Peroxide dosing and spirulina test

[ndz98]

For the spirulina test (forgive me if that isn't what it is called) to test to see if it's that or cyano, do you just take some out and put it in a cup of peroxide and let it sit over night? What color should it be if it is cyano? If it is spirulina?

If it is cyano, I'd like to start peroxide dosing. I know you're supposed to add a little more each week but I'm not sure what the amounts are. If someone could give me some insight on how to do that I'd appreciate it!

My total water volume is about 34 gallons.

Also I am moving the tank next week so would it be a better idea to start dosing after I get it moved or does it not matter?

A reason to wait until the move is because changing or cleaning the sandbed can stop both of them without any ID or treatment, sandbed work alone can do the job along with making sure the lighting is less white and more blue.

The move is a chance to access and detail clean the live rock areas it may be growing on, and don't fret if after cleaning you have a couple touch up spots due to the wait. These invaders are best siphoned out when you first spot them vs letting a self sustaining mass build up.

The only reason to use chemi clean or peroxide as treatment in either case is because the keeper wants to avoid sandbed work, or any work at all other than water dosing. Once you move you can easily blast rinse the sandbed in tap water till it's clean and reuse after a saltwater rinse, what I do, or you can simply replace it or forego it altogether + clean rock and bluer lighting and you'll be good till the sandbed fills up with waste again. These organisms travel the globe and exchange between environs on their own and it's nearly impossible not to seed our tanks with them as we stock and trade frags and fish. The winds can even bring cyano to our tanks at times depending on conditions
