Not real sure why you want to go 3/4 pvc,... I ran all mine in 1 1/4 " plastic conduit,, so much easier to pull the wires through!

Use some of the $7k you *didn’t* spend on the new tub. (y)
Electrician will be doing the work on Sat and will come back on Sun once the tub is hear and in place assuming we can get it off the trailer and in place haha.

So its in his hands literally. I did order and pick up the materials tonight.

Not completely sure why you want to do the Bromine thing, seems SO complicated compared to Chlorine.

It doesn't sound that bad I don't think. Of course I may feel different once I do it haha. I guess I will just have to see.

Worst case scenario I have to drain and start over and I would be stuck with a few chemicals I don't need.

I'm just hoping no one has any weird allergies or anything that we don't know about.

Bromine isn’t complicated. It is dosed with chlorine just like a chlorine spa. The only downside is no uv stabilization but that doesn’t matter much with a covered spa.
So if a bromine tub is dosed with chlorine.. and you are putting chlorine in a chlorine tub anyway... whats the point of the bromine?? Seems an extra un-needed step..

Bromine is ph stable in to the low 8.0 ph's which gives more protection since ph rise is very common given the aggressive turnover and aeration when in use. Chlorine loses its efficiency in the high ph ranges increasing the chance of infection. Combined bromine or broamines are still an effective sanitizer so even the consumed bromine still will kill germs, albeit less efficiently. Bromine is supposed to be more friendly to skin and plesant to eyes and nose, though this is debatable some people will say the opposite. It is just a different sanitizer and if you were against the use of chlorine for some ridiculous reason you could use MPS to convert the sodium bromide to bromine though there's no reason to do this since it is a known skin sensitizer and costs more than chlorine.

So , to me anyway, sounds like a chlorine tub with some extra stuff in it.. I guess I just dont see the need or understand the set up. No biggie I was just trying to understand, and to each there own. Sounds like more chemicals to buy.

Essentially yes. The only "needed" extra chemical is a thing of sodium bromide for use during setup of the water. You don't need to use a floater with bromine tabs, it is just convenient if you can't trust the spouse or children to check sanitizer level after use. The bromine tabs are essentially the same as if you used 1 inch trichlor tabs with a chlorine spa. But the bromine tabs bond the chlorine to sodium bromide which means your bromine bank will increase over time instead of CYA with trichlor. This isn't much a deal with splash out and carryout on your swim suits. The basic argument is that bromine is a little easier to do due to the ph range and only having to test for total bromine. When operating though, the work involved with bromine vs chlorine is effectively the same so it's a pick your poison thing. In a hot tub instance bromine isn't the evil chemical it is with pools.

Well we are set up and running

temp is up to about 88

ph is 7.8
TA 60
Calcium Hardness is 80

that’s my starting point

I assume time to drop in the bromide to get it started or should I adjust the other levels first.

That’s pretty good! Drop ph to like 7.4 to lower ta a tiny bit more. Go ahead and put the sodium bromide in and circulate for like 15 minutes! Then add like 2 ounces of 10-12.5% bleach and see where that puts you

thx unfortunately haven't found the bleach yet but I do have spaguard enhanced shock

You can use that for now. Try 1 tbsp. I think I used two once when I had that and it was pretty high
alrighty she is 7.4 and still heating.

Looks like I should put some tabs in the floater at this point and then start testing for bromine at some point

Yeah you can put them in there but I would add 1tbsp of that shock first and see what the level is. Then add the floater at like level 3

test bromine correct


ok Bromine tests out at 2.5ppm

Yes try 1 tbsp of shock and circulate for a couple minutes and check. You shouldn’tput the cover on when the bromine is over 10, but you can let it run for a little while to burn off some. I’m not going to lie, I’ve put my cover in when I was over 15 ppm because I screwed up how much I added and it was fine just not ideal. Also I use the 10 ml test and multiply by 1.25. It saves a lot of reagent and it gets you close enough. You want to ideally target 4-8 ppm before each use and at least some left over after soak. Once yoU get used to it you will be able to just top the sanitizer off after soaking. For me it’s about 2 tbsp of chlorine to bring it back up.

roger that and the floater should be set to level 3 and filled with tabs correct (it goes to 10, 11 for Spinal Tap fans)? And does that stay floating when people are in the tub or can it be removed during that time but back in once we get out.

Additional shock being added now, cover is open temp is 92

Slowly but surely getting there I think
