Everyone knows that electricity and water are typically a bad mix!  EVERY pool/spa should have a GFCI located between the breaker box and the service controller/switch. In the event the GFCI has to be RESET, there is a good chance it “popped” for a reason. Give us a call and we can come take a look at what’s going on. It could be as easy as changing out the bulb/gasket, but keep in mind, these days there are options such as low voltage lights (highly recommend) as well as color changing lights.

If you spa is draining over night while the pump has been off, its most likely the check valve that needs to be replaced. It is a common pool part that tends to fail after about 12-24 months.

In the event the filter pump (or any pump for that matter) won’t turn on, check to see if any of the other pumps turn on. Assuming they do, we suggest leaving any/all of those water feature pumps running continuously to assist in circulating the water until the main filter pump can be fixed/replaced. The actual “problem” could be a number of things of which will require a service technician to come out and check for voltage at various locations to determine what has failed.

Laws are changing in July of 2021 which in most cases will require an updated variable speed pool pump to be installed in replacement of you main filter pump. Give us a call and we can discuss the options on upgrading your pump and the savings that comes with it!

In the event we all need to prepare for a hurricane, we suggest worrying about your pool last! Getting supplies, having an exit plan, staying safe are all more important then worrying about your pool. The pool can be fixed, your life is more important. Leaving your pool running to keep up with all the rain is a good idea. DO NOT DRAIN your pool!

When the temperatures are going to be at or below freezing you should let the pumps run during the time the temperatures are at or below freezing. Most pools with automation have a built in freeze protector, and many pools with time clocks have a separate freeze protector that turns the pump on at a desired set temperature.   

Green or algae filled pools are no fun to deal with!  Typically they require lots of chemicals, brushing, vacuuming, filter clean(s) over several days and can become quite costly to get back to looking normal. If it’s beyond your control let us know and we would be happy to assist in getting your pool turned around and looking like Paradise.

Backwashing (flushing) the filter allows the filter pressure to return to normal by reducing the amount of dirt, oil, or dead algae. This, in turn, will get the pool circulation back to normal. It is also important to be sure and ‘recharge’ your filter by adding diatomaceous earth (DE).
You should have your pool water professionally tested at least once a week or after a heavy rain for proper levels of sanitizer, pH and total alkalinity.
The most common cause is low water level. Another cause can be skimmer and/or pump baskets that are clogged.
During the hottest parts of summer, pools can lose quite a bit (1/2 to 1 inch a week) of water due to sunlight, heat, and splash out. If you are concerned that you may have a leak, call Paradise Pool & Spa at (936) 321-7665.
A few things contribute to this problem – the most important is filtration. Sometimes cloudy water can be solved by simply cleaning (backwashing) the filter or balancing the water. Chlorine demand might be your problem.
Actually green hair is caused by metals dissolved in the pool water which can come from a variety of sources including a low pH level, some kinds of algaecides, pool heaters being damaged due to improper water balance, source water, etc.
High total chlorine can cause your eyes to burn but usually it’s due to poorly balanced water. Improperly balanced pH is very likely the cause.
You will need to follow the recommendations provided by our Staff or what is listed on the chemicals that you have used. The wait time can vary quite a bit depending on which chemicals you have added.
There are many factors that determine this which include size of your heater, pool and spa as well as starting and desired water and air temperatures. Generally speaking, in the middle of the winter, it will take about 45 minutes to heat your spa to 100 degrees. On average, when heating your pool, it is estimated that temperature will go up about 1.5 degrees every hour that it is heated.
Your pool water needs to “turn over” every day. Most pool pumps and filtration systems take about 10 hours to do this. We also recommend that your allow your cleaner to run 4 hours each day. Any water feature pump (waterfall, river, stacked stone) should run for at least 20 minutes a day to keep the lines clear of algae.
Dirt and oil from swimmers are the biggest culprits when it comes to ring around the pool. Regular brushing using the proper pool cleaner is suggested. Also, depending on the type of material used for pool’s waterline, it could be “scale”. Contact us for options on how to remove the ring and prevent future occurrence.
This setting depends on water temperature and how often you use your pool. Generally during the summer months your salt system should be set around 70%- 85% and 15%-25% during the winter months.
You should brush your pool weekly. It is important to brush your pool to keep it clean by removing debris from the floor and walls of your pool. When you brush off these small particles into the open water, the filter will filter it out from the water, leading to a cleaner pool.

When brushing, be sure to apply firm pressure against the pole, brushing steps and benches first, then walls and finally the floor from shallow to deep end.
