    @Fonske do I remember correctly you live in China? Your 'pet market' is different than our 'Petsmart'.

    I do water changes on demand with an incoming RODI line like @Bill Smith envisions. It is the best thing I have ever, ever done to make fishkeeping easier. Boom, water changes on demand!

    Just as @James Croney suspected a deeper airstone allows for greater dissolved oxygen. Back in the 1970s I was taught that what an airstone did was agitate the surface of the water thereby allowing the carbon dioxide to escape, meaning that an airstone didn't actually add much oxygen to the aquarium, it just reduced the amount of carbon dioxide. This appears to be contradicted by these data. But the difference between a shallow airstone (2 inches deep) and a deep airstone (10 inches deep) doesn't seem to be significant. In fact the aquarium with no airstone would appear to have more than enough dissolved oxygen for our fishes requirements. But the airstones definitely create a flow of water that doesn't exist in the aquarium with no airstone. And all 3 aquarium have nothing in floating at the surface. I think today I might add a duckweed cover to each aquarium and see what that does to the numbers. So James, put your airstone where you find it most aesthetically pleasing.

    Just thought readers of this thread would find these 2 tables interesting. and from the Office of Space Science a the University of Wisconsin this handy chart. There is a lot of research on the needs of game fish and commercial food fishes, somewhat less research ornamental fish like we keep.

    When I have received dead or dying fish, the vast majority of the time it was caused by a leak which left the fish with little on no water. I am a big fan of double bagging!

    LED aquarium lights are much better than LED house lights. But you can also used florescent lights as long as you use a bulb made specifically for plants. Whatever kind of light you use, always use one designed for plants, it really does make a difference.

    You undoubtedly do have all kinds of bacteria, microbes, fungus, and what not in your aquarium. I know I do. And thank goodness too because without that part of the world living in our aquariums our fish would die. Mycobacterium is just one more thing not to worry about.

    Here is how to put videos in your posts:

    And you changed your profile picture. And you became about 20 years younger than your previous profile picture. And this picture is just begging to be memed.

    Even ghost shrimp can be good mothers.

    So exciting!

    Fish I have sold recently for $5 per fish to the LFS, were sold by the LFS for $40 a fish. When I worked in a fish store a long time ago, the markup went from 4 to 1 all the way to 10 to 1, just depending on the species. It was a 10 cent fish that would be marked up to a dollar. It is like @Kirsten says, I would ask for more than you think you can get initially and see were the negotiation goes. It really all depends if they need what you have.

    Everything is now calibrated included the dissolved oxygen sensor. The aquarium on the left has an airstone near the bottom. The aquarium in the middle has no airstone. The aquarium on the right has an airstone near the top. Both airstones are powered by new USB Nano pumps with new Ziss airstones torqued to the same tightness. Both airstones are have the same length of tubing between the USB Nano pump and the airstone. Both USB Nano pumps are on the same power source. That's all for tonight. I will start again tomorrow to collect proper data.

    I did! Thank you for the heads up.

    And after some further settling in on the probes, I'm happy.

    Some copper is important for shrimp so you don't want zero copper. There are lots of metals that it are harmful if there is none, but toxic if there is too much. Copper is one these. The main thing shrimp like is a mature aquarium. Copper might be important, but it wouldn't the first thing I worried about.

    The honey tasting people are very serious. Here is a tasting/smell guide for different honeys I have been working on (based on the honey sensory workshop). I thinking of doing one of these for fish tank smells, sort of a fish tank sensory workshop. Any suggestions for different smells are welcomed. I'll take @dpgriffin's girlfriend's 'pond' as a bigger category that could have sub categories. And I just finished draining a 10 gallon aquarium and I would say there are notes of 'moldy chlorophyll' with a slight after taste of 'old leather' (I did end up ingesting some tank water during the siphoning process).

    Smells like old socks, your first girl friend, your grand mother, a kitty litter box, or a Barnes and Noble?

    Finally, replacing the membrane and cleaning the dissolved oxygen sensor.

    It is easy to post photos directly on the Forum. Even cut and paste work! 🙂

    Yes, my first experience with fish was fishing with my dad. Later after I got first aquarium, it just made the fishing more interesting, because I understood the fish better. But I have also lived in a rural area and raised chickens and rabbits for food. You care about the animals in your care, and you kinda wish everyone could live forever and die of old age. But then I get hungry and it turns out I end up putting my needs first. Same as when I built my house on a wooded lot. I love trees, sometimes I read articles on plant neurobiology, but when it came time to build my house, I cut down trees to make space for the house. It is a complex thing being alive and interacting with and something eating other living things.

    Oh yes the Weavers are legendary. I have purchased 'Buckfast' honey bee queens from the Weavers a long time ago. But wait, you said B. Weaver. I think I have purchased honey bees from both Weavers (there might be a rivalry between the 2 Weaver operations). I think I purchased the Buckfast bees back in the 1980s before B. Weaver and R. Weaver split into 2 companies.

    pH probes calibrated. This reading is pretty good. They are all in the same aquarium.
  24. Daniel
    Step 1, Thermometers calibrated. Calibrated to a NIST traceable thermometer accurate to 0.1°F

    And then there are the unknown unknowns when it comes to variables. 🙂
