Recently I bought a used 2 1/2 gallon (bowfront style) intended for BS or possibly a betta. The tank I found out had some wierd looking stuff on the bottom. Like old dried leaf pieces. I tried as hard as possible to clean it off but it didn't come clean and I eventually dumped diluted bleach (now I find out it had cleaner stuff in it too) into the tank to ensure whatever it was, it was not alive. I rinsed the tanks many times and I have been putting new dirty fish water in it every week for the entire week.
I would like to know if this tank is safe. I don't want to get feeder guppies because if it's not safe they die and if it is safe I am stuck with them. Is there anyway I can get quick algae growth in it or something to let me know if it's okay or not?
Also, I got a 5 gallon hex. It had toads in it from the previous owner so I washed it (with dish soap). It has been empty for months. It's usually dry 1-2 days a week and filled with hot water for the other 5-6 days. I rinsed it dozens of times since then and I also put it in a bucket with hot water for a few days. Would you think the tank is safe now?
