Using Fish Water To Fertilize Gardens

[Jeff S]

I read about adding nitrogen to soil gardens but there aren't any suggested levels for nitrogen in the form of nitrates. If I want to use fish water to fertilize my gardens what level of nitrates should I dilute too (60-80-160 ppm) to get the most bang for the buck?

Once per week I water all my soil plants with fish water (water I take from my 500 gallon fish tank that has been filtered and nutrient balanced. The rest of the time I use Chlorine free water from the garden font.
