Purigen is just too darn big
So I have an azoo palm filter that I've been using with a 100ml bag of purigen, but it's just a little too big for the filter. The bag barely fits in the media chamber and I feel like it stops water too much to make the purigen as effective as it could be. I wanted to make it smaller, but that would require opening the bag. My question is how would I reseal it so little purigen grains don't invade my tank? I thought maybe an all plastic twist tie, but I don't know if that would tie it tight enough. Any thoughts? Should I just leave it as is?
