А... понял....Т.е. надо ставить Один, а лучше два по 85 ВТ. Без гарантий, судя по вашим ветками на эту тему.

UV sterilizers will eradicate parasites, bacteria, viruses, fungus and algae spores. There is some misinformation as to whether UV sterilizers can kill parasites such as Cryptocaryon Irritans (marine white spot) or Amyloodinium Ocellateum (marine velvet). Parasites occur in three stages. The reproductive stage, the free swimming stage and the parasitic stage where it is attached to fish and seen as a white cyst. Properly sized UV sterilizers are effective against parasites in the free swimming stage.
The UV sterilizer size and flow rate are based on the target organism and the size of your aquarium.
Example:
Target Organism = Cryptocaryon Irritans (marine white spot)
System Volume = 100 Gallons
Calculate the flow rate required to pass the entire system volume through the sterilizer twice a day.
Fo = flow rate
9.2 = purity coefficient @99.99%
G = system volume in gallons
T = time in hours
Fo = (9.2 * G) / T => (9.2 * 100 Gallons) / 12 Hours = 76.7 GPH
Next find the zap dosage required to kill the target organism.
Cryptocaryon Irritans (marine white spot) = 280,000 µWs/cm²
According to the Emperor Aquatics website a 40 watt UV sterilizer will provide a zap dose of 180,000 µWs/cm² at a suggested flow rate of 157 gallons per hour (GPH). Is this sterilizer large enough to kill the target organism requiring a zap dose of 280,000 µWs/cm² at our calculated flow rate of 76.7 GPH? A little math will help us find the answer.
(180,000 µWs/cm² / 280,000 µWs/cm²) * 157 GPH = 100.9 GPH
This tells us that we need to decrease the flow through a 40 watt UV sterilizer to 100.9 GPH to achieve the desired zap dose of 280,000 µWs/cm². In additon the minimum flow rate (76.7 GPH) for two system turnovers a day has been met.
============================================
Летальная доза для теронтов криптокариоза - 280000 мкВт*сек/см2.
Причём, следует учитывать, что 280000 мкВт*сек/см2 - это нижняя планка.
Диапазон необходимой летальной дозы облучения - от 280 000 мкВт*сек/см2 до 800000 мкВт*сек/см2.
