First season with my Bullfrog A7 Signature (Costco) - here's my startup plan, tell me where I'm wrong
Getting my hot tub ready for the season for the first time. I want to get my frogs in a row as a start to take care of this myself (sorry, had to).
I am planning my approach, so this post is to get the experts opinions on my plan so I get this right.
My situation:
- Bullfrog A7 Signature (from Costco), city water
- 800 gallons (I think)
- Pretty much use it daily
- NOT planning on using the FROG SmartChlor cartridges and going manual with liquid chlorine instead
- This is to save money, but I also think they don't really keep my tub chlorinated well anyway
- Currently only have the Bullfrog test strips, which I think are useless if I am not using the SmartChlor system
- DO plan to use the SmartChlor mineral cartridge
My planned order of operations:
- Pipe flush — I've seen Ahh-Some and Spa Flush mentioned. Is this necessary on a relatively new tub, or should I do it regardless?
- Drain then clean the shell
- Clean/replace the filter
- Refill with city water
- Balance the water (before adding any sanitizer)- pH, total alkalinity, calcium hardness.
- Dichlor first? — my understanding is I should start with granular dichlor to build CYA up to around 30 ppm before switching to bleach. Do I have to use Dichlor or can I use liquid bleach?
- Switch to liquid chlorine for maintenance - I plan to use plain unscented chlorine bleach.
- I currently have bleach from the pool store, but I think I can use any bleach as long as it is unscented
- I plan to test before each soak and dose as needed. Is the general rule something like a quarter cup after each use for a tub this size, or is it more nuanced than that?
- Mineral cartridge - I am planning to keep using the Bullfrog mineral cartridge even without the SmartChlor side.
- Worth it, or unnecessary overhead?
My biggest gap — testing:
I think the Bullfrog Uease strips are useless for this approach but I think they are easy to read so I like that type of test strip.
What will be the simplest test kit for getting this dialed in? I haven't always been super skilled at reading some of the testers. I've seen the Taylor K2006 and TF100 recommended here constantly. Are these overkill for a daily home user, or is a good drop test kit actually worth it vs. quality test strips?
Where do you think I'm off base?
I am hoping to get the tub ready this weekend or the next, so any help getting my plans validated and organized in advance is super appreciated!
