Sanitizing a hot tub doesn’t need to be a challenging task. Forget about the liquid detergent solutions and fancy spray bottles that end up consuming lots of cash with no worthwhile results.  

Things are now simple these days. Have you gotten yourself a hot tub automatic chemical dispenser?

Just drop in some chemical tablets, then simply immerse the dispenser in your hot tub. The big task, however, is getting the best equipment to suit your job. Thankfully, our top 9 list of best automatic chemical dispensers will save you time and make your decision making process simple. 

Should I use a floating chlorine dispenser in hot tub?

A floating chlorine dispenser can be an effective and convenient way to dispense chlorine in a hot tub. These devices are designed to release a measured amount of chlorine into the water over time, which can help to maintain a consistent chlorine level and keep the water clean and sanitized.

There are some advantages to using a floating chlorine dispenser in a hot tub:

  • Convenience: A floating chlorine dispenser can be placed in the hot tub and left to dispense chlorine on its own, without the need for manual dosing.
  • Consistency: A floating chlorine dispenser can help to maintain a consistent chlorine level in the water, which can be difficult to achieve manually.
  • Easy to use: Floating chlorine dispensers are easy to use and do not require any special knowledge or equipment.

However, there are also some potential drawbacks to using a floating chlorine dispenser:

  • Cost: Floating chlorine dispensers can be more expensive than other methods of chlorine delivery, such as tablets or liquid chlorine.
  • Limited control: With a floating chlorine dispenser, you have less control over the amount of chlorine that is being released into the water. This can be problematic if the chlorine level needs to be adjusted quickly due to changing water conditions.

Ultimately, whether or not to use a floating chlorine dispenser in your hot tub is a matter of personal preference.
