It was a winter of heavy snowfall, a Spring of heavy rainfall…

 

Heavy rains filled our rivers and pools this past few months...

 

Question: What Impact Do Harsh Winters Have On Your Pool Finish?

Answer: It means precipitation has changed your water chemistry and diluted your pool water. This year you will find that your pool water is more corrosive than usual. (e.g. calcium hardness is very low) These things must be corrected at your pool opening; but what is the effect on the pool before it is opened?

A [plaster] pool finish has a high calcium content. Pool water is “hardened” with calcium chloride in order to protect a pool’s finish. This is an important part of the overall balancing required to maintain pool water that is neither corrosive or scaling but water that is just right.

A pool finish can get pretty “beat up” when water is soft (as far as calcium goes). To make matters a bit worse, we are also finding (THIS year) that our pools have a generally low pH and Total Alkalinity. Taken together these factors make for more-than-normal corrosive water. This is one of the primary factors that lead to degredation of finishes while pools are closed.

This year, pools in our area have had about 2-3 feet of new water added from snow and rainfall! Water from snow and rain is not quite like your city or well water. Rain water is very soft and what is in the atmosphere often winds up in your pool.

Key Point: Swimming Pool water will tend to be very soft and corrosive this Spring- more than normal .

Next up: Other pool challenges brought on by dilution from rain water, and how to protect your investment.

Salt/Chrlorine Generators

Salt/ Chlorine generators.

Over the past couple years there has been a lot of buzz about “new” and improved pool water sanitization systems for residential pools.

While Salt/Chlorine generators are  not “new,” the technology has certainly improved since being introduced to the residential pool industry decades ago.

Pictured above- example of a modern salt/chlorine generator- This one manufactured by Pentair Products. Note the diagnostic and status display lights.

We have tested several salt/chlorine generator models and heartily recommend them as an alternative (and upgrade) to the traditional erosion feeder.

A brief review:

1) “The water feels better…”   One of the most common reports I hear is that “…the water feels better!” Salt/chlorine generators produce chlorine from common table salt (NaCl or sodium chloride) dissolved in pool water. The improved “feel” of the water on skin and eyes is largely due to the presence of salt in the water. If you’ve ever used saline solution (e.g. eye drops) it is very much the same effect. 

Salt levels required by these units is about 1/10th the salinity of seawater. Some claim they can taste the salt, others say they cannot. But all say, “…it feels nice…”

2) Eco-friendly:  Another reason to consider a salt/chlorine generator is the fact you are manufacturing your own sanitizer and no longer need to store or handle chlorine tablets on your property. Fact is, with every salt/chlorine generator installed, there will be that much less chlorine transported across our highways by pool service trucks or being manufactured in plants and stored in our communities- that’s a positive contribution to the planet. 

Another reason to feel ecologically responsible: Water with these [low] salt concentrations is not considered hazardous to the environment.

3) Easy to upgrade: The low levels of salt required to run today’s salt/chlorine generator is safe for use with your existing filtration and heating equipment making it pretty easy to install them!

I’ll be talking about other sanitization issues and “hot topics”  in future blogs as the temperatures rise. 

Hope you are enjoying your summer swimming season!
