Automation is your answer. You can schedule the control of your pool or spa right from your house. Systems that are on the market are designed for ease and simplicity.

Your pool pump, heater, salt system and spa can be wired into the Automation System. You can even add a wireless remote or use your smart phone. No more trips out to the pump to turn it on and off - do it from inside your home. Want the spa hot and ready for you when you get home from work? Use your phone to turn up the temperature. The type of system you will need will depend on what type of pool or spa equipment you have. Your swimming pool dealer will be able to provide this answer.

Systems are designed to operate a pool, spa, or both. Push a button from inside your house to warm up your pool or spa so they’re ready for you when you need that time to relax. Lights for pool or spa or both can also be added to these systems. Special valves with powered actuators can be added to turn on the water to your slide, waterfall, step jets, or any other water feature.

Some of these systems have built in diagnostics to let you know all systems are functioning correctly or what needs to be corrected. These systems also have built in programmable features. These systems are designed to free up your time and give you more time to relax and unwind. See your swimming pool dealer or contact us to learn more today.



Zinc Anode

The in-line zinc anode is attached to the bonding wire, thereby protecting all metal parts (heaters, lights, rails, etc.) from galvanic corrosion. Zinc anodes will sacrifice themselves and corrode before all other metals in the pool. Zinc anodes need to be replaced approximately every 4-5 years on average.  Many factors can affect how quickly it will need to be replaced.  We have encountered some pools where the zinc anode had to be replaced every year.

Any time you have different metals (copper, stainless steel, etc.) in a salt water pool, you create a battery. Some amount of current flows between the metals. The electrons that make up the current are supplied by one of the metals, giving up bits of itself in the form of metal ions to the pool water. This is called galvanic corrosion. Galvanic corrosion causes plaster discoloration and metal erosion. The best way to inhibit the effect of galvanic corrosion is to use a zinc anode. Zinc is a metal that gives up its metal ions faster than other metals in the pool. In other words, the zinc anode will erode instead of other metals (pool light, rails, heater, light niche, ladder, etc.). The zinc ions will not discolor the pool plaster. The zinc anode should be replaced after half of it has eroded.

Galvanic corrosion can also occur pools that do not use salt water. Any stray electrical current around the pool area can cause it. Also, many localities are now requiring that the pool water be bonded. The inline zinc anode also performs this function.

Automatic Chlorinators

The automatic chlorinator is a very efficient way to chlorinate your pool with large or small Trichlor tablets or Bromine slow-dissolving tablets to make sanitizing your pool or spa easy and automatic. If you do not have this unit, your options are;

1. Put the tablets in a floater

2. Put the tablets in the skimmer basket

3. Put the tablets in the pump basket

Any one of these three options will present you with a problem. The use of a floater is the lack of the ability to get the proper amount of chlorine in your pool. Since you do not have water flowing into the floater to dissolve the tablets, your pool water is going to be usually low in chlorine with the result being green water and algae build up.

When you place the tablets into your skimmer basket, they dissolve very quickly and it becomes very difficult to maintain the proper amount of chlorine in the pool. It can also deteriorate your skimmer basket and the seals and o-rings on your pump and filter. If you turn the pump off, chlorine will flow back into your pool causing a white stain in front of your skimmer.

If you place the tablets into your pump basket, they are also dissolving very quickly here and chlorine levels could be too high. This also will cause your pump seal to start leaking and your o-rings to wear out quickly with possible pump damage.

The automatic chlorinator is installed after the filter in the water return line going to the pool. It should be the last thing the water goes through before returning to your pool. These units are completely enclosed systems – no escaping fumes. Simple, trouble-free designs with no special venting required. Top loading makes it easy to add chemicals. You remove the lid and place the tablets inside. There is a control knob with different settings that will let you control the amount of chlorine being released into your pool. Note that every pool is different and you will need to adjust the settings based on your particular pool. Automatic chlorinators save time, reduce manual handling of chemicals and take the work and worry out of keeping your pool sparkling clean and ready to use.



Floating Chlorine Dispensers

Are you using chlorine tablets (1” or 3”) or chlorine sticks in your pool? If you are what are you using to get this chlorine into your pool? You may be using a Floating Chlorine Dispenser or Chlorine Floater.

The Floater, as the word states, floats around your pool and tablets slowly dissolve. You do not have water passing thru it very fast to dissolve the tablets or sticks rapidly. This system may work perfectly well for many small pools, spas, or swim spas. However, once you start getting to mid to large size pools (and occasionally some smaller pools with heavy bather loads), your pool water could become cloudy, algae could grow and the liner could become very slick due to the chlorine being released too slowly. The warmer it gets, the more chlorine demand your pool needs and that demand will be hard to satisfy with a Floater.

If you are having problems maintaining your Chlorine residual with a floater and you want to continue using tablets then take a look at an automatic chlorinator. This unit can be plumbed into your return line which has water flowing through it going back into your pool. You can use either 1” or 3” tablets or chlorine sticks in the Chlorinator. The Chlorinator has a control value on it that can be adjusted. You can regulate the amount of chlorine getting into the pool.



Is It Time To Add A Gas Heater To Our Pool?

The heaters on the market today are now fast, efficient, compact, quiet, safe and eco-friendly. Now you do not have to wait until the temperatures are in the 80’s to enjoy swimming. On most of the new gas heaters there are no pilot lights; just push button digital controls plus a user-friendly indicator light makes operation and monitoring so simple.

Gas heaters are available for Propane or Natural Gas. If you live in an area with natural gas, your house might have a gas meter already attached to the house. You should get a licensed plumber to check this meter to make sure it will handle the additional BTU’s of the gas heater. BTU options will vary from 200,000 up to 400,000.

The size BTU heater you will need can be determined by your local Medallion pool dealer but it will depend on how many gallons of water you have in the pool and if you are looking to keep the pool heated all the time or only on demand. If you are going to install a propane heater, the local pool dealer can install the heater but you will need a propane company to make the connection from the propane tank to the heater. If you do not have a propane tank, the gas company can have one installed.

Placement of your new heater is very important. Refer to the manufacturer’s manual for proper placement. Here are some examples; if the heater is going under a deck, you must have proper clearance from heater to deck. If the heater will be installed indoors, the gas fumes must be vented outside. The heater can’t be installed next to your heat pump. The proper placement information will be found in the heater manual.

A gas heater is a great way to extend your swimming season. Depending on where you live, the proper size heater can give you 60 more days plus of swimming time. Now is a good time to visit your local pool dealer to learn more about the different heater options. While you are there, be sure to ask about a solar cover to help your heater be more efficient.
