Hi All,

I compared some greenwater (at last I've got some growing!!), Kent Zoe and Kent ZooPlex.

Kent_Zoe_400x.jpg

Kent Zoe: There seems to be very little (visible) going on here. The bottle says "bio-available vitamins, amino acids and minerals ... spirulina". I guess the small specs are spirulina.

Kent ZooPlex shows a lot more, bigger parts. The bottle says "whole, bio-engineered marine zooplankton ... approximately 800 microns"

Greenwater (Nannochloropsis Oculata) shows a lot more single-cells, some of them congregated around some "other stuff" (a confirmed scientific term).

I think is is something very tiny stuck in the moisture layer on your eyeball and as you move your eye it moves slowly...??? Just my theory... Either that or very tiny aliens that I always thought only I could see but now I know Tremayn can also see it... We're "special"... :biggrin:

Some more pics. At last I've got some rotifers, hatched them from cysts the last 2 days. They're scuttling around like crazy. It's amazing, half a drop of water, loads of little critters scuttling around in it. It's using the 40x magnifier (+10x eyepiece makes it 400 times magnification), and even in that little bit of water, with a cover-glass on top keeping it flat, it's still as if they "dive down" and "come back up", moving in and out of focus as they go nearer or further from the lens. They're supposed to be around 100 micron, so at 400x magnification, they're supposed to be around 4mm - looks about right.

Anyway, now to get them to multiply, which happens amazingly fast - a rotifer will reach maturity in about 8 hours or so, then start producing daughters every few hours. The exponential growth soon leaves you with millions upon millions of little critters. Luckily, my greenwater is up and running, and it seems I'll have greenwater and rotifers at the same time at last ... now to get that clownfish pair to lay eggs again!!

I've read somewhere that it's some kind of membrane that you have early on but that "dissolves" after a while and very small pieces of it remains on your eyeball.

Yup, these "aliens" are called eye floaters, and about 70% of people have them.

Here's an extract from the Mayo Clinic website:

Eye floaters look like black or gray specks, strings or cobwebs that drift about when you move your eyes. Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous humor) inside your eyes becomes more liquid.
When this happens, microscopic fibers within the vitreous humor tend to clump together and can cast tiny shadows on your retina, which you may see as eye floaters.

If you notice a sudden increase in the number of eye floaters, contact an eye specialist immediately — especially if you also see flashes of light or lose your peripheral vision. These can be symptoms of a retinal tear or a retinal detachment, which requires prompt attention
Wikipedia has a rather in-depth article: [ame="http://en.wikipedia.org/wiki/Floater"]Floater - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Vitreous_Floaters.jpg" class="image"><img alt="" src="http://upload.wikimedia.org/wikipedia/commons/thumb/3/37/Vitreous_Floaters.jpg/230px-Vitreous_Floaters.jpg"@@AMEPARAM@@commons/thumb/3/37/Vitreous_Floaters.jpg/230px-Vitreous_Floaters.jpg[/ame]

Very cool photos. Do you have a mountable camera on your microscope or do you use a normal camera?

Thanks all. Boegie, it's a mountable 2MP camera (interesting thing s the camera is more expensive than the microscope). It latches onto the one eyepiece of the microscope. I usually look the the image on screen rather than through the eyepiece(s) actually.
