i had a sealed seacosystem for abt a year and a half at one point it seemed devoid of life i checked it today and there were loads of tiny creatures and some of the duckweed had grownback. anyway i decided to add some new water, plants and algae from my garden pond and i just want to know if theres anything i can do before i close it again and forget about it on my windowsill for a few months again lol. also dw the window faces north so its never in direct sunlight.

I recommend bringing the water down a bit to increase the surface area of the water. Adding some extra plants like hornwort/elodea wouldn’t hurt. A little direct sunlight also wouldn’t hurt, especially since the organisms that are left are probably ostracods or something. They benefit from direct light.
I usually like hornwort or guppy grass for jars because they’re pretty hardy and lots of little critters love to live/eat/breed in them.
