Often we try dozens of filters to try to get tea colored water clear and nothing works. The water is turned that color by leaves usually from oak trees, but other leaves/pollen do the same thing. Here’s how to fix it: Use activated charcoal. Do NOT use charcoal briquets like you use for barbecuing! Go to the aquarium store and get a box

of activated charcoal. Often it comes in a box that looks like a half gallon milk carton. Put the charcoal a cut off panty hose leg and put the resulting tube in your filter. The charcoal ‘washes’ the water and you will have clear water soon. It is a bit expensive, but worth it.
