Green Gobbler Red Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

Not sure what the other reviews are talking about, this product is easy to view in daylight and looks pretty cool. Works great, will update later on the removal process. My pool is about 10k gallons and I used two red solo cups worth of product instead of the entire gallon to track water flow and check for leaks.

This dye is fluorescent so it works best at night with a black light flashlight as it glows in the dark. Not harmful to pump or circulation. It soon dissipates after time.

When they say “red water tracing,” they mean RED. This isn’t a subtle little pink tint—this is full-on crime scene levels of red. The first time I used it, I thought I had accidentally summoned a horror movie in my sink. But hey, at least I knew exactly where the leak was!

NOT FOR INGROUND POOLS! We read the directions, added the product as directed and then watched as our entire pool turned purple. No way to find a leak. I think you would have to have a large tear that was sucking water hard for this stuff to work. It’s been 6 days now, the pool water is still a dark pink color, and even though it is a pretty color, it is not how you want your pool water to look. We’ve back-washed and rinsed, shocked and used clarifier. Some product did get on the cement pool skirt and it did wash off, so for one star I’ll give them the part where they say it is non-staining.

worked as described. Did not show up well in grass

Was very hard to see during the daytime unless you were close. Green is much better for that. But, it works well in the dark if you have a black light UV flashlight.

I wasn't sure how much I would need...Definitely not this size. A 5ml syringe was used to find 4 holes in pool liner on 18ft round pool. Only needed 2ml. Worked great to find holes & easy to see it sucked up or not. I got red. Only need small acts to put where there may be a hole, so doesn't change water color or stain pool.

Good stuff!
