Frequently asked questions about our Metal Prevent
Q: What if I'm still getting scum stains around my waterline?
A: Metal prevent is specifically formulated to prevent metal stains, but other particles are still able to create stains around the waterline. Unfortunately, depending on your environment, metal may be just one of the stain control formulas needed. Limescale and calcium buildup is another common spa issue that requires stain & scale control formula.

A: Our spa metal prevent formula is proudly made, packaged, and shipped from the USA.

Good to have around
My first hot tub, so I bought the complete kit. I really didn’t need all the items here, but it is good to have just in case. A little bit on the expensive side, but it does come with everything you need. All in all the product is fantastic. I use the shock all the time.
Works great!Fast results.With this quality and the price, this is really worth it to get.I would recommend this chemicalVery satisfied with the result.
All the chemicals I've needed in one box
This is a simple way to get my inflatable spa ready for use. Aquadoc's starter kit had all the chemicals I needed to keep the water ready for relaxing. The only "extra" would be the metal prevent, but I use is 4-oz each water change to add a bit of protection the pump. Of course, the bottle only has large volume information, but 2.5-oz for each 100 gallons is their recommendation.I'm concerned about how long the floater will last, but it's working out so far. In the past, I struggled to maintain the proper bromine balance using the built-in dosing ring, but this new approach has proven to be more effective. My box did arrive with the Bromine tablet bottle top not ******* on so there was a fair amount of Bromine dust coating each bottle.
