Amano is a master of biological balance; nutrients produced by fish and decomposition match the needs of his plants. He uses supplementation to keep his flora healthy but does not dose more than plants need. In anouther e-forum Marcin Baranowski wrote the following comment about Amano's opinion, "His answer to questions about fertilizing can be summarized like this: "Add the fertilizer only when you see that plants need it and only as much as it's needed. Do not overfeed your plants."" I do not think that Amano would advocate the estimated index system popularized here.dennis said:By all rights there should be BGA and nitrogen deficient plants.
did you notice the TH of 20 ppm?
According to the religious believe to avoid any soft water in our tanks, there should be no healthy plants in his tank.
The KH won't be probably much different neither, so how is he managing sufficient Ca, Mg and most importantly the CO2 concentration?
Thank you for your reply, it's good to hear, that I am not the only one here trying to play with the RO. The reason I use the unit is because I bought it years ago. It was in a time of hopeless algae growing struggle. There was a believe at that time, that the RO might help. Well, it did help, but not enough. Tap water over here smells like a bleach, deadly chloramine, alkaline and sodium.Jay Luto said:A. Of course. Low KH will promote better growth in plants compare to higher KH. - Takashi Amano
Personally I have yet to use R/O water and so far I have been successful with most of the plants. At the same time I never tried it so maybe there is room for improvement.
