much promise - keep little

In the wake of a new filling my pond with about 20 cbm I used the PhosLock algae stop. The water was just 14 days without algae, seaweed salad dannach be the same as without the use of this drug (pond refilled without this agent was made by me also already repeatedly carried out) showed.
So the use of the agent is a waste of money. There is a lot of promise, but little (actually nothing) held.
Be sure to stay away.
