Hi! So I've done the bleach method for a while now, and it's definitely cheaper, but it's very tedious. I found I was adding bleach twice a day, and then always having to remember to add after we would come out of the hot tub. There were days I neglected, then found out that FC was pretty much...

Thanks for all the tips guys! I wasn't really wanting to spend more money on scales and stuff, it seems a lot of work to measure out on scales every time I dose. What really doesn't make any sense, is why on the container itself, why the manufacturer of the granules doesn't just say how many...

So I really hate that I have no clue what grams to teaspoons are? The trouble free calculator uses grams, but that is a weight measurement, not a volume one! Even the dichlor bottle says "add 20g".well what is that? The closest I've got was to google how many grams of sugar is in a teaspoon as...

Interesting good to know! Yeah I wonder if it was that, I mean I would sit in the corner and have the jets blast at my back and sides for a long time every day, that might have caused the issue I'm thinking. - - - Updated - - - Just did the Ahh-some treatment....holy cow the foam was almost...

Wow that's 6 ppm a month. So I should really be testing CYA once a month or just the first month after and then add dichlor to top it up...once I know how much it depletes I don't have to test any more. Thanks for the info!

Yeah I definitely think it was caused from when I was using trichlor tabs...and they dissolve so much there was insane amounts of CYA in there. But about losing the CYA, I thought it stayed in the water until it was dumped? But I guess if you have lots of splash out and are replacing water...

The only bleach Costco sells, so I'm sure they go through a lot of turn over and it shouldn't be old. Chlorox. - - - Updated - - - Yeah it's not splashless, I already made that mistake and it makes a lot of bubbles. But it's the stuff Costco sells, Chlorox. I wonder where I can buy a brand...

So really I should just hook it back up then. It seems to run all the time though, because I see a trail of tiny bubble always coming up when it's hooked up. Unless it just puts in air all the time and then activates the ozonator when the pump is on.

Ok, so far I have to add about 200 ml of bleach per day. And my tub is a Sundance Calypso 6 seater, I think it's 1500 L. PoolMath tells me only to add 78ml or so but I find I have to over double that to get my goal FC

So I checked it in the early afternoon, it was about 2 FC. So I added 200 ml of bleach and tested it at 6.5 FC. On the PoolMath calculator if I have 2 and have a goal of 6.5 it tells me I only have to add 78 ml. So I'm finding I'm having to add over twice what the calculator says to add...

I have an ozonater in a tub that was purchased back in '94. The nipple broke off of it and so I put a new one on. I've had a few people tell me just to unhook it from the power supply and seal the air intake. So I've done that. Now I don't see any little bubbles coming up from the bottom like...

Keep adding more dichlor till the FC holds? I've been testing the CYA and it comes to about 33, but maybe that's not enough to hold it good?

Did the dichlor then bleach method after dumping and doing a clean. Seems like the FC gets used up very quickly or something is wrong with the calculations. I went in again after taking a week or so off and the itchy spots and rash came back again very quickly :( So I don't know what's wrong...

So tonight after we were in the tub for about 30 min, I tested it at only 0.5 FC and 1 CC. So putting this into the pool calculator with a 2500 L size (probably not that big, only 1500 L), it recommended 188 ml to raise the FC to 7, so I added that, after running the pump for about 15-20 minutes...

Good to know thanks! I've disconnected it, don't see the little bubbles trailing up any more and it's quieter. I'll see how this affects the water chemistry with regards to the FC being used up...

We haven't used it for a few days. I run the pump when I'm adding the bleach, so it runs for about 15 minutes and then I test it. I already did a plumbing clean and drain several weeks ago too. Here's a pic of the bleach bottle: Microsoft OneDrive - Access files anywhere. Create docs with free...

So frustrating, there is NOTHING regarding percentage on the bottle, doesn't list ingredients and says to go to The Clorox Company | Products | Ingredients Inside for the ingredients where this bottle is not listed. It's a Chlorox "Original" and in small print it says "Concentrated Bleach" I...

So I'm finding I have to add a lot of bleach, more than double the PoolMath calculator recommends. For example, this morning I had 2.5 FC, I put 7.5 FC as a goal and added 130 ml. (assuming 2500 L). I tested 15 minutes later and only got 4.5 FC! Right now my CYA is about 35 or so. TC at 1. Is it...

LOL we don't get much sun in the winter, but yeah it's usually much brighter outside. I'll do the pouring back and forth from the mixing bottle. Seems to use a lot of the reagent! I guess that's why it comes with 2 bottles.

I know some people have poorer eyesight than others, but when I was filling the test tube and looking till when the dot disappears, it seemed to have disappeared--then I took it over to brighter daylight and it was very faintly still there, like if I closed one eye I could still barely see a...

Pool Calculator, wrong hot tub volume?? So I just got the Taylor K-2006, works pretty good! Now I'm seeing that I am only putting half the amount of chlorine I should have. So I had 1 ppm FC this morning, I did the PoolMath to add 105 ml of concentrated bleach to get to goal of 7. However, when...

Don't really feel like doing that in -10C weather. Will have to wait.

I just did a drain and refill the other week, so probably will just wait for it to go away as I'm sure it's not harming anything.

I'm doing the dichlor then bleach method, first time I added bleach today and noticed that there was bubbles on the surface of the water right away after adding the bleach (had the jets on when adding it). Then I noticed that the bleach I was using was "splash-less" and it was more thick, so...

So uses up the free chlorine too quickly without using the tub or any load? Should I just unhook the air hose from it then?

Wow thanks that explains everything well regarding the shocking and bleach! So I I'm doing good so far, got it to 5 ppm FC the first night, today it dropped to 3, so I just fed it more dichlor to get back to 5. So right now, I'll have put in 7ppm dichlor total :) Oh by the way, it was...

Since the tub was bought in 1994, should I assume that it's never been replaced and just replace it? Just wondering how much a test kit would be to test it?

So I cleaned, drained, and re-filled my hot tub. Just waiting for it to heat up before adding anything right now. (Cold outside, water was 45F when filling) After getting itchy rash, experiencing way too high CYA, trying to lower ph, I want to switch the dichlor & bleach method but have a few...

Opened the side panel today to start draining and noticed that there was an air hose disconnected. Upon further investigation I found that the plastic nipple that attaches to the ozone injector had broken off. So the hot tub hasn't been getting oxidized! I replaced the nipple, cut the hose...

Yeah I was going to refill it right away after draining. It's supposed to be 2 tomorrow, 0 and 1 the following days so that would be fine. I can't find any Ahh Some in Canada, Amazon.ca has non in stock. Plus I'd hate to have to wait weeks for it to come in and not using the hot tub :( No...
