Re: [APD] RE: algae indicators -- or - Knowing what it is isn'tvsknow what it is

All I'm saying is that lack of other explanations doesn't
make alleopathy the correct one. 

Has anyone found any alleopathic chems in correlatin with
the purported effects in aqauria?

As for water changes, you can change as often as you want
and dose the chems back and the plants flourish and the
algae doesn't.
