Can I use the HTH® Green to Blue Shock System for my pool?
We want to make sure the HTH Green to Blue Shock System will work best for you.  HTH Green to Blue Shock system is a 2-part granular product that is designed to transform your green water to a clear, sparkling, sea of blue.  It may not be right for every pool, though.  This product will work properly if your pool is green because of algae growth (usually a dull green).  If your green pool water is caused by metals (usually a green tint to the water), then the HTH Green to Blue Shock System will not be able to turn your pool clear. 

You will need to be able to vacuum to waste for this product to work properly.  This means you need to be able to vacuum the debris out of the pool without it passing through the filter.  This product is not designed to work for pop-up pools or pools with D.E. or cartridge filters if you are not able to vacuum to waste. Watch this video to learn step by step instructions on how to use HTH Green to Blue Shock Treatment in your pool.

If you have any questions or are uncertain whether the HTH Green to Blue Shock System will work for you, please call our pool care experts at 866-HTH-POOL (866-484-7665).

What products should I add first to start up a new pool?
For start-up, first, you want to "balance" the water so that it is neither corrosive nor scaling. This is done by testing your water with a pool test kit and adjusting the alkalinity in the range of 60 and 120 ppm, the pH in the range of 7.2 and 7.6, and the calcium hardness in the range of 200 and 500 ppm. Second, you'll add a chlorine-based sanitizer to kill any bacteria that hinder healthy swimming and destroy organic contaminants. Third, adding an algaecide is an important preventative step to maintaining sparkling blue, crystal clear water. Always read and follow label instructions. 

How soon can I swim after adding pool chemicals?
You should wait to enter the water until after all treatment chemicals have been fully dispersed and dissolved in the water. Always follow product label directions. Making sure the water is perfectly balanced is very important. Swimmers should not enter the pool unless the pH is in the range of 7.2 and 7.6 and the available chlorine level is within the range of 1-4 ppm when tested with a pool test kit. Once the levels are within range, you're free to swim.

How long do I wait before adding the next chemical/product?
When you first fill a pool, it is important to adjust the alkalinity first before adjusting the pH. Depending on your pool's circulation and other factors, it may take a while for the alkalinity to equilibrate after your adjust it. Be patient and wait a day or so before making any further adjustments to the alkalinity or pH.

For other pool chemicals, there is not a pre-determined waiting period, but as a general rule, you should make sure that the chemicals are fully dissolved and dispersed before adding any other chemicals. Always follow label directions.

My pool is cloudy - How do I make it clear?
Cloudy water is likely to be caused by one of five things:

  Improper Water Balance
  Environment and Bather Load
  Poor Filtration
  Poor Circulation
  Incompatible Chemicals

To pinpoint the problem, begin by testing your water. The solution could be as simple as correcting a high pH. If your pH is too high, lower it to between 7.2-7.6 using HTH® pH Minus. Another possible cause is environment and bather load. Pools located in heavily landscaped areas are candidates for hazy water because leaves, dirt and other debris can be carried into the pool. High bather load may also be associated with cloudy water. To treat cloudy water that is caused by contamination from the environment or bathers, adjust pH in the range of 7.2-7.6. Wait two hours, retest and then shock treat with an HTH® shock treatment. Run the filter for 24 hours or until the water clears. Poor filtration or poor circulation can often lead to cloudy water. Routinely check your filter and backwash/clean according to the manufacturer's recommendations; always rinse the filter after backwashing. Run your filter for at least 12 hours a day during the hot summer months. Check the returns on the pool to be sure they are directed toward the bottom and away from the skimmer in a circular flow pattern. Finally, chlorine is not compatible with every chemical. Fertilizers, pool surface cleaners, and other products used around the pool are a few examples of chemicals that will produce cloudy water.

How do I treat algae?
Test your pool water! You're likely to have low free available chlorine and possibly a high pH level. Brush pool sides and bottom. Backwash, bump or rinse filter. Adjust your pH to the 7.2-7.6 range. Wait two hours, and then shock treat with an HTH® shock treatment. Brush the pool walls and then vacuum to waste. Finally, add a maintenance dose of an HTH® algaecide.

I've added too much algaecide to the pool - what can I do now?
The primary health effect you might experience from an algaecide overdose would be eye/skin irritation. If you are experiencing eye irritation from an excess level of algaecide, the only way to lower this level is to wait until the algaecide concentration decreases due to water loss from backwashing and splash-out, or you can partially drain and refill the pool water. If you have used over two and a half times the normal product dosage, please call our ACEAN line for advice at US toll-free 1-800-654-6911.

How do I assemble vacuums?
To view our instructional video on assembling your HTH® vacuum, please click here.

If your pool has a skimmer, you will need the HTH® 35' Universal Vacuum Hose. HTH® PRO 8' to 14' 3-Section Telescopic Pole, and the HTH® Multi-Surface Vacuum Head. These three items are essential to vacuuming your pool. To begin, make sure your pool's filter is turned on and running. Next, attach one end of the vacuum hose snugly into the vacuum head. For the HTH® Multi-Surface Vacuum Head, attach the clear vinyl adapters to the 1-1/4" vacuum head. (If not attaching the HTH® Multi-Surface Vacuum Head, you may need to discard the clear vinyl adapter if the vacuum head is 1-1/2"). Once this is complete, fasten the vacuum head to the telescopic pole. Once assembly is complete, place the vacuum head into the pool water andhold onto the pole so that is not submerged completely under the water. Place the non-swivel cuff end of the hose over the water return valve and hold it there until you can no longer see bubbles coming out of the vacuum head. Once this happens, the hose has been filled with water and can now be connected to the drain hole. Remove the skimmer basket and connect the non-swivel cuff end of the hose into the drain opening. If you have a skimmer vacuum plate, the skimmer basket may be left in and the hose can be attached into the hole at the bottom of the skimmer basket.

Now, your vacuum hose is ready to vacuum your pool. Begin vacuuming and enjoy your clean pool!

If you have a spa or "pop-up" pool, use the HTH® Spa & Small Pool Vacuum.

To begin, connect the vacuum tank to the wheels and bristles apparatus. Next, assemble the vacuum handle by connecting the aluminum tubes and rubber grip handle. Insert the handle into the connector block and screw to tighten. However, if you'd prefer to connect a telescopic pole, simply remove the handle connector by removing the pin. Then, attach the universal handle connector (white handle) into the same location and re-insert the pin. Lastly, attach the garden hose to the valve connector. You can then submerge the vacuum under water. To begin vacuuming, use a high flow rate of water from teh garden hose to create an adequate venturi effect. The water pressure from the hose may need adjustment to create proper venture action.

How do I use the pool patches?
To view our instructional video on assembling your HTH® vacuum, please click here. The HTH® Vinyl Patch Kit mends small underwater cracks and tears on inflatable pools and light gauge vinyl pools. No need to empty the pool. Simply cut out a patch and use the adhesive supplied and apply. It's that easy!
