    In Portland Or we have had the driest summer in our recorded history. Yesterday we finally had much needed drenching rains - pretty exciting stuff for us! This morning I went out to check the newly "remodeled" pond and it looks like a pot of strongly brewed tea. YUCK! On the bright side it does make for some lovely reflections. Time to get the nets up.

    Welcome, from what I hear as long as the water conditions are right (nitrate, nitrite, ammonia, and what not)...tea color is okay. True nice pics.

    Hi. Glad you got some rain. From what I hear the smoke now is pretty much gone now and you folks can enjoy the outdoors again. I have had tea colored water in my old pond from my neighbor's cottonwood tree that dropped leaves into it. With enough water changes it eventually went away.

    Very true - there are definitely worse things!

    Bacteria will eventually consume the humic substances (which includes tannins) and Telion is right, the tea colour provides some anti algal and antibacterial properties to your pond water in the meantime.

    I had bright green water, then one week it cleared up, now I have brown water. For me personally I like the brown tinted water as it looks very natural. I have a lot to learn about water quality so I just keep on testing, so long as tests are good, fish are doing well I leave it alone.

    Algae control is a good silver lining. I don't mind light brown, but right now the color is so dark I can't see below about 8". I know it will clear up eventually with charcoal and water changes. I won't worry too much about it since leaf fall is about to begin and I will put up the netting this coming week. At least the wildfire smoke is gone and we don't have hurricanes to worry about! :)

    Make sure you have good water circulation and aeration - the bacteria will be busy.
    Also, the humic substances protect your fish from sunburn (mechanically, not chemically) that can happen if the water is too clear and the fish have nowhere to hide.
