Mystery #one Salt h2o units corrode the pool gear.
The Facts – The salt by itself has issues of attacking the cement in the plaster and deck elements. This is a somewhat sluggish process when the salt concentrations are lower. The salt also can eliminate any landscaping in or all over the pool as properly as in the backwash location.
If the sodium hypochlorite concentrations are far too large, the corrosion is induced by the chlorine becoming produced by the electrolytic mobile. Chlorine can bleach the take a look at reagents, providing you a “bogus adverse”, and persons can grossly about-chlorinate their pool harming gear, the pool surface, lights fixtures, and ladders. Around time the salt will attack any location the h2o evaporates at.
A prevalent problem is corrosion at the ladder. The deck anchors are usually forged aluminum and the ladder really should be stainless steel. The salt h2o will corrode the anchors additional time and a “basic safety function” will be pending.
Consumers really should be mindful that if you have salt h2o above 2800 ppm, (frequently 4000 to 5000 ppm), you will have to have to reseal your coping every single 12 months, particularly if it is a porous stone like limestone or travertine. Normally, the salt will dry and commence to etch the coping. Other than sealing the stone, it is also a good idea and an extra precaution to hose down the coping at the conclusion of any swim day with contemporary h2o. Whilst the salt h2o in the pool may well not be corrosive at concentrations of 3000-3500 ppm, when that h2o hits the coping and evaporates, it leaves pure salt guiding. The pure salt is corrosive and is the most important bring about of the corroding coping. Most autocover producers now void their observe warranty if a salt method is applied.
Some pool builders are now refusing to establish any salt h2o swimming pools with cream limestone or taupe coping. Any shopper that wants either coping for a salt h2o rock or gunnite pool have to usually sign a release variety. Pool builders have mentioned that they have experienced to substitute a significant amount of money of both of those these kinds of coping this earlier 12 months. Cantilever models simply just disappear as the stone dissolves absent.
Mystery #two Salt h2o units have to have chemicals just about every single 7 days.
The clear weekly use of muriatic acid is combined with the not so clear have to have to use cyanuric acid to ensure your salt chlorine generator can accomplish one-3 ppm chlorine residual in your pool. Considering the fact that salt h2o swimming pools develop chlorine, the sanitizing success of the method is impacted by alterations in temperature, bather load, daylight and rainfall. CYANIDE based, the CYANURIC acid is euphemistically referred to as conditioner or stabilizer and have to be managed amongst 35 and eighty five ppm. Stabilized concentrations about 100 are harmful to small children, animals, more mature swimmers, the pool by itself and of system the natural environment.
Occasional algaecide, clarifier, stain and scale handle and shock will be necessary with a salt chlorine pool (probably somewhat more than a stabilized “puck” pool) and only the dealing with of the reliable chlorine is averted. Various other sanitation products will cut overall chemical use, a salt method may well not.
Mystery #3 Salt h2o units have to have mobile substitution every single two to 3 years at a cost of $five hundred-$800.
With about 40 producers in the salt h2o generator business enterprise the mobile warranty ranges from one to 3 years and the substitution expenditures are from $five hundred self-installed to $800 installed by a supplier. Assuming the operator gets to the fourth 12 months with the mobile, salt can be one of the most pricey solutions to sanitize the pool. If the mobile does not make it through the third 12 months, salt becomes the most pricey method in conditions of operating cost.
Mystery #four You have to fear about the pH with a salt method and do normal upkeep or you will ruin the pool and have zero recourse.
The Actuality – When the pH and alkalinity get out of equilibrium, the chlorine is significantly significantly less powerful. The pH really should be seven.four-seven.six. Chlorinating with a salt h2o chlorinator is very similar to chlorinating with liquid chlorine– they both of those have a large pH (eleven.seven). 1 prevalent problem is that homeowners are inclined not to take a look at their pools’ pH and alkalinity ample. However, far too many builders and vendors market these units as a “set it and forget it” resolution. Most persons with salt units will operate their pH from seven.eight-eight.. This is poor for two causes: one) the pool is in a scaling method, and two) the chlorine is locked up by the basisity of the greater pH. It is greatest to operate amongst seven.four-seven.six when applying chlorine. Absence of pH management can ruin the mobile in significantly less than 90 times, scaling up the swimming pool as properly as the mobile. “Improper chemical use” will void any warranty, a method employed by portable spa producers on delaminated shells and first 12 months heater failure.
