    Moving but house not sold. Drain swim spa?

    Mid Florida...Vero Beach. Never freezes. Problem is I am leaving town...house empty. Cl always stable, but pH will be off at times. I can check on spa once a month, but not more that that. Drain or leave it? What do you think?

    Is weekly shock needed?

    As per the spa sticky thread: "Never let FC drop to Zero for any length of time. Keep it between 3-6 ppm normally, min of 1 ppm, and shock to 12 ppm once a week." If my CC is 0.5 or less, do I need to shock once a week? thanks!

    Iron and sequestrants in spa

    Update: I chose to upgrage well water softener system so I have constant supply and i will fill spa with softened water. This will elimiate tannins and visual iron issues. I also found a link somewhere in TFP for Duda Energy web site for very cheap borax (instead of Spa Gentle borax) and it is...

    New spa- Why bother with Dichlor? Why not CYA and bleach

    Quick update summary: 1) Easy to disable ozone. Just pulled power cable off master circuit board and plugged venturi port on injector. 2) EcoPure filter easy to disable- I just cracked open the plastic inner case and pulled out the EcoPure filter insert. Trivial issue as i will disguard this...

    New spa- Why bother with Dichlor? Why not CYA and bleach

    I got my swim spa working. I pulled the power off of the ozone and plugged the venturi intake. Easy to control FC now with bleach. Going to add Saltron Mini soon as well. Ozone = too many uncontrollable varaibles (..in my personal calculation). I see FC on test results, I know bugs will be...

    Iron and sequestrants in spa

    OK...update....spa filled with high iron and high tannin well water. I SLAMed it (...kinda over did it...FC>20). About 48-72 hours later with cover off, the water went from brown/tea colored/cloudy to now crystal clear. Only issue is iron colored ring around edge of spa (easily reomved with...

    Iron and sequestrants in spa

    The latest in my new Spa drama...My well water treatment guy tested our water and yup, has lot of iron. Our softener/peroxide system does a good job cleaning up the water for house use. He suggests we upgrade our water system for two tanks (so one fills while the other recharges), and that...

    Iron and sequestrants in spa

    So I filled the new spa today from my well water and I have that nice clear yellow iron color. I am going to have my water guy install a Penteck DGD-2501 dual gradient filter in a big blue housing so I can use this set up for my every 3 month water changes. In the mean time, any harm in using...

    New spa- Why bother with Dichlor? Why not CYA and bleach

    Still waiting to get my new Master Spa swim spa's power wired up. However, I am going to disable the ozone/UV system before I start up the tub. I know how to just pull the ozone unit power off the main control board. I got that. My question is about the venturi port that would inject (or...

    Any Salt and acrylic tub issues?

    So I asked Master Spa about using a SWG and of course adding salt to the spa for this. Their response was, "We don’t recommend the use of salt systems in the tubs as it converts the salt to a form of chlorine that is not recommended by the manufacturer of the acrylic as it can have a negative...

    New spa- Why bother with Dichlor? Why not CYA and bleach

    Jesyfert3- you are my kind of pool guy. I just put my Amazon order in for the Saltron Mini. I am just worried that the ozone generator is going to mess up my FC every day. I guess the SWG will compensate for that. It seems the UV light not a big problem, but Ozone may be. I plan to do what...

    New spa- Why bother with Dichlor? Why not CYA and bleach

    So my new Master Spa has two filters. One has the EcoPure insert. I do not want to use this. Can I just remove the EcoPure insert and still use the filter, or do I have to buy a new filter that does not have the EcoPure insert? Thanks

    White Flakes of?

    Yes. Thanks for the response. The flakes quickly dissolved with rapid drop in PH and the TA 30-40 range. I will start adding less bicarb each time TA is low ( I used to add 10 lb slugs when it dropped below 80 or 90). And I will let the TA get to 40 or 50 before adding bicarb. Thanks for your...

    Mustard Algae questions

    I think I have calcium scale. I checked some local pool cleaners and they led me down this path. See new pics. I am not sure if I will do anything about it, but I am pretty sure it is not algae. I have always let my TA stay around 40-50 with the SWG...but looking at the CSI calculations, it...
