    How do you clean a tank that hasn't been cleaned in a while?

    I've decided that I wanted to help out with my parent's turtle tank. However, I'm afraid that with me doing newly frequent water changes it could harm them. For context, the tank has turtles and goldfish. Which will go into a pond eventually, but it's a big project. I don't want to harm them by...

    Hi, I have a small comet goldfish and two rosy red minnows living in a 10 gal tank. I’ve had the goldfish for over a year and the minnows for about 5 months.

    I screwed up and my goldfish paid the price.

    I screwed up and feel horrible. I went on a week long vacation, I had someone coming in to feed my fish and take care of my other pets. However, I hadn't realized my two snails had died before I left (most likely of old age, they were over two years old). So, two snails were left to decay in the...
