I'm sure you all see a hundred threads like this every season, but here goes. We used to have a smaller Intex with a real pump attached, now we inherited a used regular 18x24. My pool is GREEN. And I mean full-on deep, visible only about 18" down nasty.
I've been fighting this thing for about a month! We had a crazy week and no one ran the pump back then for about three days and it started getting a green tinge to it. So I do the pH, shock it, etc. which usually does the trick sooner or later. About three weeks ago, hubby replaced the motor because it sounded like bearings were going bad. Then someone at our local shop, pretending to be more expert than us, told us the sand should be replaced several times a season so we did--to absolutely no benefit. My pH has been running high most of the month and has only come down below 7.8 in the last few days with me adding about 2 lbs. cheap Walmart pH reducer every other day. I'd been using liquid chlorine and the bags of hth super shock n swim weekly. I've been putting in the blue clarifier 2 oz. about once a week through this fiasco. I noticed about a week ago my CYA (on dipsticks) was zero, so bought some of the tabs for the floaters that are supposed to add stablilzer. I also added about 2# hth "conditioner and stabilizer" flakes twice in the last week. I should add that the hth stablizer didn't say anything about putting the flakes in a sock, as I'm seeing on the board, just to add to the skimmer. I'm finally getting what looks like about a 30 reading on the CYA (again, on dipsticks, I'm going to order a decent test kit this week). I actually got it un-green for about two days, but still very cloudy, then it went back to green. the pool has run 24/7 almost all month (in fact it feels a little hot today) I'm about to develop a drinking problem here.
The particulars: 10,000 gal AG 18x24x4. Hayward sand filter S166T , 1.5 hp pump (35 gal/min according to the site).
The psi on the filter is running 18, and when turned off only goes down to 9, not zero.
As of noon today, FC-5, pH-7.6, TA-120, CH-200, CYA-30 (I shocked again last night w/ one gal 10% chlorine)
Yesterday, FC-3, pH 7.6, TA-140 (that’s all I remember)--this was done with the cheap 4-way kit from the hardware store w liquids. It also said I needed to add 1.5 muriatic acid.
Two days ago, FC-3, pH 7.5, TA-200, CH-200 CYA-30
When hubby turned the filter to “recirculate†it got much more powerful than when set on “filterâ€.
This looks like a bubbling cauldron of gross, but couldn't get one without sky reflection, lol.
Here you see that it's only visible to about the second step (maybe 18" down)
Here, you can see that the little "window" on the side of the filter has a little sand in it, all the time. Don't remember this from years past--is this a problem?
Here's the pump/filter setup, I believe they're 1.5" hoses. Hubby was in process of re-leveling it when I took pics today.
