    Switching to Z-Media in Sand Filter

    Good morning. I am planning on using a form of Z-Media this year once I open the pool. I see that you have to backwash the filter multiple times once adding the Z-Media to remove the dust, etc. My question is this....generally when I open the pool I have a bit of algae growth. If I am backwashing, won't this be drawing "dirty" water from the pool, causing difficulty to tell when the site glass is clear? One point I might add is that I do not currently have any sand in my filter. I removed it when I closed the pool last year.

    Thanks.
    Mark

    Welcome, Mark!

    Unless your water is a viscous sludge, I doubt you'll even see the tint through the sight glass.

    Before you go spending big bucks on sand replacements, take a minute to use the search box up in the right corner for Zeosand or Zeolite and see what others have experienced. Also worth a look: My findings on how not all sand is created equal

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    I agree with Richard, do a little more research before you spend the bucks to Z-Media.

    Generally what people think of as "filter" problems end up being chemistry problems.

    Have you been following TFP guidelines? If not, as part of your research check,out Pool school and check out the FC/CYA relationship as well as information on stabilized chlorine vs non-stabilized.

    In general we feel that sand almost never needs to be replaced and the few times it does is likely due to use of various magic in a bottle concoctions or Baqua-Slime when transitioning off of a baqua pool.

    I've read a lot of online complaints about Z-media...be cautious.

    I did have glass media in the last house/pool I owned and even though it's not as popular as sand in this
    forum it worked very well for me at the time.
