We disagree, have hundreds of customers using them, including myself for 13 years.

If that were the case wouldn't any home without a filter meaning there's chlorine in their toilets have a seal issue?

I guess, if you want to clean your toilet bowl every day, you can avoid calcium build up, but most people don't want to do that.

Perhaps because your diluting it with water that's already in the bowel.

Empty most of the water fill it with 100% Lime away or CLR it will absolutely remove calcium

But it has soak for several hours.

THis stuff will dissolve a seashell

I have even tried emptying the bowl and soaking the bowl with an entire container of CLR overnight. It didn't work. But, gently rubbing a wet pumice stone on the bowl surface will remove the calcium build up in a few minutes. If you are afraid of scratching the bowl, then don't use it, but it works for me.

I lived in South Florida my whole life and never had this issue. I don't have any kind of water filter softer system. But if the toilet's not flushed every day or two I get that black ring and I don't understand what the hell it is!! I have to remember to go on any other two bathrooms to flush them.

My best guess would be mold, esp if you kept the lid closed. Pour some bleach on it and that should eliminate it if it should be mold.

maybe just maybe it's the black bladder failure, in your expansion tank.. 60.00 bucks common fail

Rich, I agree but since this is cold water line not hot I doubt it.

But they fail all the time we see several a week that need replacing

they only last on average 3-5 years, good idea to check the bladder with a tire gauge they should be about 5-60 psi every 4-6 months

When they fail the water pressure increases in the entire house

toilet., tank was clear. Surprised that would happen with the Nova filter.
Any idea what would cause this, and is our water safe to consume ??

Maybe not flushed completely, leaving some material behind.

Not advised to put chlorine in the tank it corrodes the rubber parts and you will be changing out the parts. You want something that goes in the bowl.

I agree, but apparently there is a product that claims to be safe to add to the tank water.

It is not just the chlorine but the concentration. Thinking water from the tap is 2 ppm and a tablet dissolving in the tank can be 1000 ppm depending how long it sits there.

Yes, the pumice stone is the only thing that works once the ring has formed. I tried vinegar, hydrogen peroxide, and lots of scrubbing but nothing worked until I bought a pumice stone from Amazon. Worked wonders.

I agree. Our builder warned us about this.

We have been recommending the tabs of chlorine for over 13 years, works great.

Over 20,000 homes

No one ever had a problem with the rubber breaking down.

If you're concerned the rubber caskets are about $10 and need replacing 3-5 years or so..
