I was also going to suggest activated charcoal. I keep mine clear that way. I created a water feature that looks like a continous pouring pot. Inside is a couple of pounds of activated charcoal inside a panty hose leg. The water has to circulate through the charcoal before pouring back into the pond. Works great. Every couple of months I change the charcoal. It only takes a few days to pull the tannin out of the water. You can see the pot in the background. Not a very good picture, but the water should be clear.
