So I want to give my Java Fern tank a little boost. With that in mind:
1. What's the best all purpose, easily available additive/fertilizer on the market?
2. I'm always concerned about adding such additives, as I don't want to add harmfull checmicals to my tank - heck I siphon with my mouth when I perform water changes - should I be concerned about this? Whenever I read "iron" on the packaging, or "do not consume", it always scares me off. Am I off base here?
Thanks for your time. I truly do appreciate it.
