Suggestions? Will purigen remove tannins and can I get enough for a 55 gallon filter at a decent price? I still need better sponges for it, but I get a lot of leaves in the fall so the water is tea colored and you can't see the bottom.
 
Yes, it does. However, you may need quite a bit of it to do any good. I fully saturated a 100 mL Purigen pouch with driftwood tannins in a 20g tank over a short period of time.
A better investment for next season might be a bird net (possibly in a frame) to spread over the pond. This should catch a majority of fallen leaves.

The pond is located under two oak trees to protect from birds in the summer. I put up netting in the fall, but the leaves still end up in the pond until I pull them out with the net.
 
I couldn't find anything to suggest it would just looking on the internet. Would activated carbon be possible? Say in a mesh bag at filter outflow.
 
Would barley straw help?


I've used that to combat free floating algae.
I googled it and a few hits mentioned activated carbon. I did not note the amount per gallon needed. At that rate, you could try 1 or 2 100 mL bags of Purigen (I know I mentioned the cost effectiveness earlier).
I do wonder if the tannins will decrease over time assuming all leaves have been removed from the water.
 
That's all I could find as well on the straw combating algae. There have been threads on this but only had a quick look.
 
Thanks guys. I've got to get sponges for this filter too. All I had have are a ton of bioballs in two mesh bags. I've got until spring though, everything is in hibernation mode right now.
 
I have a small pond and its under several white and turkey oaks. I know this doesn't help but I gave up keeping leaves out. Im in Florida so really is only a big issue 4 months a year give or take.
Floaters help and so does a pleco

I've heard if a common pleco living in an unheated pond much smaller than mine and wintering over, but I'm not sure if I believe it. My pond is located under two white oaks and meeting is the only thing that keeps leaves off the bottom and allows me to pull them out. I think I will benefit from better filtration this year, too and that should help.
