hot tub

We inherited an older pool and hot tub. Both beautiful! When we first moved in the jets in the hot tub had tiny bubbles in them all the time, even when the little air vents were cranked all the way down. I was also losing water in the pool so I had some leak repair work done, the weir edges in...

Hi All, Quick question - Is there a BIG difference in efficiency to get one of the below over the other? I'm in Central California where winter temps get down to 40's and maybe a freeze here and there but no snow. Cover 1 - 30oz Marine Vinyl, 83" x 83" with 5" skirt , 4"-2" taper with 2lb...

Our pool/spa store is closed for the week due to the holiday and I’m out of calcium hardness increaser. I have some HTH Calcium Up for my pool. Can I use that in my hot tub?

We recently got a hot tub and was given the @ease system to use. I was given instructions on shocking with 1oz dichlor and 2oz MPS weekly. Well the @ease system wasn’t keeping up with heavy usage. My tub was turning slightly green in color (still very clear) and my CC was through the roof. So I...

Hi all, I'm starting a new hot tub after we got rid of the old one more than a year ago. I do have basic understanding of water chemistry, but I'd still consider myself a beginner. I'm trying to understand what could I have done wrong to end up with white deposit on our brand new FG pool after...

My Hot Tub GFI keeps tripping. The first thing I want to do is determine whether the problem is: 1) the hot tub or 2) the wiring to the hot tub. I want to do a simple test where I disconnect the wiring at the hot tub. I would go to the main lugs in the hot tub and remove the wires which are...

I am building a new custom hot tub and want to make sure what the builder is telling me is accurate. I greatly appreciate any help and I am willing to donate to the forum for assistance. I live in Colorado and would like to be able to use the hot tub year round at 104 degrees. The average high...

Hi there! We are currently building our pool and they are setting the flagstone for our three spillways. Can you tell me: - What is the ideal overhang amount would be? - Should the spillway be flat/level, angled towards the pool or angled towards the spa/hot tub? Any other advice is...

Hi, I've got a 1000litre vinyl hottub which I've had for 4 years. I currently use a number of pool chemicals and test strips (although I am looking to change this). As well as the standard chemicals, I currently use: Scale control (to reduce hard water) Clarifier MPS spa shock Is my...

Hi, I'm on the board of an HOA for a condo complex in Portland, Oregon. We've got an enclosed spa room that has been nothing but trouble this winter. I could go on and on about a lot of different problems we've been having, but I'm mainly trying to address one particular issue at the moment...

I have a older Jacuzzi hot tub. The problem I have is when the heating gets initiated by pressing the UP arrow to increase the temp on the thermostat, it heats, but then a while later I come back and the hot tub is off and the breaker has tripped. If I turn the breaker back on, the hot tub is...

Hi, I rebuilt a hot tub over the summer, about 130 gallons, perfect for us and our space. I realize I have to be extra careful with the chemistry due to the size. Reading tons of articles here and posts. My question is this, as I'm going to get a drop test kit and get my TA inline...What affect...

I searched the forum and just found 2 threads.. one with a question but no answer and the other to a specific product. My question is more general. Is there any product that is safe (for Chlorine hot tub/filter and humans) and that actually is therapeutic? Thank you

I did a search but didn't see anything specific to this.. I understand the cover clips won't handle much wind. I am thinking of using a strap that can wrap around the entire hot tub. Does anyone have any thoughts or solution for this? Thanks!

Can anyone send me a photo of how you have your wiring for a sub-panel to a spa? My electrician used a breaker from old time spa hookup and it doesnt work. Now I have a breaker/box that will work but I need a photo to show me what lead goes where.

In a final push on sanity we decided to change our mind to place our new hot tube (delivery Saturday) from a (covered) lanai to the edge/near corner of our pool deck. Florida winds and heat are going to... well that's the question... is there some UV spray to use to protect it? What about the...

Hey all, First, thank you for this forum. I've learned a lot! I think I'm also very confused. After having some company for the weekend, I noticed that my FC went to 0. I decided to do a SLAM to bring it back to health. Post SLAM, FC levels (once I started measuring again) went from 12 to 5 in...

For the past year or so, I've done sanitation and shock in my 500 gallon tub with Bromine and MPS mixes. I've recently shifted from MPS to a dichlor-based shock. Since my shocks are typically no more frequent than weekly, should I have any concern of CYA buildup? I don't do any CYA testing...

Hello All, I have recently bought an Intex Greywood inflatable hot tub and have been very thankful for this forum. Here there is consistent information with actual logical science behind the recommendations that is so difficult to find elsewhere. I decided to use Bromine for sanitizer since it...

Hi there! I’m renovating my new home in Palm Springs, CA, which came with an in-ground pool (gunnite) but no spa/hot tub. We’re looking to add an in-ground spa and wanted to keep it separate from the pool for aesthetic reasons (the existing pool is kind of an oblong pill shape and it would look...

Does anyone know how much chlorine is released from a hot tub as chlorine gas? Obviously, there are a number of variables here so we'll assume perfect water chemistry and FC level. Obviously, chlorine gas is 'suboptimal' for inhalation and I've always assumed (maybe incorrectly) that the level...

In January, I bought a house that came with a hot tub (manufactured 2003). The previous owner said it had been sitting empty for a couple of years, but worked fine. Inside looked clean. Filled it up, balanced the water and starting around 3 weeks it was forming a chemical smell and by 6 weeks...

When I use pool math for my spa do I label my spa as fiberglass or vinyl? Or does it even matter? My spa is on its own from my pool so it’s a stand-alone cal spa about 425 gallons.

the past 3 days my hot tub had an error code HH which means high heat. the temp flashed at 111 then when i hit a button it reset and the temp read 95. i first thought this was because dirty filter. i have cleaned the filters the past 3 days best i could in stationary tub because hose and such...

We just bought a used hot spring spa and there are sinking black flecks (seem like tiny rocks). They don’t disintegrate upon touching. Any insight? Happened before we even got in it but was clean when we loaded the water. They treated/flushed it before delivery. Thanks in advance!

I'm a new spa owner following the How do I use Chlorine in my Spa (or pool)? approach to maintenance. I'm also using the Pool Math app to log my upkeep and calculate any chem additions. I recognize the app is mostly for pool use, but is it possible to change a setting somewhere so that the...
