recently opened my pool for the season. The ORP sensor in my sense and dispense system was working great - about 2ppm free chlorine at 650mV. We had a power outage for about 8 hours and my whole house generator kicked in. When it runs the LED lights flicker as it's not perfectly 'clean'...

My pool is currently closed for winter (i'm in southern ontario, canada). I have a fair amount of algae building up on the floor and walls. There are still freezing temps at night (for at least a few more weeks) so i can't really turn on the pump / equipment. Should I add an algaecide / stir...

great. I had that problem on vinyl pools which is why i went with fiberglass at a large premium. Guess i'll need to figure out how to install waterline tiles. Thanks for your responses. Jack

Interesting. I have the exact same issue. After the first year with my pool I had zero fading when i dropped the water to winterize. this year i have ALOT of fading (it is, well was, a dark grey pool). I dropped my CYA this year to minimize impact on the ORP readings. Perhaps this IS the cause.

Hi, I had a leisurescapes fiberglass pool installed two years ago. Last year when i drained the pool down for winter, the fiberglass was uniform in color above and below the waterline. This year, there is major oxidation of the fiberglass below the waterline. I am methodical with my pool...

I have a hayward omnilogic system with sense and dispense using co2 for ph control. I run my VS pump at 40% 24/7, but it seems like there isn't enough mixing when it comes to PH. Basically, the ph will register high, co2 injection will kick on, but it stays on too long - When i increase pump...

Does ORP consider free/ combined chlorine? From what i've read, ORP is a better measure of sanitizer efficacy than free chlorine. My ORP is always above 650 so do I even need to be concerned about combined chlorine? Perhaps only when ORP cannot get above 650?

would a taylor K-1004 kit suffice? I don't want to drop $210 cdn plus shipping for a test kit. I can get the K-1004 for $50 plus s&h.

aquachek pro, and confirmed with a reagent test.

25ppm

TC- 2 FC - 2 PH- 7.5 Alk- 100

Had a new fiberglass pool installed last year. I have the hayward sense and dispense system. Pool doesn't get used alot, but I've been running now since April and don't have any / very little combined chlorine. I haven't shocked all year - do I need to? no chloramine smells either.

I am working on a similar issue. I can not figure out how to set a valve 'on' or 'off' (position a or b) using omnilogic. I'm able to select the valve in the feature config but can't find an option to set it on or off , or position a or b. There is nothing in the documentation and I can't...
