Shoutout to the guy at the Fort Worth flea market who saved my 2 gallon bowl with one weird tip
I was at the flea market off Highway 80 last month hunting for a tiny glass bowl and got to talking with a vendor who keeps shrimp in jars on his kitchen counter. I mentioned my 2 gallon bowl kept growing fuzz on the anthurium roots even after weekly water swaps, and he told me to stop rinsing my sponge filter in tap water because the chlorine was nuking the bacteria every time. He said to just squeeze it out in a cup of tank water during my Sunday changes, and within about 3 weeks the fuzz quit coming back and my shrimp started molting like crazy. I had been doing the tap water rinse for almost a year because some video taught me that, so this was a big face palm moment. Now I keep a little deli cup of tank water next to the bowl on change day, takes ten seconds. Curious if anyone else was taught the tap water thing, or did I just fall for bad advice on my own?
Wait, you rinsed your sponge in tap water for almost a YEAR? I'm sitting here cringing because I did the same thing with my first sponge filter back in the day, straight under the faucet every single week because some guy on YouTube said it was "fine." No wonder my shrimp kept dying off one by one and I could not figure out why. That vendor basically saved your whole colony for free at a flea market, which honestly feels rare. The deli cup trick is so simple it kind of hurts to read.
