Yellow mustard algae & Yellow Treat vs Yellow Out vs Mustard Master

Yellow Out (CHECK ON AMAZON) is an ammonia salt, most likely ammonium chloride and I believe they used ammonium suffate at some point and may have improved on that now.

However, if you check and follow the instructions on the bottle, AND raise the pH to 7.8+, you’ll end up with 2 – 3 ppm of monochloramine in the pool. Monochloramine is the least irritating of the ‘simple’ chloramines or combined chlorines that the swimming pool industry talks about. It is VERY effective against mustard algae.

However, it is still irritating. Many a time, 2-3 ppm can be a bit irritating to every swimmer, and super irritating (high itchy skin rash) to some. Because of that, we recommend closing your pool while it is in use. Then you’ll need to shock over and over again to take out the monochloramine. Plus, if you use an ORP system, you will need to disable it while Yellow Out is in use.

Yellow Treat vs Yellow Out

No doubt, it is effective at removing mustard algae if its instructions are carefully followed and Ph IS RAISED CORRECTLY. I wouldn’t try it as a precautionary measure though. That being said, if you must use it, then do your best to keep others from suffering from the side effects.

PROS

The Monochloramine pool chemical is super effective at killing algae, whether you produce it using Aqua ammonia or Yellow Out.

CONS:

  1. You SHOULD NEVER swim while it is present.
  2. It is difficult to eradicate from the pool.
  3. In some cases, it serves a temporal solution, with mustard algae returning quickly.General note:

Bromide based treatments will convert any chlorine pool to a bromine one, at least for some time. This conversion either partially or completely prevents the chlorine stabilizer in the pool from working. That then makes it loss chlorine gradually to sunlight.