Mystery #5 Salt units are more harmful to human health and fitness than conventional chlorine, bromine or bioguanide chemicals.
With a salt method your pores and skin will take up sodium, salt, AND chlorine, as opposed to just the halogen with a chemical sanitizer this sort of as chlorine or bromine. Sodium absorption through the pores and skin has lengthy been recognised to present health and fitness threats at concentrations significantly down below the 3000-5000 ppm concentrations salt chlorine turbines have to have. For nearly 20 years persons with large blood stress, stroke heritage or other circulatory method issues have been requested to stop applying their h2o softeners (at 200-four hundred ppm sodium in the h2o for just ten minutes in the shower) to stay away from the coronary heart mortality threats. The chlorine stage and pores and skin absorption of the chlorine is nonetheless based on the very same one-3 ppm chlorine residuals discovered, dioxin types (as do chloramines) and the backwash h2o is made up of 3000 ppm or more chlorides.
Mystery #six Salt units are harming to the natural environment and have been banned on all swimming pools in spots this sort of as Los Angeles County.
Even though the “Ban the Brine” motion may well have not picked up significantly steam in latest years, specific counties banning chloride discharge this sort of as Livingston County, Michigan or certain bans on salt h2o chlorine turbines in Los Angeles County, California have gotten regional consideration. These present Los Angeles location salt h2o turbines when the ordinance was passed are NOT “grandfathered” in.
Mystery #seven 1 dimensions does not suit all and salt turbines use both of those large voltage AND large amperage outputs.
The Facts – It is vital when deciding on a salt chlorinator to oversize the unit for your pool. You are improved off acquiring a chlorinator far too large for your pool, one that is undersized is a comprehensive squander of dollars. A chlorinator far too large can be turned back again or operate for significantly less time every day, making the mobile very last for a longer time. A unit far too little will indicate algae problems later on on if you do not operate it for for a longer time durations every day or add additional chlorine on a normal foundation. The large amperage output of the mobile will add amongst five hundred to one thousand watts per day or one. KW to one.5 KW to your electrical need and regular bill, at .11 per watt, this is $5 to $eleven every single month. Electric powered fees vary from .11 to .19 per KW and will not likely decrease in selling price.
There is no upkeep on a salt h2o pool.
Actuality – All salt h2o generator cells have to have cleansing every single 90 times. This have to be carried out ahead of the calcium establish up within the mobile housing becomes one massive block. If not cleaned for six months, 4 pricey points arise, (even with the unit turned off the scale nonetheless types): – The mobile housing breaks when you endeavor to clean it. – The mobile life shortens as the large voltage/amperage are unable to penetrate the scale on the plates. – The pool becomes a swamp when the mobile scales up. – The electronic box blows – due to scale on the mobile or salt ppm above 5000 in the pool. It is also really important to observe the salt stage in the pool. A lower salt stage (significantly less than 2000 ppm) will bring about oxygen manufacturing and harm the platinum team metals on the mobile anode, therefore, shortening the life of the mobile. It is recommended that you check out to continue to keep the salt stage at the greater conclusion of the manufacturer’s scale, for your certain model.
With a salt h2o pool, the operator Must preserve a right pH or the pool will scale, stain brown and ruin the mobile. Also cyanuric acid concentrations have to be managed or the chlorine will rapidly dissipate out of the pool.
Right before you obtain a system and throw 200 to 500lbs of salt in your pool, bear in mind an previous time period – “Salting the Earth”, 2000 years ago mankind understood improved.
