SWCG or Power Ionizer?

Sparkling clean does not mean that a pool is sanitary. "Frog" may keep algae away but won't kill viruses.

SWCGs are easy but are not economical.

I think Dave's suggestion is a good one. A way you could get around having to check it daily would be to deliberately run a high CYA high chlorine pool. Check out the Best Guess Chlorine Chart in my signature below to learn about the relationship between CYA and needed chlorine levels. For pools with high CYA, sometimes you can get away with adding bleach a couple times a week instead of daily. Just another option for you to think about.

As mentioned above, we don't encourage the use of copper systems, due to problems with staining and green hair. Plus, they are often sold unofficially as sanitizers ("Of course, the EPA won't let us tell you how effective they really are!" Wink, wink!).

If you want a pool that's sanitary, you'll have to use chlorine regularly.

But there are a number of steps you can take to make your pool more forgiving of occasional neglect:

1. High stabilizer + high chlorine pools can go up to a week without additional treatment. You'll need a K2006 testkit and an understanding of the 'Best Guess' page. There's no additional cost, since you need the testkit anyhow.

2. Raising your borate level to 60 ppm or so will make your pool more resistant to algae. Cost is around $50 per 10,000 gallons of pool water, for borax, muriatic acid, and a bottle of Lamotte borate test strips. If you work at it (maybe 4 treat/test cycles) you can accomplish this in 2 - 3 days.

3. Lowering your phosphate level to 200 ppb and keeping it there. Assuming an initial phosphate level of 2 ppm (2,000 ppb) cost will be $20 for phosphate remover and $25 for a phosphate test kit. Allow 1 - 2 weeks to achieve a low enough phosphate level to be effective.

BUT . . . you'll have to go through your regular chemicals and make sure you're not adding phosphate unknowingly. Most stain/scale products contain phosphates, and many chemicals sold by United Chemical do so as well. Pool stores commonly sell phosphate removers AND products adding phosphates! Ongoing expense will depend on how much fill water you have to add, and how much phosphate it contains. City water can contain up to 3 or 4 ppm.

4. Regular use of polyquat algaecide will also increase your pool's resistant to algae. Polyquat is also an effective clarifier, so if you have a sand or cartridge filter, you may see an improvement in water clarity. Cost will be around $25 per month per 10,000 gallons of pool water. Polyquat can be added quickly, and is immediately effective

Please note that if you chlorinate consistently and properly NONE of these steps are needed, unless your pool is one of those mystery pools with recurrent mustard algae.

But each of these steps can be helpful for pool owners who tend to be somewhat inconsistent. And, the cost of cleaning up after a single bad episode of algae will often be more -- in both time and money -- than the cost of ALL of these steps combined.

You can add salt to a pool that does not have a SWCG if it's the "feel" you are after.You just need to add bleach to chlorinate.
