My SWG is not producing chlorine and I just realized my "no flow" light is on". I'm assuming my flow switch needs replacing, which I've done one before (maybe 3 yrs ago) so I ordered one today. If this light is on, am I correct to think my SWG won't produce chlorine? Or am I dealing with 2...

We're going away for 3 weeks and our hot tub won't be maintained. We can't drain it as our temps are below freezing here, so we need to keep some warm water circulating throught the plumbing to prevent damage. How low would you say is acceptable to keep the water temp?? And would you dump a...

I use a pH meter to test, and recently purchased a new meter. For some reason, I was doubting the new meter and decided to double check with my old meter. I first calibrated both. Everything looked good, both were reading very similar. Today, I checked again with both and they're reading...

This morning we woke up to our pool water being a bit cloudy. I had my hubby test the FC and CC. The FC was 5 and the CC was 0. I couldn't deal with the situation right away because I was at work, so I had him shock the pool. He raised the FC from 5 to target of 20 (we didn't actually test...

What are the consequences of having high phosphate in my pool water?? Once a year I have to take my pool water for testing at the pool store (I know, frowned upon here, but I do it to get borates and salt levels at the beginning of the season), and my phospate level is 2159. Apparently it's...

We’re in the process of opening our pool, but it’s really not swimming weather yet. I’m planning on doing a SLAM, but hoping not to heat the pool until the weather warms up a bit. Is there a minimum water temperature for SLAMing? Our pool temp is sitting around 55 degrees right now.

Has anyone found anywhere in Canada (specifically the GTA I guess) to buy boric acid at a decent price? I currently buy Bioguard Optimizer Plus, but it's powder and not the granualar I would like to have and it's also $80 for 9kg, so quite pricey. I have looked into doing the borax/muriatic...

So, I neglected my hot tub for a few days (ok maybe closer to a week), I was only using the test strips and adding chlorine just before using. Now today, I decide to test properly and my FC was at 0 and CC was 7!! Ooops. At 1050 FC 0 CC 7 pH 8.0 CYA 40 12 oz of bleach added (to achieve shock...

Has anyone tried Spa Marvel water treatment? Is it as good as all the hype?? https://spamarvel.com/spa-marvel-water-treatment-and-conditioner/

Hi, our new (and first) hot tub is being installed tomorrow. We have the option of using chlorine or bromine and I'm not sure what's best for us. As an aside, we use the TFP method for our salt water pool and I have the TF-100 kit for testing. Any recommendations on what we should go with??

I’ve been having issues keeping my FC up. Here’s a little history: May 27th @0830 FC 7 - SWG at 35% (4.5kg of borates added - pool was emptied last season and we lost all our borates) -3 days of no swimming, pool cover stayed on, cold out June 1st @ 0830 FC 2 - water looks cloudy in deep end...

Is it OK to SLAM with the pool cover on? It still gets quite cold here at night and I'm hoping not to lose to much heat. Also, can I let the automatic vacuum run during the the SLAM? And lastly, does anyone run their automatic vacuum at night, with the cover on? I'm not sure if the weight...

Ughh, we have a small leak in our pool pump. The cement slab under the pump is wet all the time, the leak is small, but it’s there. We can’t tell exactly where it’s coming from, but it’s under the pump somewhere and not at one of the pipes. We have the Hayward Super Pump Variable speed. Any...

When we open our pool in the spring, I always feel a bit like a newbie when it comes to testing and balancing the water. Our winters are long in Canada, it's been awhile!! Here are the results of my first water analysis FC 8 CC 0 CH 275 TA 90 CYA 40 pH 7.8 About the only thing I think I need...

We need to replace a light bulb in our pool this year. We have lights that change colors. A replacement bulb at a pool supply store is over $400. I’m completely shocked!! Is there any other options out there I should be looking for? Thanks!

Our pool is still closed and winterized at this point. We’ll be opening it next weekend. Is there any reason I can’t start topping up the water before we take the cover off? I was hoping to have it filled by the time my husband takes the cover off to save some time on opening day. Also, it’s...

Any Canadians know if there are any restrictions on importing the TF 100 kit into Canada? I know they don’t ship to Canada, so I usually just have it shipped to a US address and pick up, but we’re unable to cross the border at this time. I want to use a parcel pick up service that’s still...

We're in the process of closing our pool for the first time ourselves. We have a lock in winter pool cover, but we can’t figure out how to use it. (The one that somehow clips in under the coping) I’ve googled and Youtube searched like crazy, but can’t find anything. Can anyone here help...

We’re going to attempt to close our pool ourselves for the first time. We are located in Ontario, therefore have quite harsh winters. I’ve been reading a lot about closing the pool on the forums, but I can’t find anything about a pool with a waterfall. Any special precautions we need to take...

I've been having to turn my SWG up recently to maintain my FC levels (from 30% to 50%). My CC is 0 for the most part, but I have had a reading of 0.5, maybe twice out of the 7 times I've tested in last 1.5 weeks. I decided to shock my pool tonight. I don't have time to start a SLAM, as we're...

This mornings test results.... FC 7 CC 0 pH 7.7 TA 150 CYA 80 Do I have to worry about the high TA?? I will add some muriatic acid to bring the pH down, but otherwise, anything else I need to do? Thanks!

Ughhh, I did it.....despite the fact that I thought I was being careful and slowly raising my CYA over the last week, I overshot. It's 90, my goal was to get it to 70-80. What happens when your CYA is this high? Is it absolutely necessary to lower it? I know the only way to lower it is by...

Hi, these are my results for my first testing of the season: FC 2.5 CC 0 CH 200 TA 140 pH 7.5 CYA 50 temp 72 My SWG isn't working ("no flow" light on - I'm working on fixing that), so I need to manually add chlorine. I'll put in what the Pool Math calculator suggested to reach my target...

We had liner issues and had to completely empty our pool to get it fixed. I'm now in process of refilling it. Where do I start once it's filled?? This will be my 3rd summer using the TFP method, but because our summers are so short around here (4 mths or so), when I open up the pool again, I...

Ok, so I know I’m going to get my hand slapped, but this is bugging me enough that I have to ask. I do all my own testing and follow the TFP method religiously. The only thing I can’t test at home is borates, so I brought a sample in to my local pool store this morning to get the level. Of...

Is it ok to preform an overnight FC loss test after a pool party that saw 12+ kids swimming for hours on end? Or should I wait until tomorrow to do it? My usually crystal clear water looks a bit cloudy tonight (I can still see the bottom of my pool, but it’s not a clear as usual).

I need to increase my CYA (currently 40, aiming for 70-80), but before I run out and buy something, I'm trying to use up what I received in my new pool purchase bundle. Does anyone have any experience using Salt One from IPG pool products? There is not a list of ingredients on the packaging...

When I'm running my pump normally, with the skimmer line open, I don't see any turbulent flow in the basket area of the pump. when I open the suction line, still no turbulent flow, but when I hook up my automatic pool vacuum and turn the skimmer suction off and run only the vacuum suction line...

I finally got my pool open today after a looonnng Canadian winter and I'm rusty on the chemistry portion of all this. I followed the TFP to a T last year and had beautiful sparkling water, but I need a little guidance to get started again. These are my results today.... pH 8.6 FC 15 CC 0 TA...

I'm about 1 week post SLAM and finally by FC is low enough to do a complete test. Here are my #'s this morning FC 10 CC 0 TA 100 CH 200 CYA 60 pH 7.5 So, my issue is, pre SLAM, my pH was 7.4. During the entire SLAM process (about 6 days) we ran our waterfall 24/7. We have since been running...
