I'm going to be closing my pool in the next week or so. I'm in Southern Ontario and thinking of converting to a SWG. It seems from the threads I've read that it becomes more cost effective over time. I do have a couple of questions though:

1. I like to keep my pool between 88 and 92 degrees. This tends to be a higher maintenance zone with regards to chlorine to make sure that algae doesn't start. I find that I need to add 2L of liquid (12%) chlorine to my pool daily to ensure good chlorine levels. Will the temperature that I maintain cause any issues with water quality if I switch to a SWG?

2. I have a RayPak Pool heater and a Hayward Filter with a 1hp constant Hayward pump. I run the pump 24/7. I can't go less than that because my pool is old and was installed by a previous owner. It was poorly installed and the return jets are not positioned well to circulate the water. Keeping it on 24/7 circulates well, but if I reduce it I think I'm going to have massive algae issues (or other water quality issues).

Could anyone advise if anything here will be an issue?

NOTE: My pool is 14x28 Grecian (about 12,000 gallons).
 
You shouldn’t have any issues switching to a SWG for chlorination. When considering what cell to invest in, make sure to size it appropriately for your pool (get a cell that is rated for double the volume of water that you have.) Running 24/7 with a SWG allows you to constantly produce chlorine which is a good thing. It eliminates large swings in FC levels that can happen with manual dosing. I run 24/7 and would’t change it, in fact a lot of members with SWG‘s do the same.

There are systems that allow for liquid chlorine dispensing if you‘d want to got that route. Stenner has systems designed for this purpose, and many DIY systems have been built to do the same. Personally though I’d advocate for a SWG over a liquid tank as a matter of preference and ease of use without jug lugging.
 
Thanks for your input.

I'm thinking of the following equipment:
CircuPool Edge-40 SCG (only $10 more over the Edge-25)
CircuPool TJ-16 "Typhoon" Centrifugal Pre-Filter
CircuPool TOTALBalance PH Control (Acid Free)
Waterco CC150 Trimline Slim Cartridge Filter 150

Total Cost = $2,947

My pool is about 10,000-12,000 gallons and while the Edge-25 produces 2x what I need, I thought since it is only an extra $10, I can just go with the Edge-40. I was reading the larger the capacity, the long it will last for.

Also, I currently have a Hayward sand filter but I want to get rid of it because I often forget to do the backwashes regularly. As well, it seems to leak at different spots. Finally, the water waste with the backwashing. I realize the cartridges have a bit more maintenance (cleaning them out once a month or so), but with the pre-filter, I'm hoping that will go down to twice per season or something like that.

For the PH control, I have a CO2 extinguisher laying around, so I like that. And, I'd prefer that over buying Muriatic acid all the time.

Thoughts??
 
Hopefully others will chime in.

Oversized on the SWG for the price you found is a good thing.

The filter you have spec‘d appears to be the minimum you want for the volume in your pool. It‘s usually recommended to oversize it or go as big as your budget tolerance can. I’d look for the next size up. You’ll reduce cleaning frequency of cleanings and maintenance time. I don‘t have any familiarity with the brand listed so can’t speak to its quality directly.

I can’t speak to the PH control listed. Have only used muriatic in various applications.
 
Dont worry about your temperature. My pool is regularly at 92 degrees. SWG is just fine for that. You may need to check your CYA more often as it degrades at higher temps.

Thanks... The filter says it is rated for 18,000 gallons by itself and 30,000 gallons with the pre-filter that I want to get.

Is that not oversized enough?
 
Regarding the brand, I went to the brand comparison link at discountsaltpool.com (that I found in another thread here) and Circupool has the best warranty listed and it doesn't penalize you for DIY installation which most other brands have (from what I can see).

If anyone else can chime in on the brand, that would be very helpful. Or, similar cost in Canada would be okay too. Circupool is not available in Canada from what I see and I'll have to order from the US to get it.

Jim,

Unless you live in Arizona and have sandstorms, you don't need a "pre-filter".

I can't believe that you run 24/7 with a single speed pump. That must cost a couple of Canadian bucks.. You might want to think of getting a VS pump.

But.. I really just want to know more about your CO2 extinguisher pH control. Can you please pass on the details on how you use it??

Thanks,

Jim R.

I have a lot of "seeds" around from foliage. I figured the pre-filter would help with that. Less about sand/dirt. Does that not work that way??

VS Pump: The reason I haven't switched to a VS pump is because in the past, I've run the manual vacuum (zodiac) constantly and it has reduced the circulation. I have not had the issue since switching to a robot vacuum and keeping the circulation full all the time. I figured a VS pump would cause the same problem.

Here is the link to the PH TotoalBalance unit for using CO2 as the PH balancer: CircuPool TOTALBalance pH Control (Acid-Free)-TBPH

I'd say a SWCG minimum 2 x pool capacity + a vs pump which will be way more efficient then running the single speed pump. You also can use hair nets in the skimmer to catch the seeds and not letting them get any further into the filter system. If your chemistry is correct there's no reason to backwash weekly if the filter is properly sized. There are some of us here that have cartridge filters that get maintained twice a season and that's it.
 
Your yard and surface area dimensions determine the filter size. Gallons is irrelevant as you could have a 10x10 pool that's 100 ft deep for 10k gallons, yet there us only a 100 Sq ft entry point to suck up blowing yard debris / dirt / pollen. That's an extreme example, but you get the point. :)

The larger filter needs to be cleaned less often and is similar to the SWG where going double doesn't cost anywhere near double. Instead it's 20%-30% more for 100% more capacity. The maths work in your favor bigtime and both will pay you back over time.

For the SWG, it's a financial payback. For the filter, it's less maintenance season after season which has a time/effort value that increases with every season. Cartridges can last 10 years with proper care, so divide the upgrade cost by 10 and even an $800 upgrade on the filter equates to $80 a season. If it saves you 3 cleanings a year, that's about $25 each.

When the Cartridges need replacing, they don't cost as much as the whole filter so the second and third go become even cheaper.

VS pumps are another great investment. It will literally pay for itself in electric savings. Mine will save 2X or more it's cost over it's lifespan.
