Okay, as per your requests-
I have increased the KH to 4.5 (via baking soda). The nitrates =5 ppm, phos=.5 ppm. pH is 6.7 and the leaves are bubbling like they never have. I also have added some Kent Botanica nitrogen (enough to raise the nitrates to about 7.5 ppm) and Kent Botanica potassium (I added the amount rec on the bottle 7.5 mls). The store I went to did not have the Seachem stuff. Does anyone have any thoughts on how much potassium to add as I don't have a way to test potassium levels. I was also afraid to add any phosphates because I am afraid what the algae might do. The instructions on the nitrogen bottle is big into the NO3:phos ratio. Any thoughts on this? By the way this tank is 2-3 months old and I am not willing to part with the trickle filter -I have a 20 gal CO2 tank.
Thanks for your time Dave
