Lots of Nitrate

Water Chemistry Results - 05/14

Last week when I tested my water chemistry, my pH was about 8.0. Ammonia was at 0.25 ppm, nitrite was at 0.25 ppm, and nitrate was about 40 ppm.

So the past week I added 1-2 tablespoons of 'pH down' morning and night, testing the pH as I went. (Didn't bother doing all the tests each day, since the ammonia-nitrite-nitrate series of tests take about 10 minutes to complete, whereas pH is immediate.)

Happily, I've gotten my pH down to 6.6.

Unhappily, my nitrite and nitrate have shot up.

Happily, the remedy for high nitrate is to plant more plants. So here are the new additions:


Red Sails Lettuce

Cucumbers (3 plants)

Sequoia strawberry (3 plants)

Better Belle pepper

Cherry tomato

Butter Crunch lettuce

Next project: finish enclosing the ends of the greenhouse...

Someone's been eating the cabbage...


  1. The plants look great. Thanks for sharing.

    Do you have any ideas how I can test ammonia in my fish tank that has been teated with Cloram X? I can't see to find a kit that will actuallly register ammonia in my fish tank. I am sure it's there because I have nitrites, but the readily available tests API, PondCare, etc. won't register any ammonia.

    The nitrites measure .25 on my chart.

  2. Huh... I've not run into that problem, myself. But Sylvia Bernstein had a post over at talking about "The Case of the Missing Ammonia."

    Good luck!
