Hi, this is my very first post.
Note: I'm in the middle of summer where I live
The problem: Cloudy pool water (drain cover is barely visible).
Test results:
pH: 7.4
Total Chlorine: 15
The thing is, I can't get a proper test kit since they don't sell those in my country. I'm not even sure that the TC reading is right. I've got some strips that test TA but they're a year old and read 70-80, and CYA at around 20 but I'm quite sure it's way higher.
Description: For the past 2 seasons, the water seems to get cloudy after a while, even though pH is corrected every three days (it tends to rise quite a bit) and I add chlorine every 2 days (sometimes Dichlor, sometimes Liquid Chlorine). A litlle bit of algae shows on the bottom at the sides and when it does I add like 4 times the dose of chlorine and brush.
The main issue is that every time I get cloudy water I run the sand filter for about 16 hours and the water doesn't get even slightly more clear. And the filter doesn't seem to clog up after a while, the pressure remains constant. What is more, I don't think the filter did any acceptable filtering since the pool was built 5 years ago. The only way of clearing up the pool is by using flocculants which take 3 days to work.
I've opened the filter to inspect the sand and though it's roughness and level seemed fine, it was not flat inside the filter: it was uneven and cone-shaped around the main pipe.
All this led to the suspicion of channeling since (see my signature) a bit of investigation made me notice that the pump may be oversized for the filter's capacity.
Getting a new filter (bigger one) is quite expensive, and pool professionals are such morons over here (they just tell you to check the pH, they don't ever question the filter's efficiency or actual state).
Is there any way to be sure that the filter is the culprit? Is it? I'm really fed up with this and annoyed too, since I read in every website that sand filters should be able to get the water crystal clear.
Thanks for reading.
