Review on Birdbath & Fountain Protector 16 oz. – Clear Water Solution, Pack of 1 by Kristina Scott

Disappointing first use, green algae formed in the morning after the next use. Clean, fresh chlorinated water used - followed instructions with 1/2 cap, seller suggested using a full cap, tried cleaning the fountain again, replace the water with fresh every day, less algae, and cleaning is easier than without , but apparently we have dirty birds doing their duty while bathing! It's disappointing that using a full cap instead of a half cap results in fewer uses per bottle.,
