    No Combined Chlorine, FC 7-9, CYA 35? Taylor test vs pool store?

    Thank you. Regarding the chlorine: So how do I get some CC instead of just free chlorine? I thought that the equilibrium will have the CYA will "Lock" a certain amount of the available chlorine depending on the amount of CYA, so shouldn't some of the FC be held by the CYA? Regarding the...

    No Combined Chlorine, FC 7-9, CYA 35? Taylor test vs pool store?

    Hi! I took some pool water to test at my local store and the numbers came back puzzling to me, so I tested at home with the Taylor kit and I'm still unsure I fully understand. If I have a decent CYA, shouldn't the there automatically be combined chlorine if the free chlorine is over a certain...

    Hayward Heater transformer failed - H300ed1?

    Thanks! I swapped it out with the amazon one I listed and it fired up nicely! Hopefully, I get another few years out of it. Do I need hi-temp or damp-rated wire nuts for the connections inside the heater?

    Hayward Heater transformer failed - H300ed1?

    Followup Questions I had when looking for transformers: Why is there such a dramatic price difference when I look up transformers with the same specs, vs when I look for Hayward heater transformers? Class II transformer, 40VA, 120/240 primary, 24v secondary For example this $20 one vs this...

    Hayward Heater transformer failed - H300ed1?

    Hi! This forum has been excellent at helping me get the old pool I got last season up and running, and I was hoping I could breath some life back into my old gas pool heater before it truly bites the dust. It's a Natural Gas Hayward H300-ED1, configured to use 120v. It's on a 20A Breaker. See...

    Can't seem to prime my pump, water just leaves the basket.

    Interestingly, I let it sit for about an hour and tried to start it up again and it worked just fine, pulling in water in about 10 seconds. I assume it is somehow related to the cover but time and more experimentation will tell. I'll keep and eye on it and see if it loses the prime when the...

    Can't seem to prime my pump, water just leaves the basket.

    Interesting! How would I use this? Does it go in the skimmer return with a garden hose and I use that to force water all the way to the pump?

    Can't seem to prime my pump, water just leaves the basket.

    Hi! I have an old Pentair challenger "Self-priming" pump that we just replaced the motor on. The pool guy installed the motor and primed the pump last week. Today I opened the pump filter basket to clean it and I cannot for the life of me figure out how to get it primed again. Here's what...

    Black staining on new plaster upon adding chlorine - what is it?

    I don't think they did. The light still works, but it may well be ruined. unfortunately, it's an obsolete Anthony light that I can't easily replace without replastering that section of the pool, which will be frustrating as we just plastered it. I still need to give the stain a Vitamin C scrub...

    Black staining on new plaster upon adding chlorine - what is it?

    I'll try that. any way to make it stop after if it is Iron? Or do I need to find a way to replace the whole housing?

    Black staining on new plaster upon adding chlorine - what is it?

    Hi! We recently got our pool replastered with Diamond Brite (Oyster Quartz). After an acid-hot start, we balanced the pool water and added chlorine. The water was acidic for about a week as the pool guy ghosted us & we had to find a new person. The pool guy added a lot of chlorine with pucks...
