Purigen Placement in Canister Filter
It is 10:38 EST Sunday 2/6/2011 and I cannot get the site "search" to function. Maybe it is being blocked by the Super Bowl???
Anyway, I have been running a Fluval 305 in my planted 75 Gallon FW tank for many years and in the upper dual compartments, I have a bag of Purigen in each. So it seems to me that all the water passing through the filter has to flow over or through the purigen. I have regenerated these in the past and renewed in the past. My question is " Do I need two bags in the filter like I have been running, or will just one of them suffice and eventually filter the tank water?". There is no question in my mind that the Purigen is working. I can see that the water is clearer, especially after regeneration or replacement. It is just my question of needing one or both sides of the uppermost filter basket.
Thanks for your assistance.
