New Resources GroupBlue Streak Pro 200 Dye Tablets (Detect Silent Leaks) Bulk in EZ Pour Container | Toilet Tank Leak Detection | Plumbers Friend

works well with only one tablet in the tank

Best pill so far I have seen that does what it says it will do.My plumber gave me some orange pills that were garbage. You had to crush it and than it will turn the water orange. But the worst part was that pill color wouldn’t go away for 5 plus flushes.But this pill is amazing. One flush and you’re done.If you’re a plumber or management company switch and won’t be sorry.

What I like about this product is it dissolves quickly like an alka seltzer and very easy to use. It is rather expensive though and certainly don't need 200 tablets. A smaller 50 tablet container would cost a lot less and still be enough for years in the typical home since toilets only need to be tested every 6 months or so. I used to use food coloring but it tended to get all over my hands and did not easly wash off. These are much cleaner and easier to use.

horror! do not buy !!! this does not work. just Colors the water for two hours. I took the pill with wet hands. my fingers are stained and I can’t wash them for three days 🤦🏼‍♀️. I will never buy again.

It works very well and doesn't cause any damage to your toilet. Once flushed, it's gone leaving no residues. Once every three months or whenever you think you should check your toilet, one single little tablet is sufficient.
