Several months ago I noticed that
www.drsfostersmith.com was no longer carrying the freshwater formula for Bio-spira and when I inquired about it they said it was discontinued. So I contacted Marineland who manufactures it and tried to find another source but they gave me some really interesting information. They were not going to make the Freshwater formula anymore. They were revamping the formula so that it did not have to be refrigerated but would work the same way and would not have the decreased shelf life that the old product had. In conjunction with Tetra, they made this product and it is now available for sale at least through the source above. I have ordered a bottle of it and since it can be shipped without refrigeration now the cost of shipping is about half of the previous cost. The total for the order was $28.51 for the shipping and product. I know that is steep but I am thinking that now that the product does not have to be refrigerated perhaps it will start to be carried by more Fish Stores and vendors Locally and be available to more of you without the cost of shipping at all. Since it does not seem to have a "shelf life" problem they may be willing to stock it over the more volatile products and especially if it works as well as the old product did. I know that I have paid upwards of $45.00 for the cost of the refrigerated product when I ordered it by the time I had to pay for the shipping and handling for overnight delivery and special handling by carriers for refrigerated products. This can be shipped like any other product and from the above vendor I did notice that they ship to Canada too.
So I thought I would make this information available to you and if you decide to use it please let us know what you think of it. I will be letting you know what I think of the product when I use it.
