RE: Salt Water vs Ozone and Quick Spa Question (Follow-Up #4)

posted by: huskyridor on 12.10.2007 at 10:51 pm in Pools & Spas Forum

Ozone is the most AWESOME sanitizer of them all.

However to use it as your only form of disinfecting a full size pool you'll need a commercial/industrial grade Corona Discharge Ozonator.
This will cost multiple 1000 dollar bills, and the need to run your pool on a high speed. You must hit a minimum of 3 turns per day and 4 to 5 are preferred. In addition you'll be utilizing another chemical (sodium bromide) to best activate the ozone. Together they form sort of really badass sanitizing acid that blows away any other form of disinfecting. I don't know how true it is but I've heard it's like 50 times stronger and 5000 times faster than chlorine. This is probably bogus information from the mfg's rep.
I'm no fan of the residential grade ozone generators because the manufacturer doesn't point out the entire truth of the system, how it functions in amount of ozone generated, and how it can only be used a a support sanitizer.
My suggestion is to go with the SWG or chlorinated tablets as the primary and add on the Ozonator as a secondary if they choose to.

Don't be fooled about what folks may say about the Ozone generators. They're ABSOLUTELY THE BEST, especially when utilized with Sodium Bromide. Those who bellyache about them just got sucked up by some hype and had a totally mis-spec'd system for their application.

See ya,
Kelly

Good bye, I'm out of here

Folks, it's been nice meeting you folks and chatting about pools However, it has become time for me to move on from this forum. It seems that the management has decided that some of my posts are unworthy, and had to be deleted. I've been posting in various internet forums for over 20 years (no, that's not a mistake), and never had so much as warning. I've also been an admin and moderator on other special interest forums, and so I know a bit about managing forums such as this. So you can imagine my surprise to have posts deemed unworthy and to have been deleted. That, and the recent JBlair Logo thread that was deleted are unacceptable to me.

Now this is a privately run community, and it is perfectly legit for the owners to set rules. I have no problem with that. My problem is the random deletion of threads and posts with absolutely no due process or public explanation. With those actions, the management is changing the information that you see to what they feel is best for you. It's dishonest, and you're not getting the full advantage of an online community. You're getting filtered information.

Frankly, I'm surprised at the popularity of this site. The participants here (you folks) are wonderful, and it's the ONLY reason I've participated here. The BB software here is absolutely the worst forum software on the internet. It requires knowledge of HTTP just to embed a picture in your post. There's no way to go back and edit your post to fix typos once you hit submit. And of course, there's no spell check, emoticons, decent search engine, or any of the other features that are standard on every other internet forum in the world.

Thus, I've decided to "vote with my feet" and move on to a different pool forum. I'll be at the poolcenter.com.

Here's a link PoolCenter Pool Forum. My handle on that site is "AZ Pool Boy". I hope that some of you good folks will visit me there. Or if there are any other good pool forums out here that you may know of, I'm open to those as well.

Good swimming and best regards!

Kelly,
I have read many contributions you have given to the general public on this board. You deservedly have a great following and your thoughts are usually right on. You have been a great help to many on this board.

I just have to take issue with your above post for several reasons.

You obviously do not live in California nor do you write your check every month to SDG&E. If you did you would not have posted what you just did.

I honestly do not care what eann buys as far as equipment - the reason is I think I know who the builder is (there are very few builders in San Diego that use Jandy) and if it is who I think it is I do not want him buying our equipment for several reasons. Pentair is far better off letting Jandy have that account.

My issue with your post is how could you possibly recommend a 2 speed? Anybodys including Pentair WhisperFlo, on the pool eann described. The bottom line a pool with 2 skimmers and a salt chlorinator at low speed is never going to work properly for long - You cannot get enough flow. The filter dirt will shut down that flow so quick that the homeowner will be forced to go to high speed - losing any energy savings. Pumps do not even prime well at low speed - almost all have to primed at high speed for several minutes - again losing energy savings because they have to prime at high speed.. Never mind the switch used in 2 speed motors that shift speeds from high to low is barely adequate as best - it will not last long with all the switching. With 2 speeds you have no choices in speeds other than high and low.

Secondly I think your pricing is way out of whack. Eann was asked to use the IntelliFlo 4x160. I think you are in the pool business and can easily see your cost difference between a 2 HP 2 speed and a 4x160 - see PWP flyer.

Your cost is not 1300 bones !!
Your cost is 718 bones !! If you are being quoted 1300 bones you are being taken advantage of and are not doing your pricing homework.
Your cost on a Jandy 2.5 HP Stealth P/N SHPM2.5-2 speed) should be about 240.00 less than a 4x160.

You also do not have any concept of what people pay in San Diego for energy. I am attaching below SDG&E room by room guide on energy costs - go to page 4 and look at a 2HP. These people pay between .28 cents to .47 a kilowatt for energy to run a pump per hour. Lets split the difference and say the average is .37 cents an hour. For 8 hours a day times 30 days for this one pump these people pay 89.00 a month minimum for one pump. Most of these pools have more than one pump.

Finally and I have said this many times already on this board homeowners are getting this way before the pool professionals - because they foot the bill. The train has left the station on variable speed and is not the future but is the now.

Lastly the savings using a 4x160 is easily 50% for several reasons: rare earth magnets Finally and I have said this many times already on this board homeowners are getting this way before the pool professionals - because they foot the bill. The train has left the station on variable speed and is not the future but the now.

Lastly the savings using a 4x160 is easily 50% for several reasons: magnets in the pump reducing AMP draw, versatility in RPM's (305 speeds verse 2 speeds) and finally a product that is set to the speed that is needed to do the job and not be wasteful- not like the past and guess present in certain instances where the pump was plunked in and people had to live with it because that is what it is. Noise level, which again are important to people in California and elsewhere due to the lot sizes are tremendously quieter.

Again on 2 speeds: example at 40 GPM's at low you will use about 300 watts - a 4x160 will use about 180 watts - thats 40% savings on low speed alone.

Again on 2 speeds: example at 40 GPM's at low you will use about 300 watts - a 4x160 will use about 180 watts - thats 40% savings on low speed alone.

Kelly not mad just trying to keep the facts between the ditches.

RE: Salt Water pools (Follow-Up #15)

posted by: hotwater9 on 07.26.2007 at 08:14 pm in Pools & Spas Forum

Well, we are slowly in the midst of building a salt water pool and will have a natural stone water line and waterfall with travertine coping. We did go with natural looking tile in place of real stone for the hottub and part of the waterline but are not willing give in to not having a SWG. Wish us luck!

NOTES:

I like this stone work
