My pool has been driving me crazy this year. I started the TFPC (ABC) method in July of 2013. After getting my high CYA level (300 plus) down and performing the firs SLAM, the pool was a breeze to maintain. I kept my FC around 3-4, occasionally it would dip as low as 2.0 but never saw algae...

Here are the measurables as of this morning: FC: 2.0 CC: 0.0 pH: 7.7 TA: 65 CH: 100 CYA: <25 I just completed a SLAM 7/18/16 - 7/22/16 which consumed well over 10 gallons of 10% bleach. The OCLT only had 0.4 ppm loss, so not like it was marginal or anything. I know the CYA is low and I have...

Can't tell for sure if this is 7.5 or 7.7. In the picture it looks like 7.7 to me, in reality it is much harder to determine because it is much more red than pink.

I am planning to remove portions of an 18 inch wall that is only 6 ft away from my pool. We will need to cut the wall in several places and I was wondering if the dust from cutting the block and stucco is very bad for my pool chemistry and filtration. I just got a new liner and fresh water in...

I need to raise my pH and TA a little bit: pH is 7.4 TA is 50ppm I am not clear on what I have in this bag labeled Sodium Hydrogen Carbonate I think I answered my own question: on the other side of the brown bag which I hadn't looked at it also says: Alkalinity Increaser. There is a chart...

For a year all seemed to make sense and my water was crystal clear with no signs of green. Then I saw the slightest traces of green algae and I performed a full battery of tests which is when I realized that my CYA level had gone practically to Zero. In the past 4 months I have had to SLAM...

I need to fix with as low cost as possible. Have time to perform labor as I just got laid off. Below is the label from the pump motor. The pump is a Hayward SP2710X15. Can I downsize the motor to a 1 HP (currently it's a 1.5 HP) to save some cost? I have researched buying a bearing kit but...

My pool has been sparkling clear for almost a full year and it still is. I discovered a tiny amount of visible algae on the white endcaps on my ladder and some around the stair way opening. I also removed my light and found small amounts of algae there. As a precaution I started SLAMMING. I...

Amazing thing, a little over a year ago (7/19/13) my CYA was over 200, maybe even 300. I stopped using pucks and started the BBB method. After months I finally got it into the range I wanted, about 50 then into the 40s and 30s. Months went by and I didn't give it much attention. Over the...

Back on July 6th my pool would have measured something like this: (didn't own a real test kit, that's why I say would have measured) FC - 3.0 CC - 0.5 pH - 6.8 TA - 20 CH - 130 CYA - 250 I was still listening to pool stores a few days earlier and they told me to add 33 lbs of Baking Soda. I...

I know this seems like a very elementary question but I have searched and not found any recommendations on this site. As a reformed Puck user I have not been schooled in the techniques of adding liquid chlorine. I have been taking my 2.5 gal jugs and walking the perimeter of the pool with...

I started to see algea and initiated the SLAM earlier this morning. I know why I got this little bloom, it was my fault. I've been working on lowering CYA and with the drain, refill and high CYA I haven't maintained a high enough FC level. I did get my CYA down near 50 today, :party...

Thanks to my extensive use of chlorine pucks from before my enlightenment, my CYA is 160. I have been slowly getting it down, it was probably in the 250-275 range. I had very low pH and TA also and got that corrected, in the meantime my pH has risen beyond my target (it's 8.0 now and TA is...

Since I need to dilute my CYA infested pool, I am draining down every day to below the skimmer and I am filtering through the main drain only. I am doing it gradually because I want to use rain water (I diverted one of my gutters) which has a pH of ~7.4 rather than my tap water (pH <6.8)...

FC - 2.0 CC - Not tested pH - ?? It is less than 6.8 TA - 120 CH - 100 pool store measured 10 days ago CYA - 100 pool store measured 10 days ago Borates - have not used yet I have been trying to balance my pool for about 10 days now. Just discovered this forum. I don't have the full test...

Hi everyone, been lurking on this site while troubleshooting my pool for the past week or so. Great source of know-how. I live in Central Florida and I have a vinyl liner pool with a Hayward DE 3600 filter and a 1.5 hp Hayward pump.
