Dear Ken:

About 2 months ago I began using the BZT Aquaculture product as per you instructions. At that time I was having a lot of trouble maintaining clarity on a consistent basis in the 25,000 gallon outdoor aquarium exhibit that I manage here at the Governor Mike Huckabee Delta Rivers Nature Center in Pine Bluff, Arkansas.

The outdoor aquariums are fully exposed to sun the entire length of the day and subsequently their algae load is enormous. I have tried many products to enhance the capability of the inadequate filtration system. Often the water looked much like "pea soup". Adding a new ultra violet light to the system made a significant difference, but the filtration system was not capable of removing the bulk of the particulate matter from the system once the summer algae load commenced. The bag filters were fouled daily with heavy "sludge" and the water, though clearer from the U.V., was still very clouded. Patrons often asked if we were pumping in Arkansas River water because they were unable to see the aquariums clearly.

After the initial treatment with BZT, there was a dramatic clarity the following day. The clarity was not initially consistent until I was able to build the product up in the system over the period of about one month. During that time I added about one cup per week, treating the tanks aggressively. I have been subsequently able to reduce to a maintenance dose of 4 oz BZT, every 2 weeks.

Now, after two months of treatment, I have very clear water, despite facing the hottest and most intense days of summer weather that last year produced terrible visibility due to algae. The particulate matter in the water has been dramatically reduced. The bag filters now stay remarkably clean, even going 2 to three days between changes. The BZT seems to have reduced the algae load on the filtration system significantly and has thereby greatly reduced my workload!

I appreciate all the time and effort you and other staff members gave to help me achieve the water clarity I had been seeking, but not hitherto been able to find!

Sincerely,
