However, if you decide to do it yourself, we will be providing some tips over the next few days to help you do it well and maybe save you some time and money in the process.

Before we start let?s review some things to make sure everyone is on the same playing field:

This guide is for pools that were blue and clear last season and just got away from you in the off season. If the pool sat dormant for several seasons and the pool has turned into a pond, these steps may not solve your problems. Please call a professional. A drain and scrub or acid wash may be the better course of action for your pool.
If your pool is full of soapy algaecides and or Biguanides, this guide will not work for you. Please call a pool professional to come check out your pool water as you may need to drain water before attempting to clear the pool.
Read the guide through before going shopping. The shopping list assumes a normal sized backyard pool, if your pool is oversized - buy more, if your pool smaller than average - buy less. The shopping list assumes you have a pool hose, vacuum and good tele-pole. If you don?t have these things already you may want to spend your money on a pool professional.

Step One: Get the Debris Out

It will take more chemicals and more time to turn the pool around. We recommend using a deep, sturdy leaf net. Prevent using shallow leaf nets that only clean floating leaves off the surface. They won?t be sturdy enough to pull debris from the pool floor which is key in getting your pool in swimming condition. Have a trash can(s) nearby for the debris to ensure that they don?t end up falling back in your pool.

If it is more than you can handle, call in a professional. We have career trained professionals who will be more than happy to assist!


Step Two: Get the Pool Chemicals working for you

Your pool is probably a green cloudy mess. You?ll want to add two chemicals to the pool to begin the clearing process:

Pool Acid ? also known as Muriatic Acid
Pool Bleach (bought in the big yellow jugs) ? often improperly referred to as liquid chlorine, it is actually Sodium Hypochlorite

Safety first - wear eye protection and appropriate clothing and gloves to protect your skin when dealing with chemicals. Add 1.5 gallons of the pool acid to the pool. The goal of the pool acid is to drive down the pH of the water so that the chlorinating compound will be effective.

Help, How do I clean a green swimming poolWe teach our technicians to slowly pour the acid behind us in the pool while walking on the pool side. Be aware of the pool deck and surroundings ? Don?t Fall In! Don?t be in a hurry and don?t splash the acid. Once the acid is added triple rinse the one empty jug putting the first two rinses in the pool.

Next add the pool bleach. The jug should have an air cap (small cap) and a dispensing cap (large cap). Remove both and pour in the shallow end of the pool. Repeat with three whole jugs or 7.5 gallons of pool bleach. Follow the same precautions with eyewear and gloves, avoid splashes and rinse any area that gets bleach on it thoroughly with water. Rinse the jugs at least twice with the first rinse going back in the pool.

Now the chemistry can get to work for us.


Step Three: Circulate and Brush

The chemicals are in, now let?s get the water moving. If your pool has a recirculate mode on the multiport that?s what we want. With the system off, put the multiport to recirculate and turn on the system. This will bypass your filter and just move the water which is what we want at this time.

While you let the chemicals work, I suggest cleaning your old cartridge element even if you ended up replacing it. Set both the new one and the old one aside you?ll need it later.

After about 30 minutes of water circulation with the chemicals in the pool, brush the pool floors and walls. Your brush should be in good shape and strongly backed with metal. Our professionals use one that is similar to this:

The pool is going to turn into a cloudy green/blue mess but do your best to brush everything- floors, walls, and steps, even though you can?t see. When you are done brushing turn the system off at the breaker, we don?t want the water circulating accidentally.

Step Four: Add More Chemicals into your Pool and Wait

Hopefully the water is cloudy blue - if not it will be. It?s time to add more acid and chlorinating compound.
