    A little bit of maxicrop with iron might fit the bill. It may turn your water dark for a while, but should clear up in a day or so. The need for added nutrients is also dependent on what you are growing - greens should be ok with just the fish water, whereas fruiting plants need more.

    If my Nitrates are high, as long as they do not go below 80 ppm would I need to add anything extra?

    Nitrates were around 200 ppm...hard to tell how high, but too high. So I started doing water exchanges to lower it but my well water has a PH of 8.4 ppm. Which brought my FT. PH up to 8.2 ppm and I did dropped my nitrates down to maybe 160 ppm.

    I stopped doing the water exchanges and just planted my GB's with a lot more plants to use up my high level of Nitrates. I also back off on the fish food until the levels return to a more acceptable level.

    Plants need more than nitrates (other micro-nutrients should definitely be present in your system) but to what degree will depend on the plant. I'd just sit back and let your plants indicate if you should supplement.
