This 125 gets way too much sun light, could not go though a summer without it. It is the only one out of my 8 that I use it. sometimes you just need it. unfortunately for me, it was a $175 need.

Calculus has not changed in 7 years, and that's the basic foundation of his work. The CoraLife TurboTwist and the Pentair AquaStep have the advantage over the older technology in that they do improve dwell time, but they compromise other issues as well. Some manufacturers indicate a maximum flow rate, but they don't tell you if that rating is to zap algae, bacteria, fungi or protozoans. If memory serves me correctly, Emperor Aquatics & CoraLife do have charts or graphs on their web sites that show the zap dosage @ various flow rates. However, even with knowing the Zap dose, we still need to use calculus to determine what flow is required to have all the water pass over the UV tube twice per day (at that rate, it is considered that the pathogens are being killed off faster than they can reproduce) - - keep in mind that every drop of water that passes over the UV Light falls back into a tank of contaminated water, hence the need for the calculus.
Marketers have a way of wording things that can often be misleading, yet not create a situation that leaves them open to lawsuits.
Thanks for the challenge to my post . . . this is the only way we can get to the root of anything & I appreciate the reminder of the advances in technology as it helps to keep the "Big Picture" in view.

ACK! He used the 'C' word!!!
For UV filters/sterilisers you need to be careful NOT to exceed flowrates. Water moving too fast does not have enough dwell time and even with optimal conditions, you will not get 100% killrate.
UV filters are just a tool like everything else.
