I'm putting a 240V hot tub on an existing concrete slab about 5 ft from my garage. Can you run electrical run in conduit on top of the concrete OR is this not typically allowed for code? If not, any other ideas so I don't need to rip up a good concrete slab? Thanks, Doug

I meant to say like $100-$120 per 4 month period but I'm glad to see Amazon carries it.

I just learned about Frog @ease inline system and floating system. It looks more expensive (like $100-$120) per month but I'm curious what folks think about the safety of this system and any other thoughts.

If I switch to the Chlorine / Bleech plan posted as a sticky on this site, would you recommend keeping the nature2 also OR add Ozone or both? When you add the chlorine / bleach after use, should you leave the cover off for a while or is the amount low enough that leaving the cover off is NOT necessary. Which model or ozone do you recommend? Thanks, Doug

I have a Marquis spa that's 15 years old. It has ozone but I've heard there is no way it is still working after 15 years.

I have been using Nature2 low chlorine recipe in my hot tub. I was just reading about the Spa Frog system and seems much easier with low levels of Bromine. Any thoughts of spa frog benefits or drawbacks compared to Nature2. Do you recommend using spa frog just as directions say OR do you make modifications to directions. Thanks, Doug

What I'm referring to is Potassium peroxymonosulfate https://www.spadepot.com/Oxy-Spa-Non-chlorine-MPS-Shock-One-Half-lbs-P77

1. What do you think is the easiest and safest manner to run a hot tub with the lowest amount of potentially harmful chemicals (choline, bromine, etc.)? 2. I have a 400 g. hot tub. It is usually used one to two times per day by 1-2 people for 10-20 minutes at higher temps (like 103) and occasionally 2-3 people will watch a show or movie (60-90 minutes) from the tub at lower temps like 98 degrees. I currently use Nature2 stick low chlorine recipe and use MPS as indicated I'm the directions and use diclor shock as they recommend if MPS levels can't be kept high enough Or if water is

If MPS is low with Nature2 before getting in, Nature2 recommends adding MPS before getting in. How long do you need to wait to use the tub after adding MPS? Thanks

I have been using AquaChek MPS 3-in1 test strips AND AquaChek Yellow - Chlorine 4-in-1 Test Strips to measure PH and Alkalinity. The AquaChek MPS 3-in1 test strips show substantially lower PH and Alk than the AquaChek Yellow - Chlorine 4-in-1. What test do you like for Ph and Alk? Do you find the AquaChek MPS 3-in1 test strips OR AquaChek Yellow - Chlorine 4-in-1 to be more accurate for Ph. and Alk? Thank you!

I add MPS after every hot tub use and shut the cover right away? Is this likely to damage the cover versus shutting the cover later. I live in MN and can't imaging going back outside to shut the cover 15-30 minutes after using the hot tub in the winter. Thanks, Doug

I have a vulcanized rubber mat in the bottom of my hot tub that makes the bottom non-slip that was installed by the previous owner. Will this leech chemicals into the hot tub that are bad for the hot tub or the people that use the hot tub. I would like to leave it in there but I don't want to cause problems for the people or the hot tub. Thanks, Doug

Thanks for the clarification. What sanitizer do you recommend after bathers? Does Dichlor work well. If so, do you just recommend the typical amount specified on the bottle?

I have a long (12" or so) crack in a manifold in my hot tub. Will Flex Seal or some other glue or product fix this? Or, does it just need to be replaced. --Doug

With the Nature2, they recommend testing MPS before getting in, using MPS after each use, and using a Dichor when there are clear problems. (see attached directions). I've read a lot of articles that promote the use of Nature2 following this procedure OR keeping 0.5 Chlorine. Is there research or science to support the use of Nature2 in this way? Are folks having success with Nature2 and staying safe/healthy? Thanks, Doug Nature2 manual directions.pdf
