I have an Arctic Spas 1400 liter (370 gallons or so) hot tub. I use the 3 step bromine method.
What I've been doing is adding a bit of bleach to the tub after every time I use it. Normally me and my girlfriend are in it every night for about 15 minutes or so. I usually add a bit of bleach right afterwards. Then about once a week I'll add quite a bit of bleach to bring it up to 15 ppm.
Is this what I should be doing, or should I only add bleach after a soak if the bromine levels are quite low?
