Ok I think I see our problem here, or at least part of it the Spinlab will only read FC up to 15 ppm WaterLink Spin Lab - 3576 - Pool and Spa - LaMotte so the pool store test is likely at the limit of there test and off the scale high. Your FC may be much higher than we thought, but before...

James W. Thanks for that thought, it never occurred to me that someone might have added Bromine to a pool that was running on an SWG, although I guess anything is possible.

I did check and mine is a 20 inch 12 amp, 12 amps at 120V is about the expected draw of a 1HP electric motor, maybe 1.25HP. As a rule of thumb for things like air compressors, etc. you need twice the HP when running with a gasoline motor vs an electric motor. Either way mine has worked for...

Sounds like an interesting project you have, unfortunately the photos are not showing up :(

Ok, something is wrong here There are only a handful of possibilities: 1, The Hydrogen Peroxide was really really old (you might want to check for expiration dates on those bottles) 2, You still have something adding Chlorine to your pool, if it is not manual addition , maybe your SWG is not...

I think worrisome point here is that you said you have had to SLAM 3 times this summer, why? Many members on here go years between having to SLAM, and then it is usually caused by extreme weather, equipment failure, etc.

I agree 100% with Mr Bruce, many of us here are self described pool snobs and would not consider getting into most pool, particularly ones at hotels, resorts, etc. that are often maintained by people that don't know what they are doing and don't really care.

I have always found the battery compatibility game to be a losing game, the companies change up battery styles every couple of years then charge more for a replacement battery than the cost of the tool

I bought a plug in electric push mower to get into those spaces the big riding mower will not fit around the house, it works great but does need a good quality 12 or 14 gauge power cord, not one of those cheap 16 gauge 100 ft cords. Mine is a Greenworks brand, bought from Amazon, I think the...

Sorry I thought I replied to this already, maybe my post did not go through, Anyway I said you should do an OCLT any time you have unexplained chlorine consumption.

Personally I think the best thing you can do for these customers is sell them on a liquid chlorine injection pump that will add a fixed amount of Chlorine each day, then you can adjust the FC manually and tweak the output settings on the pump on your weekly visits. This would stop the roller...

This equipment does look to be at least a few years old, I am not sure what your question is otherwise.

Just remember it is usually better to under shoot than to overshoot when making these sorts of adjustments

That sounds like a good plan if the pool store numbers were right with an FC of 18, it will take probably all of that hydrogen peroxide to get you down to levels that show on the chart for the OTO test +/- half a gallon or so.

There are several other potentially good brands out there, but most are bit players, then there are a lot of fly by night change the name of the company every year to get away from the bad PR brands. Also avoid the Costco spa of the year which is often made by one of the big players, the...

It takes chlorine considerable time to break down those foaming agents

The brands I would consider are Hot Spring, Jacuzzi, Dimension One and Bullfrog, of those Bullfrog is unique in the fact they have modular interchaneable backpacks which all a great deal of customization now and later. If looking to save money you might consider used / refurbished hot...

Skimmer position should be based on prevailing wind patterns, not so much size of pool. In my region we tend to get wind from the south for about 6 months and then wind from the northwest for about 6 months

On the topic of concrete sealers, not all are created equal, in fact they are not even in the same ballpark.

Matt, it does sound like you have had a bad experience with actuators. I guess I should be thankful I only have one (Hayward brand actuator), it is connected to my solar controller and typically switches positions multiple times per day year round (operating in freeze protection mode in the...

You might have had some organic contamination, the FC would react with that and form CC. as to the bottle with no expiration date, you can contact Taylor with the lot number and they can tell you if it is expired. Ike p.s. the CC reading may also have been from tap water if you rinsed out...

see my ps I am going to be away from the house a bit here too, but will try to check back in when I can

If it were mine I would be making the rounds of the dollar stores to get hydrogen peroxide and getting the FC down. Once the FC is below 10 ppm which will be a sort of pale amber yellow on your OTO test kit. You can retest the pH and adjust from there. I just use liquid chlorine (I have an...

I am not sure what is in proshock, but the tablets will have trichlor which will add both chlorine and CYA, so will the Dichlor. (having some CYA is good as it makes the chlorine less harsh). Around here we generally suggest 20-30 ppm CYA for indoor pools, which is what I typically run in...

Ah, pool store testing, yet another reason to believe it is not worth the paper it is printed on, let me guess they use test strips with an automatic reader? Let me ask another question, since disconnecting your SWG have you used any Chlorine products? if so what type? Ike p.s. I guess I...

Ok you have the OTO Chlorine test then, which is good in this case as the common DPD (shades of pink) chlorine test can get bleached out at high FC levels. How did you measure 2 ppm CYA, the common CYA turbidity test only reads down to 20 ppm Ike p.s. it looks like you are still updating your...

Yes,and no, the problem is the common pH test is invalid at FC levels over 10 ppm, so you need to get your FC down before adjusting the pH. You can do this one of two ways, you can use common hydrogen peroxide to lower FC or you can use a granular chlorine remover from the pool store. If you...

Sorry about your troubles, but at least it seems like a nice day for your head banging, it could be worse.

Ditch the pool store and get your own quality test kit, I suggest the TF-100, link in my signature. Step 2 post your pool details in your signature and maybe a couple of photos of the pool and the equipment you have if you are not sure and we can help get things sorted out. Also you may want...

Some people use the OTO test during the week and the more costly and more accurate FAS-DPD test once per week, others like myself almost exclusively use the FAS-DPD, although the OTO is good to have around as a sanity test. The OTO reagents are very cheap (refills of OTO solution are only about...
