IIRC pool algacide is 1/2 the strength of Physan, so if physan says use 1
tsp/gal you'd use 2 tsp/gal of pool algacide. BUT READ THE LABEL and verify
this before you try it at home.

Same thing: Swimming Pool Algicide, as I recall. You need to calculate a
different dilution, which I definitely do not recall. Very cheap.
