First test readings of season

[stma]

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

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.

Thanks Big Dave::: I think the science behind this was to get as much as you can BEFORE the flow dwindles to nothing, backwash and continue the process... I've been doing such since Friday and have seen a dramatic improvement, but in all honesty, I really was hoping to see alot more improvement into the 3rd day...
