Are you maintaining more than one fish tank? Do you do water changes one tank at a time? If you answered ‘yes’ to both of these questions, you should consider doing multiple tanks at the same time. Hopefully, you’ve advanced in the hobby to the point that you’re using a Python gravel vacuum or some other brand to perform your water changes.
All you need is two gravel vacuums and two faucets. Then you can perform water changes in parallel.
If all I’m doing is changing water in my tanks, I often do two tanks concurrently, which greatly reduces my maintenance time. I encourage you to consider adding faucet driven gravel vacuums (yes, plural) to your maintenance toolkit. Aqueon and Lee’s are other brands. If you prefer to use gravity-only models, there are plenty of those available too.
