  • Treatment of Black Algae in Pools

    black algae in my pool!When I was growing up, in Central California, we had a bad case of Black Algae. It was my job to dive in the pool, first with a putty knife and later using a chlorine tablet, and while holding my breath, scrape off as many black algae "heads" as possible. "Black Algae - it's like Herpes, once you get it, you've got it forever". Not necessarily true, I found out much later in life.

  • Treatment of Yellow Algae in Pools
    yellow algae in swimming poolsAlso known as Mustard Algae, Yellow algae is a unique type of algae. The most distinctive distinction between other colors of algae, blue, blue-green, or black algae, Yellow algae forms small colonies in the uneven surfaces of your pool. Pits or crevices in plaster, or dips and dirty areas on a pool liner create a safe harbor for this particular strain of pool algae.

  • Help! I can't get my pool to clear!
    Rob Cox
    cloudy hazy pool waterIt's a common question this time of year. We see it in our forums, emails, chats and other areas where we answer pool technical questions. It usually goes something like this: "I have done everything, and I mean e v e r y-thing to this pool. Balanced it, Cleaned it, Shocked it - even running the filter 24/7 and the darn thing won't clear up - Help!"

  • Phosphates & Nitrates in Pools
    Rob Cox
    phophates and nitratesIn swimming pools, our main goal is to keep eutrophication to a minimum. We don't want to see any plant life growing - unless you are operating a "natural pool", so it makes sense to keep levels of Phosphates and Nitrates to a minimum in swimming pools.

  • Swimming Pool Algae ~ Identify & Destroy
    green poolsThe key to algae control, is prevention. If algae doesn’t get started, it won’t be an issue. My number one rule is chlorine. Chlorine to prevent the algae from starting, and if it does get started, chlorine to kill it. In most cases, it is very easy to prevent algae. Keep the chlorine level at 1-3 ppm at all times, keep the pH between 7.2 and 7.6 and shock the pool every other week.

  • Algae - the many hues and colors
    Algae, bacteria and mold can present itself in your swimming pool in many forms and colors. Restoring your pool and getting back that healthy crystal clear blue water can sometimes become a task. The best remedy is of course prevention. Continually monitoring and adjusting your water chemistry is a must - but unfortunately an algae bloom can occur almost overnight.

  • Yikes! My Pool Water is Green!

    The green pool. Not very pleasant. Pools turn green from green algae. There is only one sure way to knock the green from a pool. Chlorine. And make sure it’s enough chlorine. Many times we hear, “But I put four bags of shock in the pool, and it’s still green” Well, four bags of shock should kill algae in a pool under 20,000 gallons, If they are added at once, not a bag at a time. The key to getting rid of algae, is “super chlorination.”
