The cell and cable are brand new! The store people suggested that "The Digital Nano likes the salt level to be a little high, so top that off and see if it improves." So I did that - Salt level is now a perfect 3000 ppm but it still cuts out. Tech guy comes Monday afternoon to check the...

I had trouble with mine not priming once, and it turned out that the main O-ring for the pre-pump basket (a last-chance leaf catcher attached to the pump) was missing. The last time I had opened it, the ring momentarily stuck to the underside of the lid, then dropped into the basket. I did...

Next day, things should have mixed (plus a lot of rain). So now I have FC=5.2 OK, pH=7.5 OK, Salt=2800 Better, TA=70 OK, CH=250, CYA=50 giving a CSI of -0.4, which is worse. If I was to goose the CH up to 400 (which is the center of the good range according to the TFP defaults) and leave...

I always get the pH correct before doing anything else. pH affects a lot of other things.

I have a different model SWG, but it has a calibration setting where you can correct it to match an external reference, which would be what your test kit says. Maybe yours has this?

Using just my numbers, which was before applying any corrective additives, I get a CSI of -0.01 which is not bad at all. I will test again in the morning after everything has mixed in. Of course, it just started raining cats and dogs so who knows... There is a Lowe's just 4 miles from my...

PoolMath (using the TFP defaults) suggested CH limits of 350-450. Pool store says 250-400. I tested it as 220, they tested as 250. Quite different opinions on what the correct range is. I measured TA 80, they said 95. PoolMath range is 60-80, store's range is a much looser 80-120! I...

Test results pH=7.8, Acid demand says add 1.15 pt HCl. FC=8 (because of the gallon of Cl I put in yetserday) CYA=40 (will add some), no Combined Cl. TA=80 CH=220, should be higher Salt now down to 2200, buying 2 bags. Those are all with my new Taylor test kit. Now I am off to the pool store...

My pool light is the usual sort of installation, about 10 inches in diameter and secured with a single screw at the top. The trouble is that all of the weight of the fixture is back behind the lens, and the whole thing is supported by the plastic ring around the lens, so it swings forward...

After 5 years of operation, I replaced the cell and cable on my Digial Nano. It was getting constant "Low volts" warnings and not putting out any Chlorine. Multiple washings had no permanent effect, and the lady at the pool store said that these things do have a limited lifetime. Ok. (But I...

I found the source of my problem with timers. My old pump was a simple dual-speed one with no timer, so it was wired into the same mechanical switch as everything else. When the Intelliflow was put in, it was wired direct to the circuit breaker, bypassing the timer. But the SWG and solar...

The Pinch-a-Penny near me sells both. I believe they told me that the muriatic is about twice the strength of the sulphuric. Muriatic acid is also known as Hydrochloric Acid, HCl. It seems to me that using an acid with Chlorine in it would be more compatible with pool chemistry. Chemistry...

Taylor K-2006 is supposed to arrive 31-May and I will test the CYA then. (Amazon was out of the TF-100) Thanks for the run-time chart - that should help me zero in the settings as I wean myself from depending on Pinch-a-penny.

I have just reprogrammed the Intelliflow to operate at 850 RPM only between the hours of 8am and 6pm, at least for the summer. The SWG will shut itself automatically when the flow stops, so that is OK. The solar controller (a Pentair Solartouch) also always has power applied. When it sees an...

I have ordered a new Taylor 2006 test kit, plus the kit for testing salt levels, which should arrive next week. The house roofline does not run East-West, but North-South. To get sufficient exposure and make up for cosine losses, they had to put panels on both the east and west facing parts of...

I have a Pentair intelliflow pump and also have it set to run 24 hours per day at a low speed (750 RPM) that keeps the SWG happy. When the rooftop solar system decides that it is worthwhile turning on, it commands the pump to a higher speed, currently set to about 2300 RPM and then it movies...
