I "got off the pot" and ordered the Universal40. By the time I was done with shipping and accessories, I was over what I wanted to spend on the Edge. Shipping was $19.19 and apparently the $1 upgrade offer on the other units went to $10 today as well. I was at close to $800 with the dummy cell, cleaning stand and shipping with the Universal 40 as it is. I think it's the correct choice in my specific application and case.

I will do a little analysis on this unit when I get it and I will offer what I find to the TFP Circupool database. I suspect it will be a lot like a Hayward with the T-cells...

Now to get all the work done I need to do this weekend so I can install it next weekend. I do have a functional K-1766. I'll never buy online again unless it is from tftestkits, I actually got a kit with a broken box (which I melted back together) and R-600-A OTO instead on R-630-A Chromate Indicator and the seller just dropped off the face of the earth when I wrote them. I ordered a R-630-C off of Amazon and both are now okay with a far enough our expiration date, but for that price I could have bought it at a Leslie's. I got pool stored from a store in Utah! (I added it to another order at the time.) I guess I'll be doing a lot of OTO tests in the next year to use it up! :) It will be interesting to see what the salt level is before I add water softener salt to the pool... and after 6 months of liquid chlorine.

But this analysis of these units has actually been fun. I suppose that and the control units on a VS Pump are really the only high tech stuff with pools. Maybe solar heat later.. but I think next year.

Cool, now you get to start adding salt :) You don't realize how much salt your adding until you put 6-40 pd bags in your buggy and it's hard to roll! Start adding bags now while it's being shipped
Just a reminder don't buy clorox salt :)

I just bought replacement solutions for my 1766..It was telling me my salt was 3800 now saying less then 3000 so I don't know what to believe..The test strips show 2400 consistently.
They haven't expired, be interesting to see if the new regiment are any different and if so I will add more salt
 
The kit with the bypass cell has strips too.. so it will be an interesting comparison there too.. Go with 2 bars..a little more is always better... :)

I do need to bring CYA up in the meantime as well. I'm at 40 currently... The plan is to try to install it next weekend..

It would be nice if we could get a tiny bit more technical information out of them, I can't see it doing anything but helping them sell cells.

You are talking with sales and marketing people. They give you whatever answer helps make the sale.

Unless you are a Pentair, Hayward or Jandy that may do their own designs if you wanted to create a business selling SWG's you a e not going to design your own. You take a trip to China and visit the factories who build these cells. The will customize the shell and graphics and some of the software for your branding. The engineers are in China connected with the manufacturing plants.

The technique of varying volts and amps for generation % we have seen in SWGs sold in Australia and other countries. It is different then the time based technique used by the American SWG manufacturers.

So if you want to talk to the engineers designing these cells you need to find then in the design labs in China.
 
Yeah, and that is too bad. I do know in Australia by law there they need gas traps in their SWG designs.... and I haven't seen any in US units...

When I was a kid I used to electrolyze water to make Hydrogen Gas and Oxygen. I had some fun with that for awhile until I found Calcium Carbide later on as a teenager... :) But it's not rocket science, I agree. It'll still be a very nice addition to the "odyssey" regardless.

I am working from home today and over lunch I tested salt (and everything else with the TF-100) with the K-1766. I was rather surprised that I have 800 PPM salt already in the pool... I'll double and triple check that but... wow... I wish my pH would come up a little from dropping TA. I suspect I might have to do some Borates before it's all said and done unless the cell does raise pH as much as people says it does..

By the way, for the record I *like* the K-1766. No ambiguity at all in that test.....It's kind of bada-- actually....

My guess is they all have parts made in China.
My thought is Circupool designed them here I Am getting help desk staff probably.

You have to remember that CircuPool's cell warranty is Pro-rated for their residential customers. You have dig hard on their site to find it too, but it's there.

For the Core series:

Year One - No charge for parts. Year Two - No charge for parts Year Three - Parts supplied at 40% of base price. Year Four - Parts supplied at 60% of base price. Year Five - Parts supplied at 80% of base price. Year Six - Parts supplied at 80% of base price. Year Seven - Parts supplied at 80% of base price. Year Eight - Parts supplied at 80% of base price.

For the Edge Series:

Same as above except it's only a seven year warranty.

So essentially after year 2 you are getting a 60% discount in year 3 , a 40% discount in year 4, and a 20% discount in year 5-8. Hopefully assuming they don't change the base price (meaning that it's the price you pay, not the MSRP).

I hope I never need it..But my 1 month old Hayward heater quit and when I called Hayward they said because a pool company didn't install it they would send a guy out for $125 even though I told them the control board was bad. and they said they may not cover it, even though it was a known issue!
Amazon would have me return it but a HUGE pain
I just bought one myself for around the same price and replaced it in 10 minutes

but I look at warranties like Bonuses, great if you get them but don't hold your breath
 
My hunch is the plates are purchased here in the United States and shipped to China. CircuPool (DSP) can import them back into the United States in completed cells without having to pay full tariffs. Everything else is made in China. You will have to take the manufacturer's word that 10,000 rated hours is really 10,000 hrs because how the heck are you going to verify this? It's like buying diamonds. You never really know do you?

