2/3/19- I removed the polishing pads in the filter and replaced them with new ones. You can see the difference between the two in the picture below. The polishing pads on the left are the ones that were in the filter. The ones on the right are the unused polishing pads that I put into the filter today. The purpose of the polishing pads is to remove micro-particles from the water.

WATER QUALITY UPDATE (late morning)

• pH = 6.4-6.6 (was 6.8 first thing in the morning)*
• Ammonia = 0.25 ppm 
• Nitrates =40 ppm
• Nitrites = 0 ppm
• KH = less than 50 ppm
• GH = 71.6 ppm

A consistent trend I've found is that the pH of water when I first open up the trout tank in the morning is 6.8. After a few hours of the fish swimming around and eating, the pH drops to 6.6. This makes sense because as fish move around move, they are respiring, which means they are taking in oxygen and releasing carbon dioxide to the water. Carbon dioxide dissolved in water causes the water to be acidic.

12/30/18- 2 trout were removed. 1 gram of size 1 food was given.

• Ammonia = 0.25 ppm
• Nitrites = 0 ppm
• Nitrates = 20-40 ppm

4 gallon water change was done at the end of the day since the pH looked lower than usual.

12/23/18- Since the filter has been running for a few months, it was time to begin cleaning out the filter canister. Unfortunately, I discovered that about 100 fish had been sucked up the filter when I had the black cover on it instead of the softer mesh cover, which it has now.
WATER QUALITY UPDATE

• pH = 6.8

Number = about 180 live trout
12/28/18- Four trout were removed. 
WATER QUALITY UPDATE

I fed 1.0 grams of size 0/1 food this morning. At the end of the day, the pH was 6.6. It seems to be a trend that the pH is higher in the morning than in the afternoon.
12/18/17- I removed four fish.

I did a 6 gallon water change, 3 fish were removed. 
Number = 298 live trout (218 dead since Day 1)
​12/21/17- No food was given today in preparation of the long break. This way the ammonia levels and nitrates don't rise too high.
WATER QUALITY UPDATE

• pH = 6.6

I did a 6 gallon water change to pull out more fish poop to help clean the water, particularly since the pH went back down to 6.6. The pH of our tap water is about 7.4, so a water change will slightly raise the pH.
One fish was removed.
Number = 297 live trout (219 dead since Day 1)
