Okay. Here we go again. Wednesday and we're working on three tanks. Have a 55 gallon finished and will work on the outdoor 300 and the government tank. Water changes for these three and a little plant work. i guess I'm a little on the lazy side. I like natural tanks. Those are tanks you set up and just allow to do their thing naturally. The only thing we do, is change half the water every few days. Most people wouldn't go for a tank like mine, it can get overgrown and a bit messy, but you can't complain about poor water conditions. Half or many times more water is removed and replaced at least every week or even five to six days. The largest tank gets two large water changes weekly. If you keep large Goldfish and Koi, you should change out the water more often.
