I recently added some java moss to my 20 G tank, my first real plants, and went to the lfs to get some bottled fertalizer... being new I asked the guy working when I should add the fertalizer, how often, how much etc. He bluntly told me he has no idea, that he's not a plant guy and then asked me for $9.77 to pay for it. So... thats my question, I found on form the bottles directions how much to add, but it says nothing about when... im assuming when I do my weekly water change add some in? Or am I totally off here. Thanks alot.
