I've been improving my knowledge of (non-aquatic) container gardening, and have learned a bit about NPK ratios and macro+micro nutrients when it comes to terrestrial plants. I've been using a dilute solution of a complete liquid fertilizer called Foliage Pro 9-3-6 on my potted plants with great success.
I recently placed some excess frogbit from my aquarium in a 1/4tsp/gal solution of Foliage Pro 9-3-6 and within a week it was green and thriving (it was struggling before, see next paragraph).
I've been tinkering with separate bottles of Seachem Nitrogen and Phosphorous to try and address the macronutrient deficiency in my aquarium (I use a RO/spring water mix bc my tap is awful). I'm seeing significant improvement, but the frogbit in Foliage Pro is far surpassing my results.
Is there any reason I shouldn't use Foliage Pro in an aquarium with fish/inverts?
I understand that complete fertilizers risk the precipitation of iron with phosphorous, so I'm prepared to dose iron separately or try to work out another plan for that if the FP doesn't supply enough.
Here is the data on FP: (contents listed on second tab)
I know that Foliage Pro does NOT contain urea. Are there other substances in the mix that could be harmful, or that I should look out for?
This poster was investigating FP 9-2-6 for aquatic use until she "was told that ammonia based fertilizers aren't good for aquariums."
What does this mean? Is it true? If so, could the problem be addressed using Prime?
Thanks for your help!!!
