Help ID Dino - microscope pictures

[Tuffloud1]

This is the best I could do with the microscope I have. Anyone know what kind it is?

Nice microscope! But, you have way to much jammed into the view for any good identification.

Attempt some new pics where you are focusing on the outskirts of the grouping so that individual cells can be observed without all of them bunching on top of themselves. This will help greatly...

Are these better? This is the goo type that is on my acros killing them. Can you tell what type it is?

Is it advisable to blow my coolia plagued sand with a turkey baster to get them picked up by my UV sterilizer?

I’ve been running a 90 watt UV for the last week and a half. The first few days I did the turkey baster technique and then discontinued because they just appear back after the lights come on the next day.

The UV doesn’t appear to be doing anything. Running it at 600 gph on a 300 gallon system.
