# How Do I Maintain A Bromine System in My Hot Tub?
*Fresh Water (FW) products are the water care products which Mainely Tubs recommends for complete synchronization and sanitation.*
**Chemical Start Up (for new water):**
1. Balance total alkalinity/pH
2. Balance calcium hardness
3. Add 2 oz packet of [Leisure Time Sodium Bromide](https://estore.mainelytubs.com/products/sodium-bromide-packet-by-leisure-time?_pos=1&_sid=282386cff&_ss=r)
4. Wait 1 day
5. Check and adjust pH level
**Once a Week:**
1. Wipe down the water line with a non-abrasive scrub pad
2. Check total alkalinity and pH using test strips. Adjust with [Freshwater pH/Alk Up](https://estore.mainelytubs.com/products/ph-alk-up-ph-alkalinity-increaser-by-freshwater?_pos=2&_sid=c6e3b6e59&_ss=r) or [Freshwater pH/Alk Down](https://estore.mainelytubs.com/products/ph-alk-down-ph-alkalinity-decreaser-by-freshwater?_pos=3&_sid=c6e3b6e59&_ss=r) as needed, following the directions on the bottle
3. Super oxidize the spa by adding 2 to 3 ounces of [Freshwater MPS Chlorine-Free Oxidizer](https://estore.mainelytubs.com/products/mps-chlorine-free-oxidizer-2lbs-or-5lbs-by-freshwater?_pos=1&_sid=d8792fa83&_ss=r)
4. On a different day than you do the preceding steps (we suggest the next day), add 2 ounces of [Freshwater Stain and Scale](https://estore.mainelytubs.com/products/stain-scale-defense-by-freshwater?_pos=1&_sid=b29d79081&_ss=r).
5. Check your bromine floater to make sure it has enough tablets
6. Rotate filters
**Once a Month:**
1. Remove filter(s) and clean using [Freshwater Instant Filter Cleaner](https://estore.mainelytubs.com/products/instant-filter-cleaner-by-freshwater?_pos=5&_sid=bbef7a1f1&_ss=r), following the directions on the bottle. Be sure to thoroughly rinse filters to remove all trace of cleaner. Filters must be cleaned ***at least*** once a month
2. Clean the cover surface with [Freshwater Cover Shield](https://estore.mainelytubs.com/products/cover-shield-by-freshwater?_pos=1&_sid=f36dfec3f&_ss=r)
An extra set of filters will help with this
**Every 4-6 Months (depending on water quality):**
1. Terminate power to the spa
2. Completely drain the spa per the instructions found in your owner’s manual
3. If needed, clean interior of the spa using [Freshwater SpaShine Hot Tub Shell Cleaner](https://estore.mainelytubs.com/products/spashine-hot-tub-shell-cleaner-by-freshwater?_pos=1&_sid=acf3c0aa0&_ss=r) and a non-abrasive scrub pad
4. Refill the spa using a garden hose placed directly into the gray-capped filter standpipe
5. **REPLACE** the [Continuous Ion Sanitizer Cartridge](https://estore.mainelytubs.com/products/freshwater-ag-continuous-silver-ion-purifier-single-or-auto-ship?_pos=1&_sid=41f76000c&_ss=r) with a new unit
6. Make certain the spa is circulating before allowing the heater to operate
**\*\* ONLY DRAIN & REFILL WHEN TEMPERATURES ARE ABOVE 40F \*\***
*Notes:*
1. When using a bromine floater, you will want to fill the stand pipe with tablets and adjust the dispenser to the number of gallons you have in your tub
2. You may need to shock with Freshwater MPS Chlorine-Free Shock more often if use is high
3. To suppress foaming while in the tub, use [Freshwater Defoamer](https://estore.mainelytubs.com/products/defoamer-reduce-foam-by-freshwater?_pos=1&_sid=2c1cf17f1&_ss=r)
4. For oily films, soap, or heavy bather loads (cloudy water), use [Bright & Clear](https://estore.mainelytubs.com/products/bright-clear-clarifier-by-leisure-time?_pos=1&_sid=3f075e0b6&_ss=r)
5. To remove excess build up in plumbing lines use [Jet Clean](https://estore.mainelytubs.com/products/jet-clean-hot-tub-jet-cleaner-by-leisure-time?_pos=1&_sid=9f85fb5cf&_ss=r) **prior** to draining, follow directions on the bottle
6. For an extra deep clean, you can use [Freshwater Hot Tub Filter Cleaner](https://estore.mainelytubs.com/products/hot-tub-filter-cleaner-by-freshwater?_pos=9&_sid=29927c2e1&_ss=r) to soak the filters overnight
***All recommendations are based on 1-2 people; 2 times per week for a 20 minute soak***
