Product Description

In The Swim Super Pool Algaecide
Super Algaecide

In The Swim Super Pool Algaecide

In The Swim Super Pool Algaecide is a concentrated, non-foaming formula, allowing the use of smaller amounts which makes it easier to measure. Super pool algaecide is fast acting so it saves time and money. In the Swim Super Pool Algaecide can apply as a treatment or as a maintenance product. Works on many types of algae. Can be applied to in or above ground pools.

Before adding In The Swim Super Pool Algaecide, make sure to brush your pool and clean or backwash your filter. Empty skimmer and pump baskets. Turn on the main circulation pump. Super chlorinate according to water volume and interior type. This will build a chlorine residual.

Pour the recommended dosage into a chemical safe container. Mix with 9 parts of pool or hose water. Pour the diluted mixture around the perimeter of the pool. Safe to swim immediately.

Targets Multiple Algaes

  • Contains 23.5% Copper Triethanolamine Complex (7.1% chelated copper) as the active ingredient
  • Powerful and highly concentrated
  • Can be applied to inground or above ground pools
  • Treatment Dosage: 4 oz. per 10,000 gallons. NOT recommended for use in well water
  • NOTE: We are unable to ship Super Algaecide to California due to State Restrictions

Pool Care and Maintenance

It is important to maintain your pool/spa to keep it clean and healthy all year round. Good habits, such as cleaning your filter or emptying your skimmer basket, will ensure that your investment is protected for years to come. But most importantly, you and your family will be able to enjoy the swimming pool or spa each season.

Water Testing

Testing the water weekly or bi-weekly, depending on use and outside variables, helps keep your pool/spa water healthy. Utilizing a DPD or OTO reagent-based water test kit, test strips, or digital testing will help you monitor the pool or spa water chemistry.

Adjusting and Balancing

Adjusting and balancing your pool or spa water chemistry ensures that you will get the most out of the swimming season. The benefit of having good pH and Alkalinity levels is that it will increase the ability of your main sanitizer to kill bacteria. Balanced pool water chemistry will also reduce chemical and maintenance costs. Balanced pH and alkalinity help prevent corrosion and scale formation on the interior pool surface and surrounding equipment.

Chlorine Tabs

Pool Fun

Green to Clean

Sanitizing

There are many different types of sanitizers used in various pool and spa environments. Clean and healthy water starts by establishing a proper residual chlorine level with shock or concentrated granular chlorine. The most common way to maintain a proper chlorine level is by using trichlor chlorine tablets in either a floater or chemical feeder. Applying these steps to your normal maintenance plan will ensure the elimination of non-living organic contaminants, bacteria, micro organisms, and algae making your water safe to enjoy.

Pool Fun and Safety

Now that the water is properly balanced and sanitized, it’s time to get in there and have some fun! We recommend enhancing your outdoor living environment with games, floats or loungers, toys, and accessories. Get creative!

Safety is of the utmost importance, and there are many ways to help make your pool/spa safer. Having a life ring buoy, a shepherd's hook, depth markers, coast guard-approved life preservers, door and water alarms and having your local aquatic environment safety regulations on-hand will ensure a fun and safe environment for your family.

Treatment

Even after all your preparation, sometimes life happens and your pool or spa can get away from you. In those moments, we need to start back from the beginning with testing of the water. Now that you have a clear idea of the current readings, your next steps will depend on the type of symptoms your water is presenting. This may include an issue such as algae (green, yellow, black, etc.), cloudiness, living organics, debris, and other water conditions.

FAQ's

  • Q: What is the start-up dosage?
  • A: 4oz. per 10,000 gallons.

  • Q: What is the maintenance dosage?
  • A: 2oz. per 10,000 gallons.

  • Q: Can I use this product in my well water?
  • A: No, because the Super Algaecide is a copper based algaecide. Adding this product to your well water will just be adding more metals to the water.

  • Q: How often do I have to add this product to my pool?
  • A: It is recommended adding the maintenance dosage every 2 weeks.

  • Q: Will this product get rid of the algae in my pool?
  • A: Technically, no - algaecides just make the algae more susceptible to sanitizing capability of chlorine.

No algae, no chemical testing for me!
This product works great for us, no algae. I use along with Pool RX and Burn out 73 it keeps everything under control. Arizona summers can be a struggle against algae otherwise. We have been pool owners for 6yrs. We had no idea what we were doing originally. Struggled about 2yrs. We had issues with algae, first green than mustard. L----- pool supply just kept telling us to do this and that. The amout and cost of products just kept getting bigger. So we found another pool store and were told to get a good algaecide, clean everything and shock the heck out of it. We looked at tons of algaecides, read reviews and my husband finally found this algaecide on Amazon. We added the initial dosage, 6oz for our 15,000 gallon pool than burshed down the pool and ran the pool pump for 24hrs. The next day we sprayed the pool filters clean and soaked them in a large tub of water with a half bag of Burn out 73, removed vacuum, hoses and leaf basket scrubbed them clean and soaked in the Burn out 73 shock water also for about 6hrs. Sprayed everything off again and hooked it all back up. Added 6 bags of the burnout 73 to the pool and ran the pump another 24hrs. The next day we put a pool RX in the skimmer basket and returned to maintenance. It killed the algae and we haven't struggled since. We prep our pool for winter in Fall( Oct.) I clean the filters and add 4 bags of shock and the initial 6oz of this algaecide 1 day apart at night, run pump 4 to 6 hrs each night, add chlorine tabs as needed that's it. For Summer start up (end of Apr./ beginning of May) I clean filters and at night add 4 bags of shock and brush the pool, next day add the the initial 6oz of this algaecide, next day a new Pool RX in the skimmer basket and 4 chlorine tabs in float. Running pool pump 8hrs each night in the summer. I have had no algae issues for the last 4yrs. with this maintenance combination during the summer: 4 chlorine tabs in float, 2 bags of shock and 3oz of algaecide. I do this every other week 1 day apart between shock and algaecide, and of course 1 pool rx at beginning of summer in skimmer basket. I don't even do chemical testing anymore. I have clear, clean, blue pool. I use BioGuard burnout 73 shock. Which has 73= % of Calcium Hypochlorite in each bag. Pool filters need cleaning at least 2 more times each yr.( so usually Oct.,Jan., Apr.,July). This is for a 15,000 gallon pebble tek in ground pool. It might sound like a lot of work, but once you get the algae under control the maintenance is easy. We don't struggle, we're not throwing money away and we're not adding extra unnecessary chemicals.
