Installation and Space Requirements
I measured the available space I had before purchasing my tank. A 70-gallon tank is sizable, so I made sure I had enough room for installation, maintenance, and any necessary plumbing. Understanding the installation process—whether it required professional help or could be a DIY project—was also essential for me.
