Tom,
 The nitrates in my tank are at 10 ppm. I add K acouple of times a week using 
sechem potassium. I recently had to bring the Gh and Kh down from about 11dh 
down to about 5 and 3 . I also dose weekly with trace elements and iron from 
the sechem line. I also noticed today that the new growth on my sword plants 
is very light. co2 is about 35ppm. The change in hardness took place with 
small daily water changes over a period of 1 week. Could the change in 
hardness contribute to the problem? Some of the hygros. in the tank have all 
but stopped growing. The only thing that seems to be doing well is the 
algae(never  a big problem in the past) It seems to me that I have drasticly 
upset the balance  in the tank and have no idea what to do to get it back. 
Any ideas are greatly appreciated!!
