nitros guide said 30 minutes between additions which is what I've tried to follow. I read this post and I think it does refer to pools but it also says 30 min. https://www.troublefreepool.com/threads/how-to-lower-ta.5065/ My ph rises very fast the first few days because the tub keeps running...

I was digging through some other posts and it seems 30 minutes is the suggested waiting period between additions of acid and no less. Nitro's guide and other posts seem to think lowering the ph down to 7 is fine during the balancing process. I've always done it on the same day and didn't know...

How difficult is it to measure a few oz or less when pouring directly from the bottle?

I'm in northern IL. I will stay with full strength then should I decide to use it. I need to figure out some sort of locking vented container for storage. Would it be ok to dilute with water when used or is there any point? Not sure if it would be any safer pouring directly into a measuring cup...

Hello, I purchased a new 300g tub and awaiting delivery. Had a few questions. I might try half strength muriatic this time around. However it does get cold enough to freeze here vs full strength. Does it matter if the bottle freezes? Not sure how likely the bottle would be to burst if frozen...

Those are some good suggestions thank you. I am probably just over thinking things. Our longest power outage was maybe a little more than a day and it was warm. The nice thing about a softub is its very easy to roll it around when empty. I probably wouldnt need to make it anymore complicated...

Hello, This will be my first time using a softub 220 outdoors over winter. I'm sort of close to chicago and we can have mild winters or it can be -20 F every night for weeks. I'm sure the tub can handle that but I had a few more questions. What if we have a power outage that lasts for days...

Well everything I've read and from my own use the TA has to be something like 50 - 60 for the ph to be correct and stay balanced with all the aeration. Or maybe I should say that is the end result after balancing. It takes a afternoon of messing with the tub on a refill since my tap water has...

thank you. I have read it so many times not to go below 7.0 but this helped it click for me. If I'm understanding correctly the acid mixes in and lowers the ph faster than the aeration can raise it back up so this is why we need to wait and use smaller amounts so not to drop below 7? I was also...

Hello Everyone, I have a softub 220. Its time for a refill after being empty for the summer and I had some additional questions. The TA of my tap water is around 375 and calcium is around 275. During initial balancing I have been using dry acid dissolved in water with a separate container. I...

thanks! It was turning into a bubble bath though. When my gf does use the tub she doesn't listen and gets in without taking a shower. Scooping out the suds for a few minutes with a net seems to have reduced the foaming. However most the time I prefer not to use the bubbles unless my gf turns...

I've had mine going for over 3 months and it hasn't clouded up yet. I add chlorine every other day or after every time I use it. I've been going for 1-2 ppm of FC when I go to use the tub. I'm hoping to move it outside soon so I topped it off and re-balanced to get me through another month. It...

The extra chlorine doesn't seem to bother us when we enter the tub but I am trying to get everything figured out so its normally a little lower. After use when I add more and leave the cover off for a while I get a little dizzy when I go back to the basement. My gf complained about being a...

So if 2 people enter the tub (140 gallon) at 1-2 ppm FC for a hour then I would need to put in roughly 10.5 - 11 ounces of bleach so it would be close to 2 on the next use? I was thinking in this small of a tub the FC will come close to zero much faster than a larger one which is also why I...

its a 140 gallon tub and only for my girlfriend and I. We don't use it every day however when we do it can be up to a hour. We used a inflatable tub for about a month before we decided on a upgrade so thats why I was curious about how fragile the vinyl is. Right now my TA is 80 - 100 , out of...

So I just bought a softtub. I have been reading the manual and they suggest only using their chemicals and not using any shock type treatments. It seems the vinyl is sensitive to certain chemicals. So whats the difference from their spa chlorine and ph decreaser compared to what I would find at...
