It Actually Worked! Until it didn’t. Six month UPDATE - My Hot Springs spa is 30 years old and I have performed several repairs over the last 7 years that I have owned it. It still works fine and it meets my therapeutic needs. I recently moved 700 miles and loaded it on a trailer. At my new place I set it up it and it had developed a small very slow leak. I tried finding the leak but it was obviously coming from inside the styrofoam insulation. No way could I find it. While searching for a new hot tub and being shocked by the cost of a new one, I came across Marlig Fix A Leak. At first I thought, no way could this work. But the reviews made me want to take a chance Once I received the bottle I followed the instructions removing the filters and poured in the bottle. By the very next day there was no more leak. The instructions say to drain the spa and let it sit for a few days to cure if the air temperature is not going to be too cold. Well it is very cold, below freezing at night here, so I opted to not drain the tank. I did replace the water (330 gallons). It has now been 25 days since I used the Fix A Leak and the patio is still completely dry. I am truly amazed and very happy! This stuff actually works!!! Update: one week after the above review and singing, its praises, the leak returned. I’m going to order another bottle and try it again. Update. So I ordered another bottle. This time I waited for Spring and warmer weather. I followed the directions once again and let the hot tub run on high all day. Then i I drained the tub and let it sit empty for an entire week in the warmer weather. I refilled the hot tub and no more leak. That has been six month that I did the second treatment. I think the key was to let it sit empty for a few days. I use t hot tub almost daily and in six months not a drop leaked out. This stuff really works but do empty the spa after treatment and let it sit for a few days. I am very happy that my now 31 year old hot tub still works great and doesn’t leak! I upgraded my review to five stars!!! Review: Absolutely fantastic product! - Can’t say enough good about this stuff! Had an inline leak somewhere from the skimmer basket to the pump. Followed directions and it stopped it completely. It’s been a year and it’s still holding. Saved me $$$ if I’d have to have had pool guys, plumbers fix it. ## Features - Designed to fix leaks for Pools, Spas, & Hot Tubs in virtually any material - Will permanently seal holes up to 1/8" in diameter - Use 8 oz per 1,000 gallons for minor leaks.

Does it that I received a bad batch?** A: My husband said when he added it (twice) it was just like skim milk in color and consistency. After the 2nd attempt it worked! Good luck! **Q: will this work on an above ground pool with a sand filter?** A: Maybe but you have to bypass the filter. **Q: I have bvc under the round 4' but it leak can marlig fix it** A: Not fully sure what the question is - Essentially this is a liquid sealer that gets into suspension, when pumped around the water of the tub it tends to aggregate anywhere that water is leaking out and form a plug. It then sort of semi sets up and will plug quite a few leaks - if you have access to the fitting then get in there and fix it. But if its a hard spot to access give this stuff a shot. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It Worked! It Actually Worked! Until it didn’t.
