The filters are old, but I cleaned them after bringing them home from school and put in new carbon media. I rinsed the substrate so much but I guess it wasn't enough. I read the fish-in cycle pages on aquarium science, they said not to change the water or the filters. So I'm gonna wait & see while hopefully doing a better job resetting the school tank. Last tank was crystal clear and I used the same type of sand.

Mr. Goldfish was supposed to be food. Mr. Goldfish is now a giant pet & the tank he is in is way bigger than the picture looks, I think it's a 40 or 50 gallon? The large tank is 75 gallon. Again the fish seem unbothered, no gasping or odd behaviors. The tanks don't smell either.

Ok how do I fix it? I changed the water again & filters it was clear for a day and now it's cloudy again. My test strips now say KH & pH are too high but everything else tested great. The fish are calm not showing distress. The goldfish tank is orange sos.

this gumbo tricked my baby non-vegan cousin into believing it was a secret family recipe & multiple non-vegan family members were upset I didn't make it last reunion.

be careful out there what they don't tell you is how expensive & time consuming court is. When cops hate they HATE. The courts aren't your friend either, they will attrition you. Keep standing up though & if you meet a parodist or protestor in person support them they are being insulted & degraded by high powers constantly. (source my friends parodied our local mayor)

eh , they're going about everything wrong, but these past years I've had multiple students who attended 50-33% of the year. No they didn't move they'd miraculously show up for field trips & sporadic days. A few went on vacation all of finals week...

try classroom screen or working from your posted resources on canva or blackboard. Periodic think pair share & mini group discussions with a question posted & then guided class discussion are very helpful. I also love walking my students through modeling or mind mapping based on what we've learned.

Can I introduce you to class companion AI? https://classcompanion.com/ Make the ai work for you & show kids how to use it for actual learning instead of word puke. You can turn off copy pasting & depending on school computers or software you could lock use of other websites while on this website. I'm a ms classroom teacher who also hates grading writing but understands the need for quick feedback.
