In my opinion Bacta-Clean wins the best for your money award. I brought Pro Flush to the forum when I discovered it on the web. I already put some in my pond. Someone else, perhaps Ric, told us about Bacta-clean. In looking for a factual way to compare products I figured that if one standardizes on the number of bacteria desired per gallon of pond water one could compare any product that quotes a bacteria count. For other products there's really no way to compare. If you pick a bacteria count based on recommended dosage (I used the dosage recommended by Pro Flush which is one packet per 1500 gallons). This results in a certain number of bacteria per gallon. If you compare the amount of Bacta-clean HC required to get that same concentration you will find the Bacta-clean can reach that concentation at 1/6th the cost as Pro Flush which up until now was the cheapest I've found for a given amount of bacteria. The question still remains as to exactly how much is required to do the job and the fact that a lot of products don't quote bacteria count so they are unknowns. It appears several of us have used various products already so we'll see what the evidence suggests in a few months. I look forward to more reports.
