This maybe that chemists opinion...but its definitely not fact. This article clearly shows that treating your fish with PP has a measurable negative effect.
The problem is no one has studied the effects of of long term pp use. Almost all research on it has been done in commercial hatcheries where the goal is not the longevity or long term health of the fish ..its the best methods to turn over a population of fish quickly and profitably.
Its much like how it used to be ok for decades for the poultry industry to use antibiotics prophylactically on chickens.. It did no harm... right? Wrong. It just was more profitable to use it.
We see similar with antibiotics in fish .. there are still discus keepers that routinely use antibiotics as a prophylactic even if the fish are not sick... foolishness at its worst.
I have said it before.. there is no point to using pp regularly and its not needed if you deal with the issues that made you rely on it in the first place. Proper husbandry is the solution.. not throwing caustic chemicals at discus.
