My pool light no longer works and requires replacing. I have verified power up to the junction box so I am pretty sure it is the light. My light is operated by a single wall switch. Does anyone have any experience with the Jandy multicolor LED lights? I am considering the Jandy CPHVRGBWS30. It...

Thanks for all the information. Do you see a difference in the polyfil absorption of the iron at different water temperatures? In other words, is it better or worse when the water is say 80-85 vs 60-70?

Thanks! Do you know what the chemical interaction is whereby the polyfil absorbs the iron? Just curious.

Also, when you refer to polyfil, are you referring to white fluffy stuff like what is used in stuffing pillows?

With the iron in solution by adding ascorbic acid, will the Curator packs in the skimmer basket and pump basket be effective in removing the iron from the water?

Hello Allen, Thanks for your reply. My mistake: when I said calcium tablets, I meant to say vitamin C tablets! Per your suggestion, I applied another "good dose" of vitamin C tablets on the staining and lo and behold, the stains would disappear, confirming iron. Any idea why the iron stains...

My pool is slowly developing some staining and I am baffled what it is and how to address it. See the attached photo with the developing brown staining along the edges of the sun deck and steps. I have applied calcium tablets directly to the area - no effect - so not iron. I have applied liquid...

Thanks to all who have assisted me. Here is an update. I soaked the cartridges in TSP for 18 hours at a mixture of 1 cup per 5 gallons fresh water, then I rinsed them off. Then I soaked then in muriatic acid for 18 hours at a mixture of about 40 to 1 in fresh water. They came out pretty clean...

I completed an 18 hour soak with my cartridges using TSP (6 cups in 30 gallons of water), then throughly rinsed them off. Upon startup, the pressure as 19 psi - down 3 from 22 psi but well above the previous clean state of 12-14 psi. After running the system for about 8 hours, psi has increased...

Hi Jim, Unfortunately, 6 years ago when the pool was built, I never ran the brand new system without the cartridges installed to check for the initial baseline pressure. It is interesting as you say, the pressure now (12-14 psi) is the same as with perfectly clean filters. I agree, I was...

No, I have not used floc. But last September, I did the protocol for removing iron staining. The procedure worked great. I did not notice any pressure increase following this. Ascorbic Acid Treatment - Further Reading I will try the TSP approach. Any idea how much TSP to use in a bathtub? My...

Here is an update. I removed the cartridges, put everything back together and restarted the (single speed) pump. Pressure was 12-14 psi. In the past, when my filters were cleaned, the pressure would be the same. Again, putting the cartridges back in, the pressure is back up to 20-22 psi, which...

Mr. Rocket and Jim, Thanks for the suggestion to remove the cartridges and see what pressure I get when running the pump. I will try that and will report back. This is indeed strange since the filter material really looks to be in good shape. Last summer I replaced the motor on the pump due to...
