Pool School says to add acid in front of a return. However I only have in floor popups. What's the best way? In the past I've just thrown in cups of acid in different places of the pool to spread out the acid. There's a guy on here who first dilutes a cup of acid in a bucket of water and then throws that in the pool which seems like the best technique. In the PS Lowering TA article, a point is made about adding "slugs" without really defining what they are or used for. It's an advanced point. After some research it seems that slugs are adding the acid all at once and that's bad because one can etch the pool, damage equipment,etc. And that people thought adding all the acid at once could make the process work better. It's a method that's shown to be ineffectual. For the newbie all we need to know is the correct method to add the acid and that's not stated very well anywhere either in the Lowering TA article or in the Recommended Pool Chemicals Article.
I don't think my SWG is providing enough aeration. I've been trying to lower my chlorine levels as well so I've got 5% SWG for 9 hours. I think I should also run my spa aeration. But for how long?
How does the SWG create aeration? Does the SWG need to be generating chlorine aeration to work? Probably so, and since I have a low percentage setting then there won't be much aeration.
