Re: Aquatic Plants Digest V4 #886

Can I go out on a limb and guess that you don't dose nitrate, and you have
infact 0 nitrate? :) You should keep a nitrate level of 5-10ppm, otherwise
melon swords will turn red and grow akwardly. Depending on the plant
situation, I dose .1ppm of iron daily in my 10 gallon tank, along with 3 ppm
of nitrateand my plants are growing like weeds, and I dont get any more red
leaves from any of my plants, especially the melon sword. keeping 5-10ppm of
nitrate in the tank will also eliminate any algae since most if not all are
caused by limiting nitrates in which plants are unable to utilize
phosphates, so there should always be a measurable amount of nitrate.
