Your E-Juice’s Impact on Your Sub-Ohm Tank's Performance

Your E-Juice’s Impact on Your Sub-Ohm Tank's Performance

You are sitting at home and having a vaping session with your favorite MOD and sub-ohm tank. Suddenly, you start to taste something a little strange from your e-juice. The flavor isn't quite right and you try to add more vape juice to your tank, but to no avail. You might ask yourself, "What impact is my e-juice having on my sub-ohm tank's performance?". There are several reasons why this could be. You see, this issue is quite common with tank atomizers and can easily be avoided by understanding what goes on inside your atomizer. 


There are a wide variety of e-juice lines out there sold from numerous vendors. A few of the main ingredients that could ruin your tank are malic acid, essential oils, triacetin, cinnamon flavors, and citrus acid. These ingredients were known to lead to cracked cartomizer tanks and upset vapers. Fortunately, the vaping industry has moved onto using glass tanks in most sub-ohm tank atomizers, yet there are rare instances of sub-ohm tanks that use plastic or polycarbonate tanks. If any of these ingredients are inside your plastic tank, be sure to get it replaced soon with a sub-ohm tank that utilizes glass or at least Pyrex. The ingredients have a deteriorating effect on the tank and when combined with heat, the plastic begins to break. This eventually leads to cracking the tank.

There are tons and tons of e-juice brands out there which use high sugar content in their ingredients. These sugars can cause a poor flavor. After a lengthy vaping session, the sugar will be exposed to high heat, caramelizing onto your cotton on the sub-ohm coils. This creates a sugary cotton wick that will remain on your cotton until replaced. Most vapers cannot visually see this, but when this sugary cotton is vaped, the vaper will taste a burning flavor, like a dry vape. The e-juice wicks the cotton through the coils and the sugar will be stuck onto the coils, shortening the coil life. A simple way to prevent this is to only purchase low sugar content vape juices. High vegetable glycerin (VG) in juices function a similar way as VG is highly viscous than propylene glycol (PG). Purchasing lower VG e-juices can prevent this or your tank's coils will suffer.

Do you often leave lots of e-juice in your tank for a long period of time? This exposes your juice to oxidize, but more importantly, allows them to caramelize inside your tank from the oxidation. After e-juice has been left unattended for an amount of time, depending on its ingredient, it could leave stains around the inside of your tank. These stains can provide an off-flavor and create problems when performing maintenance on your tank. While this may not present an issue for vapers who only vape one juice in the same sub-ohm tank, it can create problems when the tank isn’t cleaned after months of juice buildup. 

There is lot of maintenance with sub-ohm tanks that comes with vaping. Sometimes you may feel like you want to give up and return to traditional tanks because of less cleaning and maintenance. Instead of succumbing to that, follow these simple tips to prevent your e-juice from affecting your sub-ohm tank atomizers. Simply cleaning your tank and letting it air dry between switching flavors and every few weeks of use can prevent these issues. Be sure to purchase multiple coil replacements if you change flavors often and avoid dry hits. If tanks are simply too much to fiddle with, there are many different types of atomizers and devices with all-in-one functionality. Find the one you enjoy and take care for it.
