When I have been adding small amounts of Chlorine (1-3oz) or 31.45 % Muriatic acid (< 1oz), I have been adding them into a bucket of ≈2 gallons of hot tub water, mixing, then pouring slowly over jets on low. Is this overly cautious? Is it fine to just slowly pour these chemicals directly from the small measuring cup, dispersing over a wide area slowly w/o splashing?
