I assume that you have connected the Pentek housing to the outflow of the canister filter so less dirt goes through the Pentek. Correct?
How do you disconnect the Pentek for cleaning? Are there valves on both sides of it to shut the water off during cleaning?
How often do you have to charge the Purigen?
Have you seen any definite difference in the tank after you installed the Pentek housing?
Great questions Nikolay
I have two out of three reactors plumbed in post filter and this is the best way to do it. The exception is on my 90 gallon where it is on a separate loop with my Mazzei CO2 injector ( prior to the injector) This was the proto type and the pleated filter was plumbed in originally to prevent the mazzei from getting clogged. I have to clean this every two weeks. But this this tank has my biggest bioload and the purigen is pretty brown after two weeks!
I do have ball valves on both sides so I can shut the flow off and remove the housing for cleaning. The small reactor use the Ehiem double disconnect fittings.
As for the frequency of cleaning, The one reactor on the 90 gallon is every two weeks. The reactor on my 60 gallon has a 50 micron pleated filter plumbed ahead of the reactor and only gets changed when the purigen looks nice and brown, about every three to 4 weeks. This is faster than before when I had purigen in a media bag, but it just means that I am removing more organic waste. This is a light bio load tank - 4 red neon gobies, 15 threadfins, (both thanks to Invertz Factory) and two species of Sulawesi shrimp. I want this tank to be oligotrophic so the purigen is imprtant. It is working great! The new small reactor is on a ten gallon and is less than a week old so we will see.
As for differences, The water is very clear, that is expected with this product. The Sulawesi tanks are even more dependant. The shrimp are sensitive, the want clean water but they are sensitive to large water changes. This keeps things stable and allows me to do 10% water changes.
Hope this rambling reply helps
