First test readings of season

[michael3]

I just vacuumed blind lol, I lost suction trying to get vac hooked up, I turned off pump to let it reprime and my pressure that had built to 17 went back to 10 with a good suction on vac head. It didn't take long for it to shoot back up to 17. I don't think I have much debri at all on bottom, I got nothing. I backwashed and recoated my DE. Slowly but surely it is clearing, my chlorine is holding overnight and I had a 4.5 drop during a very hot sunny day

SOON we will no longer be the laughing-stock(s) of our neighborhood(s) ! Actually, some of the neighbors are coming over and giving me Cold Coronas while I drudge through this process !! I think they feel sorry for me : >

Lol, soon isn't the word for me. This is gonna take some time, I add enough DE to bump my pressure up 1-2 psi then it seems like it takes forever for the pressure to rise enough to backwash, makes you want to throw more DE at it but I understand that wont make it filter any faster. I also remember Ben saying some of the "fog" is to fine for even DE. Sigh....

Like I had mentioned, I figured out my little sand filter will "take 4.5 oz of DE (which looks to be about 2 cups+) This much (according to Ben) should coat the entire top bed of the sand... it lasts for hours and hours before jumping psi..

But all day yesterday, i experimented with all different amounts of DE, as high as up to a double dosage (9oz)... That dose clogged things up within 30 minutes or so..... I simply backwashed for a few seconds and started again...God knows I have enough of this powder (10lbs)...

Personally, I made HUGE advances today......and for once in my life, I'm gonna have to be patient and hopefully things will De-Fog...! I'll see if I can post some pictures..

Lol, making progress or one to many free coronas lol. I tried about a total of a cup in about a 30 minute span and got close to a 5psi jump then it slowly rose, when I add enough to get a 1-2 rise it doesn't seem to want to increase

[stma]

Im wondering if I dose a heavy amount (2+ Cups) let the pressure increase THEN keep it there overnite.... I know the pressure out of the return wont be strong, hence the pool will be slow to re-circulate... but with that much DE coating the filter surface, I would ASSume I'd be catching the tiniest of particles....???

At the end of the day, it's all a crap shoot..

You may but not very many of them. If the flow is too low there just won't be much water flowing through to clean. Moderation in all things.
