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...

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...

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...

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...

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...

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 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...

So I've had the hot tub online since the middle of October with no issues, crystal clear water, checking water all the time. In the last couple weeks I noticed some itchy red dots on the insides of my biceps and my sides. They got worse and turned into a really itchy rash type thing. I haven't...

LOL I just posted the other week about too low chlorine levels. Chlorine levels were good. Today I shocked the spa. This evening the chlorine levels are too high. Just now I took the cover off and am running the jets, hopefully some of the chlorine will evaporate? FCl is 10 Total Cl is a way...

Just started setting up this hot tub for the first time. It comes factory-programmed with 4 x 30min cycles per day. I've heard that 4 hours per day is ideal? So I've jacked it up to 4 x 1hr cycles, is this good? Thanks.

I just noticed, for the first time, excuse my noobness as this is all new to me, but there's a barrier in front of the skimmer where the filter is. And this barrier can slide up and down. I noticed it was up almost all the way, so when I slid it down suddenly a lot more water was going in there...

Hi all! First of all this is my first time on here, and thanks in advance for any help you can give me! A couple days ago I just filled our 1500L hot tub for the first time. We just bought our house in the beginning of the year and the hot tub was currently running and maintained by a spa...
