I have the same colored stains in the deepend. They tested negative with the Vit C tabs. Now what?

Being that our pool water comes straight from the well, there has always been a less than perfect feel to it. Soft and or silky have never been adjectives used to describe the water. Although the majority of the pool's chemistry is always great, CH of 310 can't help the feel at all (right?)...

I have a Hayward wet niche fixture that for the last few years, turns itself off after being lit of about 10 min. It cools and turns back on for another 10 min or so and repeats :rant: . I looked at the fixture before replacing the bulb a few years ago and was unable to determine what wattage...

I was maintaining a CYA of 50 last year. The pool level was dropped 18" for closing last fall and refilled to operating depth in late April. I assumed my CYA would be at least close to the ballpark but couldn't test since my TF100 kit was depleted of reagent. I ordered a new TF100 a few days...

Temp 68F, FC-5.5, CC-0.5, pH-7.3,T/A-300,CH-330,CYA-<20 (added enough to get 50 once dissolved) metal sequestrant used to treat 40k as i was filling. Been backwashing the filter as needed. Pump running 24/7 The water has a blue/green tint with a slight haze. Since fill was complete...

Where would you folks set your CYA level in a newly filled pool, and what product do you suggest I use? I am using BBB so i won't be getting any CYA from pucks. Thanks!

Greetings all! I hope everyone had a great off-season. We had a auto cover installed last year, but used the mesh cover for this past winter because the liner was diagnosed with multiple holes. I didn't want to risk having the water level drop and subject our new $10K cover to snow weight...

Just wondering if anyone has roughly the same cover set up as we do. We just spent about 10K on a retro-fit Coverstar Eclipse auto cover ( The 10K is with me doing the concrete work :roll: ). The cover measures 24.5x40 feet...wider than most auto covers for a 20x40' inground. The reason for...

I have a 500w niche lamp in the deep end of the pool. I replaced the lamp when I opened the pool this spring. I haven't had the light on very much until just recently as we are spending more time in the pool after dark. The light will stay lit for 30-40min, spontaneously turn off for 10 min...

I've been admin on a couple boards using php....I know how it can be getting your saved database transferred to an updated php version. Good job! :wink:

I have iron stained calcium deposits on the vinyl liner of the pool. They are heaviest on the slope leading to the deep end but also are on the walls of the deep end. The are not covering huge areas but there are a lot of small deposits throughout making it not look bad. I tested the stuff by...

Over the last couple days I've been going through the proceedure for lowering the high TA in the pool with a lot of success. My fill water comes from our well and after testing it, I came to realize why my TA and CH in the pool are so high. The well water has a pH of 7.0, TA of 400, and a CH of...

Okay....I've been trying to rid my otherwise clear pool of this stuff: I assumed it's algae, but now think it may be scaling. I shocked the pool to an FC of 28 for the last 24hrs. I had the FC up to 16 for 24hrs before that. I tryed to brush the pool this morning and the stains/algae...

Just tested with the TF-100 kit that arrived this afternoon. Here's the results: FC-3 CC-1 TC-4 pH-7.5 T/A-310 CH-190 CYA-48 Temp-80F This is my first pool. We bought this home last Nov. I opened the pool myself and did as best i could to get the chemistry balanced with the tests I...
