have pinks. There are some that do seem to be getting that distinct pinkish tint. Most of them seem to be leopards, though. We'll see!
OK. Water change done. Giving 15 minutes for the heater to adjust, and then turning it on. I'll test the water after I do a few things inside the house.
Update on the tank I found in a thrift store:
Here's the whole setup - no heater, no thermometer. Filter & hood light need to be cleaned before I dare try them to find out if they work.
Decor piece #1. I really like this item. The edges are very smooth. It seems worth disinfecting and reusing. The coin is a quarter, for scale.
Decor piece #2: Moderately attractive. Also fairly smooth, but plastic. I'll soak it in a bleach solution and give it a closer examination. It doesn't seem like it'd be safe for bettas, and I like live plants, so I'll probably toss it.
Brand new filter refills. Always useful.
A close up of the filter. Eeeeeeeeeeew.
Cleanup plan: Everything will be scrubbed with plain hot water. That should dissolve most of the solids that are crusting this thing. I may have to do that twice.
After the hot water scrub, I'll do a bleach treatment. The tank and equipment are really
gross, and who knows why this person got rid of it. I'm guessing by the colors of the decor that it was a kid's tank, so the filth is probably due to sheer neglect.
After the bleach treatment, I'll rinse with hot water until the bleach smell disappears.
