SpaGuardSpa Complete (70 oz)

Our hot tub is ~ 300 gal & I put 2 tablespoons of this product into it weekly. It keeps water softer and gentler - not as much chemical feel from our bromine tablets (I put in 2 per week of those). It's a good system between Spa Complete, Bromine tabs, & occasionally I shock the water with a bit of the Enhanced Shock by SpaGuard

I read the other reviews about people having problems with foam. After checking all of my other chemical levels and getting them all balanced, I mixed in 25 percent of the recommended amount of this product, and let it mix for about 20 minutes, then let it sit, then another 20 minutes or so of mixing with the Jets - foam was pouring out from beneath the lid of the hot tub! Now I have extremely cloudy water, permanent foam no matter how much I scoop out, and a yellow ring of scum all around the top edge of the water. And I don't even smell it at all. Ugh... My hot tub is barely one month old. I guess I'll learn how to drain it tomorrow morning.Update (months later):I decided to try this again with a brand new filled up (and scrubbed clean) hot tub. I got my chemicals all in correct balance, then turned off the Jets. Put in this product. Let it sit with no jets for 24 hours. Just as previously, once you turn on the Jets, you get an overflow of foam. Literally foaming out of the top of the hot tub. I decided to get in anyway since this was brand new water. After a brand new cleaning of the hot tub. Everything was slimy and extremely slippery. There were yellow and brown webs of crap all over the walls of my hot tub. It's not even a year old hot tub, and I get these resultsI am just going to find a place that will recycle this or dispose of it properly. I wouldn't recommend this product to anyone at all. Ever.

I used it while adding other chemicals on my weekly maintenance. I like the smell but I think it interacted with the other chemicals and caused a greenish ring around the top. It was sticky and got all over my skin since I got in during the night and couldn't see very well.

We've been using Spa Complete for a couple years now. We have a small hot tub that gets used daily and the chemicals tend build up pretty quickly, which creates chemical odor issues. Spa Complete does a great job of eliminating the chemical odors and makes the water feel "softer" if that makes sense.Several people mentioned bubbles. A few bubbles is normal, but if you see a lot of bubbles, then you are adding too much. A little bit goes a long way. It should not look like a bubble bath. Make sure you shake it up every now and then, or when you get to the bottom of the container, what's left won't be as effective.Yes it's expensive, but should last several months. Again, you don't need to add a lot.They do seem to have issues with the product being damaged in shipping, but that's the fault of the delivery companies mishandling the container. If it arrives damaged, request a refund.

Been using this for years for our hot tub

Just over priced, I’ve got it as back up if the water needs help. Is good, smells good, you won’t be sorry…

So, this product is really amazing… if you don’t use too much!! Comes with a measuring cup/lid covering the sealing cap and directions say capful. I assumed the measuring lid and things got a bit murky. I let it correct itself, tried using the sealing cap for measure and things have been great since! Real helps to cut down use on other chems.
