I’m not sure why I confused by this at the moment but but when I use pool math and then look at Effects of Adding, my brain is not comprehending. Why am i not holding chlorine? I realize my combined his high. I just added stabilizer yesterday and maybe bleach too soon after? Should I do anything...

Hi folks. I know there are no short cuts, but I’m going to try to take one here. Since opening I have had debris back in the pool. (There is no way that many gnats accumulate on the bottom over night.) I know what to check — filter grids or multiport. But it’s the time, I don’t have time to...

I am backwashing my de filter and realized no de powder is coming out. Water was clear from the start. I have a multiport valve on a hayward 4820. And yes, I know there was powder put in. Pool has been great. Last backwash was maybe beginning of June. Return flow was low yesterday, pressure was...

Hi everyone. Just got through a successful SLAM opening due to winter cover failure (nasty) and am ready to tweak my balance. Ph is at 7.2 and alk @ 71. Please advise because I got myself confused (easily done these days). Other than that I just have to bump up my cya (at 5) and FC. thank you!

Is it common for a de filter to not remove white powder from dead algae? I had a very old Hayward perflex which didn’t seem to be doing it’s job all summer. As opposed to begin checking and replacing parts, I opted to replace the filter and yesterday installed a Hayward 4820. Before replacing I...

Can I use a Hayward Pro Grid de4820 on an above ground pool? I am not familiar with the grids and this filter is often described as an inground pool filter. I have a 27’ agp, 1hp single speed pump, currently using OLD Hayward ec60 which isn’t quite doing it’s job this summer. I’m not sure it’s...

HI. I just took a 27' round scumming green pool to clear in 3 days. I feel quite successful. I had to switch to an inherited Perflex DE filter last year and have a question regarding vacuuming. With a large amount dead algae on the bottom of the pool, I feel I should vacuum to waste but it...

I'm seeking opinions. Last year we installed a 27'above ground pool but didn't get to it's surround or landscaping. We are in the midst of installing a deck and CANNOT WAIT for this to be done. So I have the area right against the pool and the areas under the deck and walkway that will...

Pump basket is full of air and air bubbles in return. Poured hose over basket housing and bubbles stopped so I figured - replace o ring on lid...nope. I can tell there is a lot of air in the de filter tank yet when I open bleeder, water does come out. - - - Updated - - - I can actually hear...

Hello! Happy Spring. This weekend we are moving a 3/4 surround deck from a neighbor's (no longer existing) 30' pool to our new 27' pool. Any tips or useful info on making the conversion would be appreciated!

I am new to de filters. I have just fixed a leak (hopefully), so note - air was being drawn. My concern is, as I've opened and closed this thing 5 times, I've noticed the fingers do not seem to be coated. There is just a pile of powder at the base of the filter. Is this normal? I had taken the...

Just opened pool. Need to begin balancing. At this point no stabilizer present. I have in my possession a huge bucket of 3" tablets and another of granular (dichlor). Is it possible to use these to start? Wondering if it will raise cya enough while maintaining fc. I hate to waste them.

Working through the world's longest pool erection - -If Kim or Casey are there ~ still not swimming =( Our 27' round walls were set up for the umpteenth time and the pool was perfectly round and staked. 12 hours of beating winds and rain and the east side has 3 or 4 radius measurements that...

Ok. I am progressing on the world's longest pool erection. At this point the walls are up (for the 4th time, yes, 4th), sand is being meticulously leveled....BUT some of the radius measurements from uprights to center are short. Most are 13'5" to 13' 5 1/2" but 3 or 4 are measuring short with...

What are the advantages of prepping your sand bottom before or after the walls are up? I've seen it done both ways.

Hello. We will , hopefully be constructing our "new to us" 27' round pool tomorrow. Tracks have been leveled and laid (for the third time) and looking forward to things going better this time around. If anyone happens to have any tips on keeping track shape during wall installation, please...
