Dinoflagellates: Identification and Tips

The basics of what I am doing now is H2O2 dosing with 3% food grade Hydrogen Peroxide.  I am going to start dosing 1 mL per 10 gallons, try that for several days, and double it if it is ineffective.  I just started dosing yesterday, and so far, there has been no change.  Here is the cheap microscope I bought on Amazon, and also the Hydrogen Peroxide I bought online as well.
