    New pool owner here; I've been binge watching pool videos for days and most of them have too few nuggets of good, concise information and too many cheap production flourishes. This video was so refreshing to watch. Great info, great on-camera presence, great audio and camera work, great editing. Head and shoulders above the rest. Well done.

    We had a 'toad strangler' of rain here in Florida at our house a couple years ago that dumped almost six inches in under an hour! The way our yard is in back, and with ground already saturated from prior rain, the mud came up OVER the edge of the deck, and INTO OUR POOL! And it was a LOT of mud. I fretted over this for a day and wondered what I was going to do. A friend told me to let the dirt all settle to the bottom, then, use a manual attachment sweeper, put filter on 'waste' and sweep it out. It worked great! Once it was about 95% clear of dirt, I put on filter, put in coagulant and then swept it again a few days later. The water was back to sparkling clean after about a week.

    I have owned my above ground pool with sand filter for the last 37 years, and NEVER have I known exactly how my filter works until NOW! Thank you for a VERY comprehensive narrative... I learned so much! This last filter was installed with the handle not having clearance to go completely around, which, had I known this, I would have had the installer move it. He told me it doesn't matter that I can't use the "recirculate" position... so I accepted it the way it was. Now I hear you say that it should NOT be that way! So now, I guess I can expect the pump to break sooner than it should because of his error!
    It's pretty bad when you can't trust an individual who is supposed to be a "professional" and know what the heck he is doing. I wish I'd seen this video YEARS AGO!! Once again, this video is better than any instruction manual. GREAT JOB, Mark!!!

    I started with zero knowledge about anything related to pools when I moved to a house with an inground vinyl pool about 7 months ago and it’s been a rough ride. I have spent an embarrassing amount of time trying to learn everything I can so that I can understand how the pool works, maintaining it, water chemistry, troubleshooting, etc. I have about 6 binders and 2 notebooks full of notes and I feel like I’ve been to a million sites, read a billion articles, & watched a trillion videos and out of it all - your vids I have seen so far are the best out there.
    I can’t wait to watch all your vids and to check out your website. I hope you know how super appreciated you are!!

    We just had a Hayward filter installed like in your video above because we needed a new pool heater and the installer said to backwash about once a month, yet you say much sooner. We have an inground fiberglass pool. I've read some comments below where installers seem to give differing opinions on other subjects, as well. I'm a bit confused on the backwashing timetable, but I think I'll listen to you as we have a Hayward, like I said. Love your concise info. VERY well made video! Thanks!!
