Lershac thanks for the reply. I wish I would have looked into this earlier but they are doing the coping on monday.

[quote="JamesW"]I would upgrade the rebar to #4 and the wall and floor thickness to 8 inches.
The Clean and Clear (Plus) 420 is a good choice.
Pentair rainbow 320 automatic chlorine/bromine feeder should be the Off-line model vs. the In-Line model.
Each light should be on its own separate switch to allow for independent operation.
You might want to consider the IntelliTouch vs. the EasyTouch automation. Intellitouch will be more capable.
You might want to consider adding some water features, such as lighted laminars or waterfalls.
I would want two separate, independent return lines going to the pool

James I forgot to ask why the off-line rainbow feeder vs the online type? Steve

The reason for the off-line model is that if the in-line model is put before the salt cell, then trichlor feeds into the cell, which is not good. If it is put after the cell, then the cell output feeds into the tab feeder, which is also not good. For one thing, hydrogen gas could build up in the feeder, which could be explosive.

Using the off-line model will allow the feeder to pick up water before the cell and return it after the cell. I would only use one at a time. If you wanted to use the tab feeder, then you should turn off the salt cell until the tab feeder was clear of all tabs and then switch back to the salt cell.

I have never like on-line models. Since you are getting the IntelliChlor, the trichlor feeder is mostly redundant. It does have some minor value because there are a few times that trichlor can be useful. For the first 30 days, the salt system will not be used, and trichlor can be used to add chlorine and cyanuric acid and lower the pH.

After 30 days, the value is pretty minor. It can be used to lower the pH and add cyanuric acid, but it's not necessary. Most people don't bother with a tab feeder when they have a salt system. I think that it can have some value, but it can also create unnecessary complexity.

Are you going to use a salt system, or go with liquid chlorine?

[edit]I didn't see a salt system in your signature, but I see one in your build thread. Are you concerned about the travertine holding up over time with the salt water that will splash out onto the deck?[end edit]

Maybe I just won't bother with it then James. I was thinking it would be nice in the summer if the salt system was having trouble keeping up. Im not even sure that will happen or not.

Not a bit. I have seen many travertine and natural stone decks with salt water pools and very rarely seen any issue. I specifically hunted down some over 10 years old, found one that was 20. No issues. And if there is, I can afford to have it replaced.

sorry for the thread hijack, it was unintentional.

Yes, I didn't intend to hijack the thread. I thought it was relevant because the poster had originally considered travertine, and I said that I didn't think that it was the best choice for use with a salt pool. Travertinemart.com claims that it's not a problem, but I don't necessarily agree.

Which is fine for selling the stone. However, they are not willing to back it up in the form of any type of warranty or guaranty.
I think that there are multiple issues that affect the suitability of travertine around a salt pool.
1) The quality of the travertine. There can be a huge difference between the quality levels of natural stone.
2) The use of a good sealer, such as DuPont StoneTech Professional Salt Water Resistant Sealer
3) How much total water gets splashed on the deck. Some pools get very little use and water rarely gets splashed on the deck.
4) The finish of the surface. If the finish is already rough, then minor damage to the stone will tend to blend in and not be noticeable.

I think that the customer should have as much information as possible to make an informed choice. Ultimately, the customer will have to weigh all of the factors and decide which option is best for them. Of course, being able to afford to replace it, if necessary, is one important factor to consider.

Wow, have an axe to grind against travertine much?

I like travertine and limestone. I just don't think that either is a good choice to use around a salt pool that will get a lot of use where a lot of water will splash on the deck. Many builders won't warranty travertine or limestone with a salt system and require the customer to sign a waiver. And, many stone suppliers also will not warranty travertine when used around a salt pool.

I think that the risk is legitimate, and that it would be irresponsible not to advise the customer about the risk.
