Helped ID my stain
I used this product because we just had our pool refinished with Florida Gem Aggregate and it started looking green. I thought it was algae so I bumped the chlorine up and shocked it a few times. The stain pictured didn't clear. Thought it was mustard algae so tried phosphate remover and that didn't work. Finally I dropped stain solution #2 for copper and scale and it cleared that spot up for me. The white stuff in the Anode was new and do I think it is some form of scale that has caused the stain. Now I can target it without wasting money on unnecessary chemicals. Results may vary but it worked for me.

Jack’s Magic stain ID kit. Easy directions
Product did not confirm the cause of the staining on my new Pebble Sheen surface. Packaging was fine.

Didn’t work for me
Perhaps this works for some folks, but not for me. Difficult to apply to pool wall stains, requires a mesh bag or a woman’s nylon. Did not remove or identify my staining problem.

Waste of time and money.
Worthless. Lots of steps. None of them made any difference. Waste of time and money.

Works... for METAL stains?
I did not have much luck using this to diagnose an organic stain.BUT, then again... I should have done that WITHOUT the kit.I do like the kit, would recommend for testing for metal stains, very useful.FIRST, test for organic with normal (cheap) chlorine tablet.My take

Pool stain removal
This was trash and the instruction on how to use it was terrible. You have to use a nylon or some kind of fabric strainer and place it directly on the stain. Some of my algae or other chemical stains are in deeper areas and I can’t image leaving it in place for any long period of time for it tell me what kind of stain it is.This was useless for me and I couldn’t even return it unused.

Helped determine what was on my pool liner.
Had a scale-like build up on my liner floor. Local pool store said it was "probably" algea. Spent $ on treatment. Ordered this kit and discovered it was actually iron scale from my well water which can be dissolved and removed my axolic acid powder in a cpl days. I mail ordered a 5lb bag of the powder from a company in Florida.. but many pool stores sell it but charge more for a lower concentration. Anyway.. jacks magic was the answer to discovering the problem.

Great tester kit for spot identification in pools!
Etching on the bottom of the pool. You use this kit to determine which product you need to treat further. As soon as we laid the (purple) pouch on top of the etching it disappeared.
