Thanks. The pH is right at 7.3 and that is where I want to to stay.

The nitrates are over 80 ppm and I need to do a dilution test to bring them into a measurable range with the API test kit.

We have already cut back on the fish food as we harvested some of the Romaine in the greenhouse and delivered it to a local restaurant this morning along with a bunch of plants in the grow room we removed last Saturday. So now we have even fewer fully grown plants sucking up the nitrates. We replaced the harvested plants with some smaller ones that were waiting to go into the holes. But they take less nitrates than did the larger ones so the fish food reduction was and will be necessary until we can create more planting space.

At least we are getting an idea of how much fish food will grow how many plants once we achieve a balance between fish food and nitrates. From that we can calculate everything else.
