The algae blocks worked well in my pond after a few weeks of use. Water clarity improved noticeably and pH stayed stable without needing frequent adjustments. Easy to install and no visible side effects. Would recommend for regular maintenance.

I used the block in a small pond with no live plants. It helped reduce algae growth and kept the water clean. The block dissolves slowly, so it doesn’t release chemicals too quickly. Good value for the results.

The block did reduce visible algae, but I noticed it wasn’t as effective in a heavily shaded area. Works better in open, sunny ponds. Still useful for basic maintenance.
