I noticed recently that there are tiny, clear worms in my slider's tank. So I cleaned his tank and then I filled the part that was underwater (the worms reside under water level) with boiling water.
Satisfied that nothing could survive that, I added ice and then added Brogsworth after it was cool enough.
I looked closely and the worms were still there.
What are they and how do I get rid of them? I didn't want to use just any chemical b/c I know you can't use some of those with turtles.
