New plant -> Cloudy, "tea" colored water?

[LittleBlueFishlets]

I added sprigs of anacharis as a floating plant to each of my three identical tanks yesterday. Today, I noticed that the water in ONE tank is a little cloudy and a slightly 'tea' colored. Any idea why?

Here is more info:
PLANTS:
- This was a bundled anacharis (metal wrap and rubber band) containing 6 sprigs. It was in a plants-only tank at the lfs, along with other plants. I did not see any snails. The water and other plants looked fine.
- Once home, I removed the metal wrap/rubber band, and soaked the plants in tap water for about 6 hours. I then added two sprigs into each of my three tanks, as a floating plant, making sure the roots were submerged.

TANKS:
- The three tanks are identical, and are lined up side-by-side on a table.
- Capacity: 3 gallons each
- Water temp: 79F (consistently)
- 100% water changes done Tuesday night on all tanks.
- Two 'sprigs' of anacharis added, as a floating plant, to each tank on Wednesday morning.
- The tanks are all near the same north-facing window. They do not receive direct sunlight.
- I do not have any additional light for them (yet).

The ONLY difference that I can see is that the sprigs in the other two tanks have slightly more developed roots. The sprigs in the cloudy/tea-colored tank have fewer roots.

Any ideas on what's causing this? What do I do about it? And most importantly - is there any danger to the fish in this tank?

Thanks!

That's really odd. I can't think of why the water in one tank would be different than the other two, especially in such a short time. Is it possible that something else fell into the tank ? You might go ahead and do another water change in any event. If it happens again, I guess it would have to the plant but, it sure doesn't seem likely. Good luck.

Bunches of Anacharis I have seen offered at chain stores is often brown/nearly dead ,to green healthy (when they first arrive).
If brown decaying plant bundle was what you received,,this could be the problem.

Usually, it is because Tannins are being released into the water. Maybe one of your plants contain tannins? I don't know...

Its leeching. Do a wc, check your levels, and wait.

@fish monger - I checked the tank, but I don't see anything else going on. The only thing new is the anacharis. I'll do another WC.

@1077 - The sprigs in the other tanks have some developing roots, but the two in this tank don't. (They are green though.) I didn't notice any 'slimy' sections, but I'll check more carefully. Maybe I'll just pull these two sprigs and put them into a container on their own.

@emeraldmaster - The only live plants in the tanks are the new anacharis. Do they produce tannins?

@Sundancex - What would it be leaching? Tannins? Other stuff?

Thanks, everyone! I'll do a 100% WC today, and recheck the levels...

If I pull the anacharis and put it into its own "isolation" container --> do I need to add any ferts? (Also, do I need to use dechlorinated water?)

Sorry, I don't really know what it is leeching. I just read about something similar, so that is all I know. You can isolate, treat it like you would a "fish" with dechlorinated water. ;) I would dose it with Flourish.
