well purigen cant remove everything, quickly, it will become exhausted quicker too. I just did a water change whenever i had the chance, there was a minimum of 3 per week though.
Soak it in bleach for 24hrs, this burns off the nitrogenous waste, then soak in dechlorinator for 8hrs to neautralise the bleach, then in a buffer for 4hrs to lower the pH back to 7
I dont use a buffer though as i dont think it is enough to drastically change the pH of the aquariums water when using such a small amount, some do it to be on the safe side.
Use vinegar as a cheaper alternative, (white if possible as it doesnt smell)
