No?

"Can allelopathy be used to control algae growth in the aquarium?
The answer would be NO! One would have to advocate lowering the water
exchange,
which would be controversial during an algae plague! Only by a very modest
water
exchange programme, would the toxic chemicals be able to build up to a
significant
concentration level required to pose a toxic effect. "
