Slide the scraper vertically up the tank side with firm pressure (scoop section downmost), scrapings collect in scoop and can be rinsed out for examination. Made...
