Indeed, I for one have used rooibos tea in my previous tank set up to imitate blackwater slightly and I like the look this tea stained water, not everybody like this look.
This is a quote from a well known member, TwoTankAmin -
"Rooibos tea is not really tea, it is a member of the legume family which is only found in S. Africa. It is a very sensitive plant and most of the things being organic would insure were not used would kill the rooibos plant if they were. I was told this by a Bio-Chemistry Prof. who teaches and researches in S. Afr. He has posted pics of the plants growing there on another site. Rooibos can be brewed into tea and the resulting tea can be poured into the tank. It can also be put in a very fine mesh bag in the filter. I normally brew some for every water change and add it to the big can of water I mix up for blackwater tanks. In a filter its a trial and error thing. Start little and work up til the water looks the way you want it too. I have done this too as an extra- I think you will have to replace it in a filter bag about every other weak at best and maybe weekly- I can't say. Rooibos will add many of the same good things and then some found in the catappas. Unlike the almond leaves or the cones, rooibos will not lower pH or soften water. It may actually bump the pH by about .1. It is super at giving a lovely tea stained color to the water."
Quoted from one of my thread i started some time ago and there is also some information about catappa leaves and alder cones, not a great deal of information but will help give you an idea of their benefits in the aquaium.
