No, I don't own stock. I just don't feel like $13 is that big of deal. It sounds like you get 1 applications worth in a bottle of Nix. I gurantee you that 1 can of 'the other stuff that costs $20', will give you more than 10 applications worth.
You said, 'Dilute half the bottle in two or three gallons of luke-warm water, and toss in your BP. Let him swim. Keep him in there for 10, 15 mins. or so. Use the other half of the bottle and dilute it in an atomizer (spray bottle) and use that solution to soak down every inch of his environment. Clean it down, and throw your BP back in. You may have to do this twice, I never have. Once has always been enough for me. This product will work, and you have no real threat of killing your BP with the treatment. With the money you save, you can buy me a 'Thank You' card. Good luck.'
So, you take your snake out and let him swim for 15 minutes, I take mine out to feed and spray the stuff in. Less than 10 minutes later he is back in and I am done. You'll still be watching him swim around (or holding him in the water is more like it). Then, you still have to clean his tank. Gettin the idea yet? Then you say you may have to do this twice, perhaps not. Well, now you are up to $14. Okay, so my time is worth more than yours, time is definitely worth more than $6. Big deal. You must own stock in Nix....and like wasting your time, all in the name of a few bucks.
Cheers,
