Friend of mine uses bromine and they use floater only when going on holidays. For day-to-day use they just just bleach to activate bromine as needed (large dose after the soak, small one every day based on free bromine test). This might be easier and more reliable. Note: this method requires...

I fully agree, love our SWG - but firend's wife claims she is sensitive to chlorine and they like bromine much better. They had some issues with bromine level going down (possibly biofilm) - so I adviced to do ahhsome purge + overnigh loss test. Just not sure what is the expected bromine loss...

Hi everyone. Friends of mine have a bromine hot tub and I was discussing TFP method with them. They will be doing an ahhsome purge soon, but I wonder about Overnigh Bromine Loss Test. In chlorine tub - 25% loss over 24h is considered a very good result. Would 25% be also expected in very clean...

Hi everyone. I wonder if there is one more possibility of why water level allows to disloge more biofilm: air system for jets. Not 100% sure so your comments I welecome. I don't have a blower but venturi system where jets connected to an air mainfold and air valve at top of the spa. I think air...

Occasional drop to zero might not be a problem (for minutes rather than hours), but prolonged FC below your minumum (as calculated by PoolMath for your CYA) could lead to very quick bacterial growh. Scenario I would be woried is: FC drops below minimum, but it takes few hours before it drops to...

I think you are right. Our spa is small (due to space constraints) and I have to keep water level low on fill - so after myself, wife and two kids get in -> it's close to the max. This means that level with no people is low/maybe-undefilled. Some areas of skimmer will not be touched by ahhsome...

Hi guys! I have been doing my scheduled purge and refill (every 3 months) - as always with ahhsome. Purge no1: 3 month old water - quite a bit of green goo discharged: As it was more than I was expecting, decided to dump the water, refill and purge again. Purge no 2: nothing more...

What is your starting FC - are you aiming for minium or target based on CYA? Good to know that dropping to near zero for a short while is not a cardinal sin I thought it is! Thanks!

Going to FC10 was trying to be on a "safe" side as I am allowing water to drop below minimum for a short while. Judging from your comments this is missguided. That's really reassuring and exactly what I was hoping to hear - thank you. Will try to avoid those "mini slams", this sould make easier...

Thanks - your comment is appreciated.

Hi everyone. Over time we found that my wife's skin is susceptible to drying/itching if I stick to "target" values suggested by TFP as we soak. My tub has 30ppm of CYA so: - miniumum is 2ppm FC - target: 4-6 She is much better if we start the soak at 2-3 ppm (rather than 4-6 target), even if...

I do it in around 2 hours. My hot tub is around 760l and water is hard (250 ppm of TA). Overall I need to add around 350g (12oz) of dry acid to drop it to around 80ppm. This takes me around 2 hours to complete. Using pool math I calculated that I need to add 70g of dry acid to drop ph from 7.8...

Hi guys - a bit of an update. I did some experiments tying to get the "sparkle": 1) Started with getting DPD3 test kit for CC to make sure my water clarity is not affected by CC. Initial measurement of CC was 1.5 (12h after last soak) so decided to make a long SLAM to destroy as much CC as...

Some great replies - thank you very much guys! I will purchase the drip just for science and see if it works as advertised, it is very cheap. Will report here any findings. This might be more pernament solution however - thank you!
