  • Hi
    I wanted to thank you for your advice in dealing with an algae problem in our pond. We treated it with D-Solv once and it was essentially clear in 2 weeks.

  • Hi,
    I was recommended to purchase Paracid and anti-bacterial fish food from you because my fish were dying. I received the shipment the next day and we have not had one fatality since then! Thank you very much for the advise and the quick service.

    Taina, Uxbridge, Ontario
  • Thank you for the excellent service you gave me today. You suggested some great plants. They are in the pond now and I look forward to seeing them grow.
    A pleasure to meet you and to do business. See you again soon.

  • Hello!

    We received our Crystal Clear ‘Ick’ treatment for our fish. Thanks for sending it out so quickly! We put the first four ounces into the pond yesterday.

    John, Ontario
  • I would like to thank you for the time that you spent today with us. It was so informative and we walked away with so much more knowledge than when we started. We have been asking a lot of questions with other people in your industry but nobody has had the knowledge you two have.
