I figured it was time for an update.
Things are still going! None of my goldfish have died, and I added two new ones the other day for a total of 6. They seem cheerful enough, although one of the two new ones seems shy and hides in the cave a lot.
The plants are growing, although nothing edible has appeared yet. The tomatoes plants are all over the place, I hope they don't get any bigger. The bell pepper plants look the nicest, but I'm not really sure what they are supposed to look like, haha. The kale died during a heatwave, and I replaced it with the bottom chunk of some grocery store celery. The celery was going good until I was trying to debug a problem with the bell siphon and I think I snapped apart all of its roots. I also planted some more kale recently, but its still pretty small.
My cheap paper water test strips keep coming out okay, PH 6.5, and no ammonia, nitrates or nitrites any more, so I guess the plants are doing a good job keeping the water clean.
I got my mom to bring me some worms from her garden the last time she came to visit. She accidentally left them out in the sun before coming over so half of them were dead or almost dead. I put the remaining ones into my grow beds and hoped for the best. I kind of figured they would have died off, but the other day I actually saw one crammed up against the side of the growbed! Kind of neat.
Anyway, I'm thinking of building a second growlight(I think I might have enough LED's left over), and getting some proper reflective-stuff to cover the sides and back of the system. Hopefully that will help things grow more. Here are some pictures.
Edit: I spoke too soon. One of my new fish I got died. Probably wasn't that healthy when I bought it, as the other one seems fine.
