It’s gotten worse throughout the day and is a darker yellow now. This has to be iron right? It couldn’t be something else? My fill water was tested for iron and it was 0.1ppm. What gives?

Right now I have a sump pump in the tub and filtering water back through my pre screen filter for iron. I'm hoping this will do the same thing as the polyfill method? Here is the filter I have - Amazon.com : Hot Spring Spas Freshstart Clean Screen Water Pre-Filter 76028 : Garden & Outdoor...

Sorry, the .1ppm is from my fill water, which is going from the well, to the iron curtain filter, to the water softener, to a pre screen iron filter. So was surprised I still had any. But should have known as my levels were high to start. But any ideas as to why my water is still yellow after...

Hi everyone, If you remember, I had the issue with super high iron in my fill water. Water turned dark yellow when I put the chlorine in. I drained it, scrubbed every part of the tub, filled again from the well, through an iron curtain filter for my house and then through a pre filter screen...

Thanks for the help AO - I appreciate it! Ran some water tests from my TF-100 today. Here are the numbers: CC - 0 - 0.5 TA - 140 PH - 8 (maybe higher?) it was pink Calcium - 1250 (!!!) Thinking I probably need to drain again now as Calcium is so high. I filled with the Portable On the Go...

Hopefully some people are still following this since it was moved. Any suggestions for a iron reagent test? I’m having trouble finding one that isn’t test strips.

I appreciate seeing all sides here, so thank you all. Hope to not cause a stir, just trying to figure out how to enjoy the hot tub :) The minerals I put in the skimmer basket are in a case and what was recommended by the hot tub store. They said to put a new pack in each fill. I did use iron...

Well that was quick. The iron out cleared it all up and it’s crystal clear now. But next time I add chlorine will it turn again? Or does that iron out truly take it out? I thought I read here that there’s no way to take iron out with a chemical

i just added just under a 1/2 cup of iron out. If that works do I need to do that often or just on a fill? As for iron still in the fill water, maybe, but I put an iron test strip (made just for iron test)in the tub yesterday once it was half filled. It showed no iron at all....

Update here. I drained the tub through a sump pump and then got the bottom part out with towels so all I could see in the tub was dry. Iron “stains” throughout acrylic shell, so I wiped the entire shell with microfiber towels and around each jet. Completlely clean. I then filled up like this...

Very close A.O.! It would have been a perfect solution if we still had the pool. Joyfulnoise - would I be ruining my whole house softener if I’m taking water after it? The iron from my well water (and all water from well) goes into the Iron Curtain filter, then in to the water softener. I could...

Thanks! Is this any different than using my whole house water softener?

Ok I think I found them: https://www.portablewatersoftener.com/shop/water-softeners?gclid=Cj0KCQiAst2BBhDJARIsAGo2ldWc_hrFknyJy20QyUcr6tJGnrWt3SfKZ8zWEmHcwMgecGl7AgL7MmgaAquREALw_wcB Would this be any different than filling from my water softener for the house?

Ok good advice thank you! I will be testing this weekend once I have the test kit for iron. As for the portable RV filter. Could you point me to what that is? A link or a name of what to look for?

Joyfulnoise - the iron curtain is new as of about a month ago. I don't have iron numbers on the raw water, but have an iron test kit coming on Saturday where I can test. I am 100% sure I have the water running to the outdoor faucet post iron filter, pre water softener. I had them set this up...

Right but when I add due to evaporation - this will bring iron back in if filling from the hose. Any thoughts on what I should do there? I don't want to have to do the polyfill each time.

Ok makes sense. So say I get things squared away once tub is filled. Do I then need to worry about filling from the hose weekly / monthly as water levels go down? That has me concerned as well.

That link is super helpful, thank you! I will keep trying things. Another question - I have the iron curtain filter for my house and this runs to the outdoor faucet, which I ran my fill water through. This was the first time I ran it through after the iron filter was installed. Do I need to...

The hot tub place ran a water test for metals and that was what the reading was for iron after fill and adding chlorine. I could try the polyfill option. Have you ever seen these? What do you think? https://www.hydropuretechnologies.com/shop/metaltrap-filters-available-3-sizes/

Thanks will do. But any recommendation on how to fill better next time? How do I prevent it from happening again? Basically, from what I'm reading, unless I can totally get the iron out (which will be tough as I have 1.7ppm in it right now), how do I sequester it properly?

Thanks! I don't mind draining and refilling this time. I just don't want to do it a ton of times to try and find a solution for how I should fill each time. Do you have any recommendations for how I should fill? What can I do to prevent this or at least handle the high iron? And is it safe to...

Hello - new to hot tubs here but previously had a pool. I filled the brand new tub yesterday and the water was clear at first then turned to a green tint and then yellow tint, pretty strong. I added Metal Gon when first filling and then no chemicals until 20 hours later. Filter was slightly...

I like the gravel idea with 4x4's supporting. I might give that a shot if we pursue it this winter. Also sounds like hot tubs may be sold out in our area for awhile... I don't have power there yet, but plan to have an electrician run 220.

Hello, We recently purchased a new home and are moving in the first week of December. I'll need to update my signature, as we're moving away from our current pool. At the new house we are looking to purchase a hot tub but have a few questions and need some advice. This thread won't be for...

Good advice! I was hoping for a simple answer, but you're right! Thanks.

Thanks everyone. I bumped up the chlorine but looks like i need to a bit more, to double. Just added enough to do that. I'm running the vacuum tonight and then will check chlorine tonight and first thing tomorrow. Any ideas of why I got the algae in the first place though as things were...

Hi everyone, The pool has been running fantastic all summer with clear sparkling water and testing levels staying in check. Came out to the pool today and noticed some algae build up in the corners and side angled walls. I brushed it all up, backwashes and added 1/2 gallon of liquid bleach. I...

Thanks @Richard320 - that makes me feel better. I've done bleach many times and have been careful with it, in clothes I don't care about. So will do the same with Muriatic acid and hold my breath. Any tips on where and how to store it? I think I misunderstand CSI, so next time I'll run the CH...
