Cloudy water

[jbalcorn]

IG Vinyl 25,000 Gal pool
New filter last year.
New heater last year

Water got a little away from me: Ph too high (8+), and some vague green cloudiness. (I usually like to keep my ph a little high - 7.6-7.8.) Chlorine was all gone.

Got ph down quick with muriatic acid - now at 7.4. Shocked the pool 2 days ago (TC up to 15), and now water is cloudy, but white. Filter seems to be pumping plenty of water, and I've backwashed several times. Clorine level still very high from the shock - weather here is hot and has been cloudy, but is sunny today.

Numbers from this morning:
FC: 11
CC: 0
Ph: 7.4
CYA: 50
Alk: 160
Temp: 78

Last year, I had my CYA lower, my ph higher and although I had to add bleach a lot, the water was crystal clear.

Any idea where the cloudiness is coming from? I thought it might be dead algae, but the filter should have taken care of that, right?

Keep at it. It can sometimes take awhile to filter out dead algae. Are you running your pump 24/7? If not, do so while you are trying to clear the water.

[jbalcorn]

I run it 24/7 all season.

I guess It just required patience.

Is dead algae the most likely source of the white cloudiness? It's no better today, if anything, it might be a little worse. I did a quick check with my OTO tester:

TC: 4
Ph: 7.4

It rained hard this morning.

I've backwashed the filter to make sure it's running at it's best multiple times. It's running at 24 PSI, which is exactly where it was when we installed it. When it gets dirty, it gets up to 30psi. The filter baskets are all clear. I had the eyelets pointing up before, I pointed them down to make sure that the water flow got all the water through the filter.

I shocked the pool Thursday evening to kill the algae - it's been more than 2 days of constant filtering. Is it really expected to take this long to start clearing it up?

Try putting a stocking inside the return basket, I did and had alot of pollen in the water.

You could try a clarifier. It's a liquid binder designed to bind particles in the water to one another, making them bigger, ie: big enough to get caught in your filter. A filter sock will not work, as anything small enough to get thru your filter, will get thru the sock (easily). When I had an algae bloom last year, I had to vacuum up all the dead algae, as it would tend to sit on the bottom and not get circulated in my 24' AG enough to get into the skimmer. What type of filter do you have?

What did you use to shock with? You don't give a hardness level, but with high pH and alk, if you used cal-hypo to shock and have a high hardness level, it may very well be a calcium cloud.
