Swimming Pool OPENING

Get your pool started each season the right way!

Starting or opening up a swimming pool is pretty simple, you don't need to hire a pool service company. But it does require a bit of work and a couple of extra hands. Honestly, it's best to start a week or two before you want to open it for not only best results, but  also to take  some of the "last minute" stress away.

No matter whether you have an above ground pool or an inground pool, the basic work is the same or similar. PoolSpaGuru.com has all of the pool supplies you'll need. Follow these simple steps with details & tips:

1. Remove all the leaves, dirt & debris from the winter cover BEFORE removing it. I can't tell you how many times I've seen people let all of the winter mess just go right into the pool! Talk about extra work. I've seen really clean winterized water  become black with the leaf & twig tea & other debris from the  winter cover. It's well worth the effort to spend a couple of half-hours scooping excess & accumulated leaves from the top of the cover.  Remember, it's not just last fall's leaves; it's the spring pollen, those tree helicopters or "spinners" & pine needles too.

2. Remove all winter & ice expansion plugs (Gizzmos). You can't start the pump & filter system if water isn't flowing from pool to filter & back! Be sure to replace the respective directional returns (eyeballs), suction grates (usually used on lower suction fittings), Circulator fittings, etc. If you are using standard, stationary eyeballs, remember to point the flow of water DOWN toward the bottom of the pool to optimize the circulation.

3. Bring the Water Level up to normal operating level. If the water on top of the cover is relatively clean & algae free, use that water to fill the pool. It's free! It may be a little dirty, but that's okay, it will be treated with the rest of the pool. At this time it's a really good idea to add an algaecide to the water & a natural pool enzyme such as ActivNzyme Enzymatic Clarifier  to start cleaning up the water and prepping it for the initial shock.  If you are adding fresh tap water to top the pool off, add a good metal and mineral stain & scale control product such as Jack's Magic Blue Stuff or Pink Stuff to prevent sudden metal stains, especially iron or copper, when the pool is first shocked.

4. Carefully remove the winter cover. Clean it up, fold it up & store it away. When cleaning, use a good cleaner that is specifically made for cover material such as BioGuard Stow Away or Natural Chemistry Cover Cleaner.   A good chemical cleaning of the winter cover will lengthen the life of the cover by removing the dirt & soil from the fabric. Not only  will your cover get clean, but these products will also control the  growth of mold & mildew which shorten a cover's life while stored  over the summer. Think of it this way: you wouldn't put dirty clothes away in the closet for the next season would you? 

5. Hook up the filter system.  Properly attach the correct hoses or pipes to the proper valves or fittings on the pump and filter. Even I've made this mistake: the right  hose goes on the wrong filter fitting & 2 weeks later, the pool is still not clear! Here's the easiest way to remember: basket to basket  (skimmer basket to pump basket) and hole to hole (exit to pool - hole  on filter valve or tank body to return opening on pool  wall). Be sure  to properly lubricate all multi-port or shut-off valve  O rings with a  good silicone lubricant.  Not only will you give the gasket added life,  you'll help it seal more easily too. Don't over-tighten clamps on above  ground hoses; over-tightening will often crimp the hose allowing air  leaks. REMEMBER: replace ALL of the drain plugs to the pump, filter tank & heater (if equipped).

6. When starting the pump for the first time, be sure to prime  the pump with water. Don't start it dry, not only can harm be done to  the pump, extra stress & strain is placed on the entire system. If your pump is below the water level, as on most above ground pools, priming probably isn't necessary because the water is naturally falling or flowing down to the pump (we call that a gravity feed). If the pump &  filter system is more than 3 ft above the water level, priming is an absolute must. Keep in mind that the system could take several minutes  to catch and start in this situation. SPECIAL NOTE: it  is VERY normal for LOTS of bubbles to come out of  the return fittings  when first starting. Even for up to 24 to 36 hours, some bubbles (air)  will remain in the plumbing system while it returns to normal operation. SPECIAL TIP: to  make the filter start easier, open the air bleeder valve on the top of  the filter tank when the filter starts. You will hear a big whoosh of air as it is pushed out of the  filter. When water gushes out, replace  or close that valve. If your filter does not have a manual air bleeder,  temporarily remove the  pressure gauge for the same results.

7. Clean & vacuum the pool of all dirt & debris. Get all of the excess stuff out of the pool  before adding shock & start up algaecide, especially if the water is  relatively clear & clean. The less stuff in the  water, the more  effective your initial shocking and chemical treatment  will be.  Be sure to vacuum & brush the side walls of the pool to remove any build-up of biofilms there as well. A Wall Whale makes brushing easy - just one hand & 10 minutes or less each week.


8. Clean the liner or tile line with a good quality pool surface cleaner like BioGuard Off the Wall Surface Cleaner. DO NOT use household cleaners as they can affect the pH and add phosphates to the water which will contribute to algae growth later on. This is where most of the winter's scum has left its mark. Clean it off now while it is still soft & easy to remove rather than when it bakes in the sun and is more difficult to clean. Prevent this scum line (also known as a biofilm) from reforming with regular cleaning or by  using AquaFinesse Pool Pucks.

9. Add your initial doses of shock & algaecide. NOW you can add the chemicals! When starting, don't skimp. Do a good heavy shocking & proper dosing of algaecide at opening. In the long & short run, you're going to save a lot more money by doing this the right way. 

