What chemical am I missing?

[Modawg2k]

I use bromine tabs for sanitizing and muriatic acid for pH. Am I missing an other chemicals for my acrylic spa? I noticed that my tub has stayed pretty cloudy after I had a good group of bathers in it.

I think some sort of oxidizer. See if you can make sense out of this: how-do-i-use-bromine-in-my-spa-or-pool-t102.html

There a scary looking thread but I will read up on it, thanks!

You probably aren't using enough bromine. The tabs are usually not enough if you use the spa frequently. You may need to add sodium bromide to create a bromide bank and to add an oxidizer such as chlorine or non-chlorine shock (MPS) after your soak. This assumes you don't have an ozonator. With an ozonator, you usually don't need to add as much oxidizer after each soak.
