Yellow Out vs. Yellow Gone. Which Algaecide is Better? - The Pool Crafters (2024)

Yellow Out and Yellow Gone stand out as two popular choices among pool owners seeking reliable solutions to treat algae. If you’re struggling to pick one out of the two or looking to identify the strengths that set one apart from the other, you’re at the right place.

Moving forward, we’ll discuss the mode of action, effectiveness, ease of use, treatment time and considerations of both Yellow Out and Yellow Gone to find out which one of two emerges as the better option.

So let’s dive right into the details!

Mode Of Action & Effectiveness In Algae Removal

Both Yellow Out and Yellow Gone are ammonia-based algaecides that work by using ammonia to destroy the structure of algae cells. These treatments are particularly helpful in getting rid of yellow algae, which is usually a big challenge for pool owners otherwise. Apart from mustard algae, Yellow Gone and Yellow Out also kill green, pink, and brown algae effectively.

Since both these algaecides offer ammonia based treatment, they raise the alkalinity level in the pool, break down the algae structure and make it impossible for the algae to survive within the initial hours of their application. So overall, both Yellow Out and Yellow Gone share a similar mode of action and turn out equally effective in destroying pool algae.

Yellow Out vs Yellow Gone: Compatibility With Pool Types

Yellow Out works well in salt and salt-chlorinated pools. It is also compatible with pools operating a salt chlorine generator and does absolutely no harm to any pool surface, even the vinyl lined ones. Similarly, Yellow Gone works efficiently in both salt and traditional chlorine pools while also being safe for all types of pool surfaces, including vinyl, concrete, fiberglass, gunite, etc.

In short, Yellow Out and Yellow Gone are versatile algaecides compatible with a wide variety of pool types and surfaces, which means you can use either in your pool without worrying about staining its surface or disrupting the pool water chemistry.

Ease Of Application

While Yellow Gone and Yellow Out both are generally easy to use for pool owners, it is still critical to keep a few things in mind. Neglecting the important details during application can render undesirable and harsh reactions in your pool, which can end up with you not getting the expected outcome or even making things worse.

Before & After Yellow Gone Treatment

An incorrect application of Yellow Out or Yellow Gone can cause the production of dichloramine or nitrogen trichloride instead of monochloramines, both of which are ineffective in killing algae and harmful for the swimmers. With that said, if you follow the instructions on the label, using these algaecides should be a breeze. And the best part about these chemicals is their ability to work in standard pH environments as opposed to traditional algae treatments that require lower pH levels.

Treatment Time

In contrast to traditional algae clearing methods, both Yellow Out and Yellow Gone are fast-acting options to make your pool clean and algae-free in no time. These algaecides start working within 12 to 24 hours of application and can take up to 48 hours for complete circulation. However, due to the irritant nature of chloramines, you must avoid using the pool during the treatment or you may end up with severe skin itching or rashes.

Post Treatment Considerations

Since ammonia treatments, such as Yellow Out or Yellow Gone, generate high amounts of chloramines, you’ll have a few things to take care of post-treatment to get rid of the residual chloramines, which can be a challenge as they’re not easy to remove from the pool.

After using Yellow Out or Yellow Gone, you’ll have to repeatedly shock the pool to get rid of the chloramines effectively and restore the normal balance of your pool water chemistry. All in all, both of these algaecides require the same after-care practices since they share a similar mode of action too.

Price Comparison

Up till now, we haven’t been able to spot a difference between these algaecides, whether it’s in terms of the mode of action, treatment time, or compatibility. But despite the similarities in several, in fact, all aspects, Yellow Out and Yellow Gone are priced slightly differently.

A 2 lb. bottle of Yellow Gone costs around $14 whereas Yellow Out is priced at $21 for the same quantity. Since a 2 lb. bottle of either of these algaecides covers a 15k gallon pool, Yellow Gone clearly provides better value for money.

While the cost difference may not seem substantial upfront, these minor variations can really impact the overall expense of pool maintenance in the long run. So yes, Yellow Gone does get a slight edge over Yellow Out, given they’re the same in all other aspects otherwise.

Yellow Out vs Yellow Gone: Which Is Better?

Being ammonia based algae treatments, both Yellow Out and Yellow Gone share the same mode of action and render similar efficacy when it comes to getting rid of mustard and green algae in the pool. The only distinguishing factor between these two algaecides is their price, with Yellow Gone being the more cost efficient option. For a cost conscious pool owner looking to get the best bang for the buck, Yellow Gone is clearly the better option here. Nonetheless, we can’t take away the fact that Yellow Out is an equally good option too!
