Does anybody know why you have to put Ammonia test strips in test tubes? Is there any way I can substitute? I need to test my water NOW and I just dont have those things just lieing around.
 
Ill look into that but the ones Im using are Mardel Master Test strips. they're the kind that have three little pads on a little plastic strip.
 
If you need to test the water NOW and can't, I'm guessing that you suspect a buildup of ammonia in the tank. If that's the case, I'd do a large water change. This should help, and can't hurt (unless the tank has been left without a water change for a very long time, in which case a large change could shock them - then it's best to do small daily water changes).
If you're cycling or the tank is experiencing a 'mini cycle' (spike), a large water change should take care of things until you can get a test kit or some strips.
 
you can't really substitute unless you find out how much water your test strip tube held, measure that amount, and create a similiar shaped hole in something by, i dunno, say drilling into a plastic block or something. in other words, re-inventing a test tube. the amount of chemicals on those two white pads above the pad you read are enough to saturate only that amount of water and provide an accurate reading.
 
These strip tests can be compared to liquid test kits. The little pads hold a special liquid that reacts with the other chemical in the other pad and eventuly colouring the pad at the end of the tab. Id say get a new liquid test kit as these are better for this. Try going on line for the information you need.
 
wrong question?

I think we may be misunderstanding the question... do you mean that you have test strip but are missing a tube to fill with water to insert the test strip? I think that this is just so you don't stick the test strip into the fish tank! Nasty chemicals on those strips, they do not go into the tank. But, any thing should be fine to substitute for the test vial. A small paper cup, not one that anyone will be drinking out of later, mark it "FISH TEST" and put it away.
 
Most of the ammonia test strip I've used come with a small test tube - similar to those that come with liquid tests - into which you repeatedly dip the pad into the small sample of water for a period of 30 seconds or so.

I think Kasakata is right, that the pad releases a chemical as you dip and re-dip it into the sample. Just as with liquid tests, the sample needs to be a specific volume or the test won't read accurate.

I don't know of a short-term solution, although if you suspect ammonia then water changes are the thing to do.

Many companies would send you a replacement vial if you call or write, I would guess.
