3/21/19-  I gave the trout 4.0 grams of size 2 food. Students did a 8 gallon water change.
3/22/19-  I gave the trout 4.3 grams of size 2 food. I added 20 mL of Nitrifying Bactera.
WATER QUALITY UPDATE (before food, taken in the afternoon)

• pH = 6.4
• Ammonia = 1.0 ppm

• Nitrates = 40 ppm

3/11/19- 4.0 grams of size 2 food was fed to the trout. The pH was 6.0. An 8-gallon water change was done in the afternoon, and I removed the chiller cover to clean it.
3/12/19- 4.0 grams of size 2 food was fed to the trout. The pH was 6.4.
3/13/19- 4.0 grams of size 2 food was fed to the trout. The pH was 6.0.

• Nitrites = 0 ppm
• Nitrates = 80 ppm

15 mL of Special Blend was added.

3/4/2019- 4.0 grams of size 2 fish food were fed to the trout. The pH of the water was 6.0, and the concentration of nitrites was 0 ppm, which suggests that the addition of nitrifying bacteria and Special Blend bacteria helped reduce the concentration of nitrites.
3/5/2019- 4.0 grams of size 2 fish food were fed to the trout. The pH of the water was 6.4.
3/6/2019- 4.0 grams of size 2 fish food were fed to the trout. The pH of the water was 6.4. Check out the slow-motion video of the trout! https://youtu.be/GlYAkHE3uRg
3/7/2019- 4.0 grams of size 2 fish food were fed to the trout. The pH of the water was 6.0. I also did an 8-gallon water change. I also added 20 mL of Nitrifying Bacteria.
3/8/2019- 4.0 grams of size 2 fish food were fed to the trout. The pH of the water was 6.4.
WATER QUALITY

• pH = 6.0-6.4
• Ammonia = 0.25-0.50 ppm
  
• Nitrites = 0 ppm
  
• Nitrates = 40 ppm
  

2/25/19- The pH of the water first thing in the morning was 6.4. I fed 3.2 grams of size 2 food to the trout. The pH of the water at the end of the day was 6.0.
2/26/19- The pH of the water first thing in the morning was 6.4. I fed 3.5 grams of size 2 food to the trout. A 6-gallon water change was done in the afternoon.
2/27/19- The pH of the water first thing in the morning was 6.4. I fed 3.2 grams of size 2 food to the trout. 
2/28/19- The pH of the water first thing in the morning was 6.4. I fed 3.5 grams of size 2 food to the trout. 
03/01/19- The pH of the water first thing in the morning was 6.0. I fed 4.0 grams of size 2 food to the trout. At noon, I fed 2.0 grams of size 2 food. It appears that the larger fish still have extended bellies, which suggests that the larger fish are still eating the smaller fish.
WATER QUALITY

• pH = 6.0-6.4
• Ammoni = 0.25 ppm
• Nitrites = 0.25 ppm
  
• Nitrates = 40-80 ppm
  

I added of 15 mL Special Blend and 15 mL of Nitrifying Bacteria to the tank.

2/17/19- I fed 3.5 grams of size 2 food to the trout. The pH before feeding was 6.4-6.6, and the Nitrate concentration was about 40 ppm. I added 5 mL of Special Blend Bacteria to the tank.
2/19/19- I fed 3.0 grams of size 2 food to the trout. 
2/21/19- I fed 3.0 grams of size 2 food to the trout. The pH at the end of the day was 6.0, so I did a 6 gallon water change. I also added 20 mL of Nitrifying bacteria.
2/22/19- The pH when I first came in was 6.4. I fed 3.0 grams of size 2 food to the trout.
