Yes.
Many people mistakenly refer to clearomizers such as the Protank and Vivi Nova as tanks.
They are more accurately called clearomizer tanks or clearo-tanks. In fact if you take the time to read the FULL descriptions this is what many vendors call them on their websites.
People being people, many get lazy and just call them tanks but this causes confusion.
Calling them a clearo-tank refers to their method of wicking and is a much more accurate description.
It also avoids confusing them with carto tanks which are the original "tanks" created right here on these very forums by talented modders who used plastic syringes, rubber grommets and homemade slotted or punched cartos combined with good-old American ingenuity to bring us something better.
Depending on your device and your
juice you can have drastically different experiences with each.
For instance: Many people who use high VG juices report less than satisfactory results from a clearomizer, especially the top coil ones.
They have less surface area than a carto tank and dont wick thicker
juice as well.In addition to the thicker juice, the top coil clearos are also fighting gravity.
Bottom coil clearomizers do a better job but its been my experience that the flavor of a carto tank is superior to all but dripping and Rebuildable Atomizers or RBAs....which are also sometimes mistakenly called tanks because they too have a juice reservoir.
Hope that clears things up a bit for you.
