Detailed Product Description

Eclipse3 is an all-natural mineral treatment for pools, spas and hot tubs. Eclipse3 has been proven to perform extremely well in three main areas; it eliminates algae growth and reduces your use of chlorine, clarifies the water while maintaining a proper pH level, and can reduce your electrical operating costs by as much as 66%.

When used as directed, Eclipse3 helps pool and spa owners maintain a healthier, cleaner and more natural way of enjoying their investment and leisure time.

Eclipse3 Features:

  • 4 Kg Container
  • offers pool and spa owners a mineral-based, natural way to combat algae and bacteria growth
  • eliminates the tedious daily routine usually associated with pool and spa maintenance
  • allows pool and spa owners to add less chlorine and bromine and still maintain crystal clear water in their pool or spa reduces the need for vacuuming
  • saves on pool and spa chemical costs – by as much as 60%
  • saves on electrical costs by as much as 66 % - you only need run your pump and filtration system for as little as 8 hours a day
  • eliminates worries about strong chemical odors, irritation of the skin and eyes, bleaching of hair and is environmentally-friendly
  • is safe for pool liners and has no erosion effects on filtration system parts

Directions for use:

First determine pool volume:

Circular = Diameter x Diameter x Avg. depth x 786

Oval = Max Length x Max Width x Avg. depth x 786

Free form = Surface Sq. m. x Avg. depth x 1000

Rectangle or square = Length x Width x Avg. depth x 1000

For start-up:

  • Shock treat pool with chlorine or bromine following the supplier's recommended label rate
  • Balance water alkalinity in the range of 80-150 ppm
  • Maintain ph between 7.2 and 7.6
  • Add 57g of eclipse3 per 4000L of pool water; use measurring cup provided in pail
  • After treatment run filtration system continuously for 48 hours; backwash at 12 hour intervals
  • Vacuum after 24 hours to remove any sediment collected by eclipse3
  • One week after treatment, continue using eclipse3 as directed by the weekly applications instructions

Weekly Application: Copper levels should be 0.5-1ppm. When copper level drops below 0.5 , eclipse3 must be added (3.5g per 1000) until the required concentration is obtained. Once the required level is reached, run filtration system for 8 hours daily.


1. ONLY use measuring cup provided with eclipse3

2. Distribute eclipse3 close to the surface near discharge jets to reduce the risk of staining accessory surfaces

3. Daily monitoring of chlorine/bromine may be needed during periods of heavy traffic and high temperature

Customer Reviews

This stuff is amazing. Get your ph, alkalinity and chlorine levels in the right range. Toss Eclipse 3 in the pool as directed and watch that green water you've been unable to get clear turn blue in a few hours. I'm truly amazed. I spent all of last summer battling green algae and nothing seemed to kill it including shock and algecide. I was going thorough chemicals like crazy. Now the water is balanced and blue. I can't believe what a difference this product made.

This stuff is incredible! For years I waited to see if I was going to get algae. Never really saw it until I took out my stairs at end of season. It was covered on the back and inside the stairs. I have stairs, not a ladder. Then to clean it was really tough. In 2019 I used this for the first time. Just the weekly treatment. At end of year. NO ALGAE on the stairs! The water has been great. Just add it to the jet stream and let it do it's thing. 1 cup. That's it! The company even tells me it can be used in a hot tub if you get algae in a hot tub. Same product, 2 pools. Now that's the way to go.
