​

In the picture below, you can see how much fish waste and excess food get pulled in toward the filter intake. Once a week, Mrs. Daniel removes this cover and washes off the waste. Previously, the cover was there to make sure smaller fish didn't get sucked into the filter. Since the fish are bigger now, it acts as an easy way to trap waste. It's easier to remove the filter cover than to clean the inside of the filter tank.

Water quality tests were done at recess today, and since there is elevated nitrites, I need to add more of the Nitrifying Bacteria. However, afterschool, students will be doing a 4 gallon water change to help combat the increase in nitrates and nitrites.​

01/02/20- I removed 7 dead trout fry from the tank, most of whom had been sucked near the filter, and released the rest of the trout fry still in the basket into the rest of the tank. There was one dead fry in the basket.

12/27/19- I came into school on Friday morning to check on the trout and give them 0.7 grams of size 1 food. Many of the trout had left the basket, but some remained. I didn't see any dead fish yet.

12/17/19- 4 dead trout fry were removed. I've noticed that the fish that have died look like they haven't been eating. Many of the fish that are lively in the tank are developing a bit of a belly (fat storage). This means I'm probably feeding the fish more than they need, but this will help them survive Christmas break when I'm not feeding them everyday.
​Fish waste was removed using a pipette. 0.7 grams of size 0/1 food were fed, with a heavier fraction of size 1 food in the mix.

12/20/19-​Fish waste was removed using a pipette.  I released some of the more active fish into the rest of the tank, but I'm keeping the less mobile fry in the basket. I did a 2 gallon water change after releasing the fish because I noticed a build up of some bacteria at the bottom. 10 mL of Nitrifying Bacteria was added after the water change. 0.5 grams of size 1 food was fed to the trout.
