As far as my knowledge goes, the blacker the water=the better. There is nobody in Thailand and other paddies pulling out the leaves to control the tannins so I think it's okay as long as regular water maintenance is in check 
too much tannin in water?

Almost out of my supply of the API 5 in 1 test strips (Yes yes I know they aren't as accurate as the kit but they are finally almost gone)
After having the wood in the aquariums for a couple weeks now it hasn't done too much to the water results.
Nitrates in all tanks are less then 20 ppm
Nitrites are 0
PH is still around 8.5 in all tanks except 1 which is down to 8.0 (has the largest piece of wood)
KH is still 240 on strip (I don't think I have soft water )
GH is still 180 (in all tanks)
The plants I have are all low light plants under incandescent 10 watt bulbs. I want to pick up water wisteria too but I think that would still be ok with what I have. (and one LED hood not recommended for plants- but they are still doing fine.)
I would like to see what the master test kit has to say about my KH and GH when I pick one up if it goes higher then 240/180.
Good to know it's nothing to freak out about! Thank you everyone.
