  • Backwashing my filter ~ Against the Law?!?
    Backwashing is the process in which used filter media (D.E. powder) and trapped dirt or contaminants, are flushed out of your Diatomaceous Earth pool filter. Backwashing a Sand filter does not flush out the sand, just the dirt trapped within the sand bed. Backwash water contains the same chemical properties of your pool water, plus all of the "stuff" that your filter has removed from your swimming pool. It is important to know and understand local backwashing laws and regulations so you can comply and do your part in keeping your community environmentally friendly.

  • How's Your Filter? The Trio - Part III
    So, what is Sanitation of pool water? According to Wikipedia swimming pool sanitation refers to both visual clarity and levels of microflora, such as bacteria and viruses in swimming pools. The goal of sanitation is to prevent the spread of diseases and pathogens between users. Unsanitized water may also support the growth of algae which will present as a greenish tinge initially, then if left unchecked may completely inhabit the pool water displaying a solid green murky appearance.

  • How's Your Filter? The Trio - Part II

    Today we look at Part II of the Trio, Circulation. It was pointed out last month that if you had the circulation of a rushing river, moving your water at say, 1,000 gallons per minute, you likely wouldn’t need filtration or sanitation. I guess algae can’t grow when it’s moving so fast. But our little pipes and little pumps just can’t handle 1,000 gallons per hour, can they?

  • How's Your Filter? The Trio - Part I

    I always like to use the analogy that - if you had a filter as “big as a house” you wouldn’t need worry about circulation and sanitation. Or – if you dumped in 5 gallons of bleach every few days, you wouldn’t need to filter or circulate much either. Or – imagine circulating your pool water so fast, like a rushing river – turning it over at a rate of 1,000 GPM (gallons per minute) that Sanitation (chlorine) and Filtration becomes unnecessary for clean and clear pool water.
