My Jacuzzi tub is spitting out black specs when I turn on the jets. I've done everything I can think of bleach,etc. Help

Don't use bleach! I learned the hard way, as it corroded my rubber seals in my whirlpool tub. After that costly repair, I found a product called Plumb Clean on the kitchenbathsinks.com website. It has worked for me and got rid of the yucky black flakes. I was told that the water settles in the plumb lines of the whirlpool tub and grows mold and bacteria and that's what you see sometimes when you run your tub. Gross! I haven't seen any of that since I started using Plumb Clean over a year ago.

I learned this while living in Japan. Always take a shower first to get clean. The tub is for making you feel relaxed while reading, listening to music or soaking your joints if you have that problem. There is a sponge thing you can buy that floats on the water and grabs hold of any grungy stuff.

Have your hot water tank cleaned and inspected.

When I had a tub I use to use Tang Drink Mix (read about it somewhere). It worked well was cheap and the odor wasn't bad! Fill the tub add tang run the jets and then drain and rinse with clear water (and run through the jets). Cleaned it great and as my kids used the tub too I wasn't worried that their delicate skin was absorbing harmful chemicals!

I have little black beads in my jacuzzi and I don’t have the jets on. When you rub the beads that are like black grease. What could that be?

Same here...Black hard chunks and black oil/grease consistency when rubbed. Hot tub is all of a sudden loud and sounds almost grinding? What could this be?

Any updates here? Bought a used hot tub and black tiny rocks or particles sink. Please help

I had this problem with the hot water in my bathtub. It was the cartridge in the hot water handle that had deteriorated. Replaced it with a new one bought on Amazon and problem was fixed.

It is biofilm. A combination of mold, mildew, skin flakes etc. You need to clean your whirlpool tub. Just Google it because there’s a lot of different ways and chemicals you can use. Vinegar being the most popular one.

When I bought my tub I was told to fill it with cold water and pop in two Milton sterilising tablets once a week to keep it clean. Certainly seems to work.

First, drain the water from the tub, then add a cleaning agent, turn the jets on and allow them to run for 15 minutes. Drain the water below the jets, wipe down the tub, and repeat if necessary. If black flakes persist, remove jets from the tub to clean out mold.

Mold may be building up in the jets. Try spraying them with vinegar and if that doesn't work, they may have to be removed for deep cleaning.
