Aquaguard (gel type): Examples of introduction and users’ voices
- We found that the carps living in our pond looked more vivid than before, and on clear days, with fish shadows on the pond bottom.
- We had thought that there had been a small number of fish, but as the clarity increased, we were surprised to find a lot of fish living.
- We had given up fighting with algae growing in our pond, but are surprised that we were able to remove algae so easily, with minimal effort.
- Although none of the other algicides used had had long-lasting effects, Aquaguard (gel type) was effective over a prolonged period of time, making us feel a difference.
