Cloudy water is it my filter?

[Skymarc]

These numbers are from the pool store lab test, they are good. I take ph and chlorine test only with a small drop tester. I have a k2006 on order.

I only added liquid chlorine 12% (im on my 2nd 55 gals drum), some Borox to push ph up also some copper sulphate 2 weeks ago.

Not sure on the sand filter, I had the same problem 2 years ago, dealer said the sand was too coarse, he sold me a finer sand and its not better. I stop the pump last night and the pool was clearer this morning I was starting to see the bottom. I could see some dust in the bottom so I put in the Dolphin robot and it made it cloudy with the cleaning. I restarted the pump this morning and its cloudy again.

I will get some stabilizer and will try to find some DE sand to do your test.

My sand filter is a 30" size with sand about 10" -12" down from the top, is this too low? Pump is a 1.5 hp Pentair.

I will probably take the sand filter appart to see if I find anything wrong. What do you think of Zeobrite sand media?

Is your sand "pool sand." It makes a difference. Try the DE test. (By the way, DE is not sand. You should be able to find it at your pool store.)

Check your manual for how much sand your filter needs. It may be that you are low and need to top it off. The consensus around here seems to be that most people don't think Zeobrite is worth it.

Glad you ordered a K2006. Unfortunately, most pool store testing isn't accurate.

Im pretty sure its pool sand as it was sold by a pool shop. I will try to find some DE.
Just got my K2006 test kit. Will test tomorrow.

I added some Stabilizer and Borox. I did my first test with my k2006. PH is still low, could the Stabilizer put the PH down?
Water is still cloudy, need to find the problem with the filter.

PH 7.0
FC 7.5
CC 0.5
TA 80
CA 200
CYA 50

Stabilizer doesn't really affect pH too much. Go ahead and add some more Borax to try and bump it up.

Just want to update.

I took my sand filter apart, found out that the installer 7 years ago had use a 1.1/4 pipe standout on a 2" filter head. Spyders were ok. No wonder it wouldn't filter. Glued in an adapter and pipe to 2" and reinstall my sand and filter head. Big job on a 30" filter.

Within 4 days the pool as clear up perfectly.

Added 2 box of borax and 1 box of sod bicarb.
Added 3 x 2 kgs of stabilizer and now the pool is clear and uses very little chlorine.

Here are my numbers, from the pool shop test but mine are basically the same.
FC 3
TC 3
PH 7.5
TA 140
CH 220
CYA 70
Borate 30
Copper 0.5

I took a sample of water to my pool shop and they gave me a perfect water balance certificate !
Thanks for the help.

Now I got a few stains on the liner, whats the best product to clean does?
