Hi everyone, I just received my Nautilus and was reading the directions and it notes that the maximum chlorine level for operation with the Nautilus is 4 ppm. This is a bummer because I just put chlorine in this afternoon and it's probably about 6 ppm right now, so that means I can't use it...

We just went to our local pool store where they sell the dolphin. They only had three.. The m200, m400, and one that said supreme (can't remember what came after the word supreme). Anyway the m400 was 1200.00 dollars I think but I can't find reviews or anything about the m200 or the other one...

I never noticed this before, probably because I always used liquid chlorine and thus entered in 12.5% in the calculator when calculating FC, but why does it say "trade" when you enter say 12.5% for example (for FC) in the calculator next to the percentage, but if you enter 8.25% it says "weight."

I just opened: pH =7.2 FC = 0 CYA = less than 20, perhaps even 0. CC =.5 TA = 60 CH = 80-90 The same thing happened last year where I have no CYA, but last year I had CCs so I slammed, assuming it converted to ammonia. The water is clear. Should I go ahead and adjust CYA to 30 and then add...

I have been here for two years so far (love this website!) The past two years I have used liquid chlorine, but I know bleach is also recommended for FC. I have never used bleach before and we are opening the pool tomorrow. I have no liquid chlorine at the moment and have to run out tonight in...

Hi, We are planning an overnight trip: leaving early in the morning, staying overnight, and then coming home later the next evening. We don't use the chlorinator ever. We had an issue with it two years ago and I don't want to use it, especially when we are not home (not an option). We use...

I never had issues with figuring out our pH using the basic OTO test kit for pH and chlorine. Well, today, I am having a major issue determining what our pH is as I have never seen this color before. Yesterday, our pH was fine and is usually somewhere around 7.6 or so, but today, it is a more...

Our sand filter is 14 years old (Sparco) and it needs to be replaced before we put more money into it. (This was the filter of the previous owner so we had no choice in that matter, but overall, this filter has never given us issues until now.) The pool place near us gave us a quote for...

FC: 3 CC: 0 TA: 60/70 pH: 7.5-7.6 CYA: 30 I feel like I am having to constantly add liquid chlorine maybe twice a day to keep it a tad above my target (do not want it going near my minimum;)) We get a lot of sun (on sunny days of course). With a CYA of 30, and my other numbers as above, would...

Is it possible there is still something in the water absorbing my chlorine even when it has been completely clear the past few days? Just wondering if maybe there is a testing error on my part, either last night or this morning. My pool is crystal, crystal clear (and has been since opening...

I have searched some older posts on this topic. I was wondering what your opinion is on the liquid solar covers as to whether they are worth it or not, and whether they are safe to use when small children use the pool (worried about them drinking the water, etc). My husband just picked some...

I have 2 boxes full of liquid chlorine left over from last season (has been stored in the garage). Anyone have an idea how effective it is at this point?

Okay, filter has been running about 1 1/2 hours. Here's what I have: FC: 0 TA: 50 pH: 7.2 CYA: <20 CH: 120 So, what do I address first? Last year, upon opening, our CYA was in the 40s but now it is well below 20 (may even be 0). The dot never disappeared. I noticed the recommended range is...

Can you shock the pool after adding dry acid a bit earlier? I am in the process of lowering my pH slightly so I can shock the pool. I added dry acid about 1 1/2 hours ago and am hesitant to start shocking tonight because of the dry acid. Should I wait to shock until tomorrow to let the acid...

I have been keeping an eye on my TA, which has been steady around 70 for a while. Our pH creeps us, leading me to have to add acid once a week or so. It has just finished raining here and the past few days I have been watching our pH creep up, preparing to add some acid today possibly as it is...

I'm at the point now where I have to add dry acid every week or so because of my climbing pH, even when there hasn't been a lot of swimming going on lately (not too much rain either). Our TA has been pretty steady around 70. I just lowered pH from 7.7 to 7.5/7.6 the other day. In the early...

Our pH tended to be on the lower side in the beginning of the season, but it has been creeping up. (What is causing it to creep up? We've really only been swimming a few times - have had lots of rain though, so I guess that could be it, the aeration.) pH - 7.7 TA - 80/90 FC: 5 CYA: 40 If...

We strictly use liquid chlorine. We seem to lose about 2 ppm per day. I always test the chlorine around 4:30 pm every day and it's almost always down to 3 from our target of 5 (at least I think it's at 3..read on). Now, the problem is my eyes deceive me sometimes where I can't tell if it's at...

Hi guys :) I posted something to this effect a little while back (along with another issue) but didn't get many responses in terms of this particular question and I'm looking for advice/suggestions. When initially coming on this awesome site, we were using chlorine tablets through our...

Does anyone else's vinyl liner bulge out in areas when raining? We have noticed this before, mostly in the shallow end, and it happened again today. We seem to notice it when we are wasting the pool when it's raining, so I don't know if it's just from the rain alone, or wasting + the rain...

Do you do anything additional or special after swimmers, particularly regarding chlorine if levels seem ok? (This may be a dumb question but searched everywhere for answer and couldn't find it.). Tested FC this morning and was 4. Then tested about 2 hours after swimmers and it was 3, where it...

We are having to replace a lot of water (water fell just about almost at the bottom of the skimmer). When is the best time to test after replacing water is complete, in which I will get the most accurate reading of all categories (biggest concerns are CYA and chlorine, I would think)? An...

We starting using the chlorine tablets basically just the first day we opened the pool and then I came on here and learned that's a terrible thing to do :oops: , so we shut off the chlorinator and have been using strictly liquid chlorine since then, meaning we have only been using liquid...

FC: 4/5 pH: 7.8 TA 120 Last night, our pH was 7.2, with TA at about 80. I used the pool calculator and calculated that I needed 32 ounces of soda ash to increase ph to 7.5 and TA by about 9.1. This morning, I just checked it and our pH is 7.8 and TA 120. I know this seems to still be...

We're doing good with our pool but this question has been on my mind so I thought I'd ask. (We use only liquid chlorine, no tabs). If you test in the evening, your target FC is 5, and your actual FC when you test that evening is 5, do you normally add any chlorine at that time for overnight to...

I have lots to learn about aeration. Only just heard about it from TFP. Is there a dedicated link explaining this process and why it raises pH? Trying to piece it all together. My second question is regarding pH, rain, and aeration. I'm in NJ and were getting hit with some heavy rain and...

I just noticed this and I'm curious as to why there is a difference. I noticed my TF-100 test kit has recommended TA levels for non-salt 100-120, but the recommended levels for TA in Pool School for non-salt (bleach) is 70-90+. Why the difference? Wondering where the best TA range would...

I am just learning about the BBB method and bought some borax to have on hand as our pH is looking a tad low. Before using it, however, I just started researching borax safety in pools and not coming up with a lot of reassurance about it being safe. It sounds like it has not been studied...

Ok, this is my very first post with results. I am using the TF100 kit. I posted previously basically just introducing myself. Again, I am new to this whole thing, so please forgive me ahead of time if I ask stupid questions. I have read the guidelines and all of the articles a few times...

I am somewhat new here. We have an inground pool with sand filter. Last year, we had issues with algae. I was told by many on here that I should invest in a good testing kit. We just had the standard kit and I am now looking for a better kit so this year, if I run into any problems like last...
