how about your ph? after the water change to clear does the pH clib back to original value before you adding 2kg of peat?

nope pH did not go up to original level after adding purigen.

Based on my research, it works when you have water passing thru them. Dumping them in the tank won't work or won't work as well.

It is supposed to polish water as it passes thru the filter. Hope this helps.

yes. i placed my purigen in a fast flowing portion of my sump tank.
good to have multiple layers of stocking... a hole appeared in my purigen bag over time and some purigen got sucked into the return pump. the tank was like having a "snow storm" for awhile
