FC - 7 CYA - 60 pH - 7.4 I'm keeping the FC level at 7-9 for my pool, which has plaster surfacing and aging copper piping. The 60 CYA, along with a pH of 7.2-7.8 will keep the copper piping from eroding, according to the wisdom of this board. However, I have a little black algae I need to get...

After buying a nylon-bristle brush for the pool, I was told to brush in one direction. For example, brush down the walls and away. The idea was that brushing in the opposite direction could be hard on the plaster. I'm not sure if this is correct, but it's the guidance I've been following...

Through process of elimination, I think I have a few spots of black algae in the plaster. Questions: 1. In using a nylon brush for normal pool maintenance, I read that the brush should be used in one direction only and have followed those instructions. Does the same hold true for...

When the return pipe and suction pipe in the pool are separated by only 2-3 feet, is it still best practice to add chemicals in front of the return stream? I imagine it is, but I want to make sure there's no immediate circling back into the skimmer. The pipes used to be separated about 20...

FC - normally 5-7 CYA - 60 Next time I add a maintenance dose of Metal Magic, I'd like to lower the FC to the recommended 1-2 ppm and add Polyquat-60. I'm not sure of the sequencing and timing of this process. Yesterday, the FC was 7 and after the weekend, it will probably go to 5, which is...

Several months ago, following a sponge test, I used Metal Magic to help reduce the copper stains in our plaster-surfaced pool. At the time, due to carelessness, I didn't lower the FC to 1 or 2, but kept it at 4. Many stains were removed, but some light stains have returned. I don't think I...

I dropped a Vitamin C tablet in the pool on top of a small green stain. It turned black. I may have added fuel to the fire by putting a Tri-chlor tablet on it afterward as Tri-chlor has always been my go-to stain remover. My immediate goal is to get rid of this stain and I bought some Dry...

I have some organic stains that respond to chlorine pucks, and so have been superchlorinating the pool for about two weeks with liquid chlorine. The stains may have lightened a bit, but I'm not sure. FC - 9-12 during the superchlorination CYA - 40-50 The stains are about a year and a half...

PG and I are disagreeing on the pH level of pool. As a result, every visit he pours acid in the pool and when he leaves I undo what he did with Borax. This will be a temporary thing... Either we come to a resolution or we fire him. In the interim, however, I'm wondering if the borate levels...

I recently talked to a pool contractor and he said copper used to be the material of choice for skimmer and return pipes. But over time, they didn't last up under the chlorine and are now being replaced. We have copper pipes that are well past the normal lifespan (30 years) and are concerned...

I'm a new practitioner of BBB and am using the Taylor K-1000 and K-2006 test kits. I'm keeping the pool guy for awhile since I can't commit to maintaining the pool full time (work, travel, etc.). It's handy to have him around to vacuum, brush, clean the filter and so on. A major sticking...