10. Allow the opening or start up chemicals to circulate for 24 - 36 hours before doing any testing or water balancing. Why  wait? There are 2 reasons:

1. Additions of Shock & algaecide will change the water chemistry and water balance. That little bit of time will allow the levels to  settle back down for a more accurate reading.

2. Some of the chemicals already in the pool water from the prior  season  and winterizing will be settled toward the bottom of the pool.  This is especially true of cyanuric acid typically known as pool conditioner or stabilizer. If the water is not allowed to circulate  & stir up what's on the bottom, you will end up adding stabilizer that, more than likely, doesn't need any additions. This is a great way  to save  money. By the way, NEVER add conditioner or stabilizer unless  the pool water needs it and only if the test shows a level of 20 ppm or less.  Stabilizer or cyanuric acid levels should be no higher than 60 ppm. Higher levels are simply wasteful and provide nothing for the water balance.

11.Install ladders & deck equipment.  Be sure to securely tighten anchor bolts, diving board bolts &  slide anchors (if equipped). Check to make sure the bolts and hardware  are in good condition. Replace worn or corroded nuts & bolts for your safety.

12. Filter 24 hours before bringing in an Opening water sample for Testing & Analysis. Adjust pH, Total Alkalinity & Calcium Hardness as needed.

13. Chemically clean the filter  with BioGuard Kleen It or Strip Kwik Filter Cleaner after 2 weeks to  remove the filtered winter stuff. A more natural alternative is Natural Chemistry Filter Perfect which uses natural enzymes and acids which are not only great cleaners, but they are not harmful to area landscape and plantings.   


Chemically cleaning the filter about every 8 weeks lengthens the life of the filter media and promotes longer filter runs. Simple backwashing just rinses off excess dirt & debris but doesn't remove accumulated greases & oils.

Chlorine shock:  use un-stabilized Cal-Hypo such as  BioGuard Burn Out 3 or Burn Out 73  products on  an initial spring shock. Burn Out 3 & Burn Out 73 get  in, oxidize the waste, then gets out (gasses off).  Use these products at a rate of 3 to 5 lbs per 5,000 gallons for best results.   Do NOT use a non-chlorine shock with the initial start up. You need to have a good chlorine residual. Liquid chlorine bleach is OK, but is  very weak (about 11%) when compared to Cal-Hypo (about 60% and higher).

Initial Algaecide:  don't skimp with the algaecide! Always use an algaecide that has at  least 30% active ingredients. BioGuard Back Up 2 or Algae All 60 contain 40% and 60% active ingredients respectively & are 2 of the best  algaecides on the market that kill, prevent and control swimming pool algae. Be careful using algaecides with copper as an active ingredient; improper use of copper based algaecides may lead to staining of pool surfaces. Gallon jugs of algaecide typically contain less than 10% active ingredients and are a waste of money. Follow the label directions  for an INITIAL dose, typically 1/ 2 quarts per 10,000 gallons. For a  GREAT START, use BioGuard Pool Opening Complete... just a great product!

After adding the initial shock & algaecide, be sure to run the filter for 48 to 72 hours continually.  DO NOT backwash the filter during this  time. Let the filter and the chemicals do the work.

Winterize your pool the right way for a great start next year!

When the season is over, proper winterizing makes spring start-up simpler & quicker. Use this checklist...

ALL POOLS (vinyl liner only):
[ ] Remove ladders & any deck equipment

[ ] Vacuum pool & remove all debris

[ ] Add Chemicals to pool according to instructions

[ ] Clean & protect the waterline with Off the Wall Cleaner

[ ] Drain Filter tank of ALL WATER. Leave winter drain plug off!

[ ] Put all eyeballs, drain caps, gauges, etc. in pump basket for safekeeping

[ ] Clean DE grids or Cartridge with BioGuard® Strip Kwik, Kleen It or SoftSwim Filter Cleaner

[ ] Bring pump/motor indoors for winter

[  ] Winterize heater (if equipped) according to  manufacturer's  instructions. Failure to do so will cause winter damage  and freezing.

[ ] Remove return eyeball(s) and install plug(s) or cap(s)

[ ] Winterize skimmer(s). See below for pool type

[  ] Put on Winter Cover. All Solid covers  should FLOAT on the top of the  water DO NOT drain pool lower than  bottom of skimmer (mesh covered pools  only)

If a pillow is used, inflate only to about 2/3 full. Over inflation will cause air leakage.

[ ] Properly store maintenance equipment

INGROUND POOLS (vinyl liner only):
[ ] Thoroughly blow out underground lines

[ ] Install Gizzmo(s) in skimmer(s) or Aquador(s)

[ ] Add pipeline antifreeze at the rate of 1 gal. per 20 ft of line run

[ ] Store diving board (if equipped) in a flat, horizontal position

[ ] Safety covers should be re-tightened at time of installation

[ ] Add additional dosage of Back Up Algicide in the spring if safety cover is used

[ ] Winterize skimmer with AQUADOR

[ ] Tighten cable securely around cover

[ ] Use Cover Clips to further secure cover. DO NOT HANG BOTTLES. Bottles hung from the cover will tear the cover!

[ ] Remove leaves and heavy debris that accumulate on cover

[ ] Remove excess water from top of cover (A submersible cover pump works best).
