if you need more help with hot tub care, grab the free Hot Tub Cheat Sheet at www.swimuniversity.com/spasheet Clearing up cloudy water should only take an hour of work (or less), but it's worth running your filter afterwards for an entire day. If you know why your water is cloudy, you can skip ahead to the walkthrough that starts at 03:14 👍

So just to clarify if I'm using bromine tablets with a floater and want to clean it a little extra. I can use chlorine shock and it won't affect me using the bromine tablets? Cuz I know I'm lying at least as far as the tablets it said you can go from bromine to chlorine. But if you're trying to go from chlorine to bromine you would need to drain your spa do a fresh refill. Because right now I've just been using the non-chlorine shock. Also can you explain more on the biofilm? How do you flush your pipes is there a chemical that you can buy that will run through the water into pipes and clean out the biofilm if that's the case?

Yes, chlorine shock is okay! It's switching between sanitizers that's a problem. The shock is formulated differently. There are plumbing purgers, like ours: shop.swimuniversity.com/products/hot-tub-detox

what is a hose filter and where can you get it. We just refilled our spa and it is now cloudy

Thanks for the tips. Swim University to the rescue as always.

Any time!

I filled my hot tub about 2 months ago and have only been in it 3 times since. The water was crystal clear but turned cloudy when I checked it the other day, after not being in it for weeks. Chemical levels look fine, and filter is new. Any ideas?

Really struggling to get the water balanced in our new swim spa (containing 1985 gallons) which arrived on Feb 20th. We followed the instructions our spa supplier gave us about using a hose end pre-filter to fill the spa, and we tested the water once it was filled. Apparently our local water utility filters out almost all the calcium (17ppm), but the alkalinity is well over 8.4. (We're in a limestone region.) Again, following the written & verbal instructions we were given, we worked on the calcium balance first... We spent several days adding 7.5 oz of Leslie's brand granules at a time, with 99F water and the pumps & jets running, and kept on testing it after about 15 -30 mins. More than 6 lbs later and all we had to show for our efforts was calcium deposited thickly on every surface but almost no change to the test strips or the in store water test results. Following more & different advice from the supplier's technician.. We cleaned off as much of the calcium as possible while emptying 3/4 of the water out. We also cleaned the filters, and refilled the spa using the pre filter again. Since then, a little calcium has deposited here and there on some surfaces, but it's a fraction of what it was. It still barely registers on our two different brands of test strips. The tech said to balance the alkalinity not the calcium this time ... But we're finding adjusting that just as problematic. We've been adding about 4 oz of Leslie's brand 'dry acid' granules at a time, mixed with plenty of warm spa water and poured into the spa with the pumps and jets running full blast for 15 mins to mix it all in. We've added more than 6 lbs of dry acid over the last week or so and managed to get it down to about 8.0 at one point but it wouldn't come down any lower (testing it about 15 mins after adding each 4 oz). What the hell are we supposed to do? Is it the product at fault or operator error? Oh, and the water is a bit cloudy now, as well. We're running the pumps for six hours every day: Two hours at 8.00am, 12.00pm (midday), and 3.00pm. I'll clean the filters again tonight and then try to leave it running for as long as possible over the next 24 hours. To hell with the electricity bill! BTW - The link on the website to download the 'cheat sheet' doesn't seem to do anything. I tried two different browsers on my laptop.

[@SwimUniversity]

When you say alkalinity, do you mean pH? First, stop running your jets. Hot tub jets aerate the water and release carbon dioxide and raise your pH. And what kind of chlorine or sanitizer are you using? Chlorine tablets can raise pH. Also try this link for the cheatsheet! www.swimuniversity.com/spasheet
