Hi, For anyone that has used Jack's magic copper stain remover powder (sulfamic acid). Did your water get really cloudy? How long for? Any idea why this is and can I use a floculant or a clarifier to get rid of it? Thanks!

Hi, So I am currently using Jacks Magic #2 stain remover (sulfamic acid) to remove stains from a Pebblecrete (I am from Australia, not sure if it goes under a different name in the States) pool. And I am using "the Blue stuff" (HEDP) sequestering agent. I have a couple of questions. Does...

Thanks for link! Will get one of those kits

Thanks for the insight! If your outdoor pool is doing that, then than I can't imagine how my pool will go, it literally gets zero light for the vast majority of the time. I will probably have the thing turned off most of the time. Maybe I need to look into one with more advanced scheduling (have...

Hi, Our pool has been sitting for a year without sanitiser (long story) but remarkably it is crystal clear probably because it get no UV light and is indoors. Anyway I want to start up the pool now properly for the first time. Once I get the pool working we will have very irregular use, there...

By bypass system you mean one which directs a certain percentage of the pumped water from the pump through a UV chamber rather than all? So I am assuming contact time is quite important right? Like does it work on an all or nothing principle in the way that if the sample of water hasn't seen UV...

Hi, and thank you! :) There are a few skylights but the pool is covered with a motorised pool cover that is completely opaque unless the pool is being used. This is a residential pool and I would say it is maybe used for an hour a day by a maximum of three people. But thank you for the...

Fair enough! Will definitely run the pool for a bit with just chlorine and see how it goes and perhaps use MPS to handle the chloramines if they become a problem. If we do decided to go with UV: Our interest isn't really in reducing the amount of chlorine we use, just to keep chloramines in...

The bather load would be between 1-3 people per day for approximately an hour. Is the reason you would recommend the uv system over the ozone system because of safety, or do you think the uv system is a better system than ozone? Thanks!

Hi, So I know that it is recommended to have a 5-10ppm CYA level (or 20-30ppm for the ease of measurement) in an indoor pool for its ability to buffer chlorine. I also know you have to have a higher CYA level for a SWG system (close to 100ppm) than you would have for a liquid chlorine regiment...

Hi, I have a 12,000 gallon indoor pool which I am converting from an ioniser to a chlorine system. I have done a lot of reading on this forum and picked up some very useful information especially about the addition of CYA to the water as a chlorine buffer. One of the things that was...
