Add chemicals to your pool at a return jet in a pencil-sized stream.

MA is pretty hefty on the fumes, so I find I have to hold my breath and sometimes step away and add in a couple doses.

Don’t add within 15 mins of adding chlorine.

Far more important than pH is FC -- you need to add chlorine and CYA!

TA is not something to work at. Monitor it, as you need the test result for your pH adjustments.

CYA acts as SPF for your chlorine. You have neither and algae is right around the corner! Head to Walmart and pick up stabilizer (CYA) and either Pool Essentials Liquid Chlorine or regular, unscented bleach, (no splash less, concentrated or Clorox which has polymers) and use your Pool Math to add correct dosage for your pool. Keep asking questions, we love them!

I like to dilute my MA in a 5 gallon bucket of pool water....then add it slowly in front of the return, but out from the steps where my stainless hand guard is.

When I added some MA to my pool earlier this year I did it before I put the ladders into the pool. Stuff is prett corrosive.

We discourage this. You are handling the acid twice and thus can spill it easier. Best to lower to the pool surface and pour slowly at the pool return. With larger pools, you can just estimate how much straight from the jug. Smaller pools may need a plastic measuring cup.

Brush the area if you feel the acid did not get well mixed.

Good call. I should qualify the fact that I have pretty good experience with handling of caustic materials. Regardless of how people do it please people wear protective goggles, and gloves........
