Appears to be very economical for a smallish water feature. However, although it kept the water crystal clear initially, after three or four days algae developed. I cleaned out the feature and tried using the product at double the suggested concentration but with little difference to how fast the algae developed. The instructions simply suggest replacing half the water every month with product added. However, in my feature, I'd be adding water to a mass of green slime after a month! So, it doesn't appear to work well for me.

Used after flushing the winter debris from my water feature. Product has cleaned the remainder, and lovely clear water is flowing. Great job! Thank you.
