Leakmaster BLUEDYE8OZ Pool DYE Lekdetectie, Blauw

If you are reading this just buy this stuff! I knew I had a structure leak, but had zero faith this stuff would help me find it so I did the dumb thing and guessed by using epoxy all in my skimmer opening and even grouted a few spots I thought could be the source of the leak once the water level stopped dropping. Everything I did was a waste of time and $. I bought this as a last resort and in no time I found a pin hole leak in the title grout on my top step! Without this I never would have seen the hole or guessed the leak was even in that spot! Use this to check all your spots that have grout.

J'ai enfin trouvé la fuite de ma piscine qui était cachée sous le volet du skimmer grâce à ce produit

As expected. Worked well. I needed it to detect a leak in my pool. Don’t need a lot. Just a little will do the job. If I could I would have bought a smaller bottle

Works very well for intended use

Works well. I saw some reviews saying it disperses too much, but that wasn't my experience at all. In fact I found that you can create a very intact thin 'worm' of dye if you dispense it in a very gentle way, moving the tip of the dispenser slowly back through the water as you go. But you don't actually need to do that - even just a little squirt that spread out a bit was enough to show that water was clearly moving towards one of my pool inlets, strongly indicating the likely source of my leak.
