Hello everyone and I have decided to start a product review on some products from Prodibio, these being start up and bioClean. I was too eager and impatient to wait for my tank to do a fishless cycle and like many out there I looked for an easy and quick method to cycle my tank and found these products. Now I know what I am doing here is not the ideal way to start up your tank but for anyone that is not willing to wait or needs to start up a tank quickly in an emergency I hope to be able to give you either a new method you can try or a method you can completely avoid if it turns out Pridibio does not work as suggested. I have heard some people use a more know product called Tetra safe start. A petsmart employee who could have just sold me the product actually told me they didn't advise it and that it was only about a 50/50 chance the safe start actually worked correctly. So I went home did some research and found prodibio. I did not find many review but the few I found did say it worked great for them so here I am trying this product for myself and will pass on the results to you fine people for you to make up your own mind. With hopes this helps someone that wants to use this product.
