Save your money and dont install one. The Pool Defender Sacrificial Zinc Anode is designed to prevent the damage caused by salt water sanitation systems.
The sacrificial anodes have a difficult task since they have to protect what is already a very active aluminum assembly.
Sacrificial zinc anodes for salt water generators. Sacrificial Zinc Anodes for Saltwater Generators There are some materials that are more susceptible to corrosion at higher salt levels. Though obviously low-grade stainless steel and naked steel and zinc are problematic they arent usually used in pools in the first place high-grade stainless steel is used instead. A zinc anode is a device that protects metal components and hardware from corrosion in a salt water pool by conducting electric currents that pass through the salt water when chlorine is produced.
The sacrificial anode anti-electrolosys device is relatively easy to install affordable and available in numerous shapes and sizes depending on where you would like to install it in your. Zinc anodes are the preferred choice in metal alloys for saltwater applications that need a sacrificial anode because the alloy is less resistant to the saltwaters electrolytes. The zinc in essence stops the oxidation happening to the other metal part as the zinc dissolves away.
Pools with chlorine generators typically will have a higher concentration of salt 3000-4000 ppm but in saying that it is not uncommon for a standard pool to have a salinity close to that required to operate a chlorine generator as the daily additions of chlorine will tend to slowly raise the salinity until spillage and backwashing requires adding water back into the pool. A sacrificial zinc anode. Sacrificial anode Zinc round bar 20mm.
Corrosion protection in salt water Available as round bar 20 x 340mm From standard to customized anodes. Corresponds to US MIL Spec. A-1800 1K Remains electro-chemically active in salt water Uniform corrosion pattern reliable electrical capacity with long life.
A zinc anode is a critical part to have with your salt water system. This one happens to be placed in the skimmer there are also solutions for plumbing it directly into the system. Ask the Pool Guy Pool Guy - Bonus Material zinc anode.
You dont put the sacrificial anode in the pool water itself. The sacrificial anode is put into moist soil ie. Grounded and electrically connected with a wire you then attach to the bonding wire that connects all the metal in your pool and the equipment at the pool pad that is in contact with the water.
As for putting the zinc sacrificial anode in the pool water electrically connected to the bonding wire the zinc ions are not likely to stain since not that much zinc is expected to be added and zinc oxideshydroxides are more soluble than those of copper and ferric iron. The sacrificial anodes have a difficult task since they have to protect what is already a very active aluminum assembly. Initially the anodes for these units were made of zinc but in response to corrosion problems Mercury and JohnsonEvinrudeOMC started selling the aluminum anodes in the early 1990s.
Pool Defender products are the simple way to guard the entire pool. Electrical currents present in the pool are enhanced in saltwater causing corrosive damage to metal pool parts even when the pump is off. The zinc anode provides an easier path for electrical current protecting expensive metal pool components.
Generally speaking sacrificial anodes made of zinc work well in salt water magnesium anodes work best in fresh water and aluminum anodes work well in salt brackish and fresh water. It appears the use of aluminum sacrificial anodes satisfies both the environmentalists and boat operators something one rarely sees. The problem of galvanic corrosion can be easily stopped by using a sacrificial Zinc Anode this simply allows the anode to erode before all other metals in the water.
Thermalec can provide you with the solution. Zinc anodes designed for the pool industry to fit into new or existing pools. No you dont need one if you dont have metal in or around ladderrailing anchors and such the pool and you especially dont want one if the manufacturer says not to.
The anode is there to prevent premature corrosion of metals due to salt if you have no metal it cant corrode prematurely. Save your money and dont install one. Zinc anodes also known as sacrificial anodes play a key role in the maintenance of your boat.
The term zincs has become synonymous with sacrificial anodes being that zinc was the original material used for this purpose. However other metals such as aluminum and magnesium also work as sacrificial anodes. The Pool Defender Sacrificial Zinc Anode is designed to prevent the damage caused by salt water sanitation systems.
The zinc anode will erode instead of your expensive pool components The Pool Defender Sacrificial Anode is tied into the pool bonding wire thereby protecting the entire pool Simply replace the anode after half of it has eroded typically in about three years. Magnesium anode rods tend to be consumed quicker than Aluminum or AluminumZincTin anode rods due to the higher voltage they create during the sacrificial process. AluminumZincTin Anode Rod This particular combination of metal in anode rods is often used when foul odor in water is present.
Another option less expensive but less effective is a disc-shaped zinc anode that sits in your skimmer basket. Zinc anodes are also called sacrificial anodes because they corrode instead of the other metals in your pool. Zinc is a weak metal so the anode sacrifices itself to galvanic corrosion so the other metals in your pool and equipment dont have to.
It also helps to prevent calcium scaling. This is an absolute must for a salt water. Zinc make a great choice for a sacrificial anode because its a highly active metal that is capable of being sacrificed.
Zinc anodes are recommended for salt water applications. They are most commonly used in marine applications such as. If you have a salt water chlorine generator I recommend having an anode in your pool as salt is so corrosive.
Pool Tool is the go-to supplier for swimming pool anodes. You can find zinc balls on-line with a simple keyword search. So do zinc anodes truly work.
Yes they will inhibit corrosion its to what degree thats difficult to measure. One of the key components that is easy to overlook are the sacrificial anodes or what are commonly referred to as boat zincs or simply zincs. These silent partners protect the metal parts of your boat lift from galvanic corrosion.
This occurs when any two dissimilar metals are physically or electrically connected and immersed in water. Zinc anodes come in various shapes and sizes. From spherical devices to disk-shaped weights each tool serves a specific purpose.
However they all provide the same high level of protection. Choose the anode that fits the needs of your saltwater pool system. Zinc anodes are relatively easy to install with minimal instructions.