I just double checked and my salt is 2800. My drops didn't expire but just to be safe bought new ones from TFTESTKITS and got the same results.

I am positive it was higher 6 weeks but it seems temperature effects the results. I do remember the solution was clumping together.
I am also realizing I have closer to a 25K pool then the 18K I thought at first. Edge40 isn't complaining and seems to be happy but I will add 3 more bags..Just hate to get out right now.

Homedepot will deliver but have a $45 min and I don't need 6 bags!
 
Well I was thinking of picking up a couple of boxes of Borax today, but then I quickly realized that it's another thing that is useless for most people that is being hoarded. So I guess I am going to try some major aeration the next few days. I still want to bring TA down further but CSI is at -0.41 now so until I get pH back up a bit... No more acid. Playing with pool math more than I ever had-- I was surprised by the salt addition in pool math lowering CSI in the calculation. It was also eye opening how much salt is added by sodium hypochlorite. I still am having the mental block of 800 PPM already being in the pool since it was built in September but.. I guess it's possible.

But I did get the stuff to finish up the sun shade for all of the the equipment, and... IMG_20200418_182013242.jpg
Diamond Crystal from Home Despot $8 and Morton $6 from a different Walmart that was just as dystopian as the last time/one I went there... But they had plenty of Liquid Chlorine. I also am going to dip into probably two bags of my existing water softener stash (briquettes) at $5 ea... Those can dissolve longer...

By the way that is the same type of fencing that I built on the other side of the house for the dogs when the pool was being built. That is going to be one wall of the sunshade, there is another going in the other side of the equipment pad facing the pool. Under the fence will be a few pieces of galvanized roofing below the fence line. It will look just like a little piece of fence to hide the equipment which isn't uncommon here. This will hide it from the HOA and neighbors.

I went to Walmart yesterday and add 2 more bags and got mine up to 3400..Yea it's kind of depressing seeing Walmart with just a few folks..I went at 6pm to avoid any crowds and did wear my mouth cover they gave us at work to be safe. Would have had it delivered but the $6 became $16 online and seems wasteful to spend $32 for $12 of salt plus needed to get out of this house arrest :)

Haha, I know where you’re coming from. I definitely am good at over analyzing.

I think the SJ-55 is way too big for your pool. It would work, but I’m not sure there would really be any benefit to going that big. Obviously there is something to be said for getting a larger unit than you need so that it doesn’t have to work as hard which should make it last longer, but I think that just having chlorinated water passing over the plates 24/7 for years will start to affect the coating on the plates and eventually they will wear out and need to be replaced anyway.

Also, I’m not entirely certain that dollars per pounds per day is really the best metric to be looking at. The different series have very different cell lifetimes and I think you need to try factor that in as well. I’ve added to your chart below:

SJ-55 $820 2.3 lbs/day (5 yr) 10500 hr -- $356.52 per lb/day - .096 lb/hr - 1006 lb over the cell life - $0.81/lb
RJ-30 Plus $870 1.5 lbs/day (7 yr) 15000 hr -- $580.00 per lb/day - .062 lb/hr - 938 lb over the cell life - $0.92/lb
Core-35 $930 1.4 lbs/day (8 yr) -- $664.29 per lb/day - .058 lb/hr - 875 lb over the cell life - $1.06/lb
Universal-40 $740 2.0 lbs/day (4 yr) 10000 hr -- $369.50 per lb/day - .083 lb/hr - 833 lb over the cell life - $0.88/lb
Edge-40 $840 1.7 lbs/day (7 yr) -- $494.12 per lb/day - .071 lb/hr - 1062 lb over the cell life - $0.79/lb
SJ-40 $720 1.6 lbs/day (5 yr) 10500 hr -- $450.00 per lb/day - .067 lb/hr - 700 lb over the cell life - $1.03/lb

I figured out how many pounds per hour each cell would make, then multiplied out to figure out how many pounds it will make over the life of the cell, then divided the cost by the lifetime production number to get a cost per lb of chlorine gas produced over the rated life of the cell.

Note that for some reason circupool doesn’t publish cell lifetime ratings for the core and the edge. But based on the fact that their warranties were similar to the RJ series I used the same 15000 hr number for the edge and the core.

hey Brett, I stumbled upon this thread while researching for a new SWG and found this interesting cost table. is this still the best guesses these days in terms of cost comparison relatively? I know the SWG prices all went up.
@Rattus Suffocatus how do you like your Universal 40 so far? what is the lowest GPM/RPM you could run it, and what speed/duration are you running it for your pool? any regrets or if you were to do it again, would you pick something else?
