Test Question

[simer]

Hi

I've bought three different ammonia tests. Crazy, I know. I'm doing a fishless cycle on a new larger tank that I have bought.

Anyway, I tested my older, smaller tank today and I got three different results! The test I have had the longest and the one I have used the most (API liquid) gave me a reading of 0ppm. The other liquid one (TetraTest) gave me 0.25ppm0 while the tablet one I've got (EasyTest) gave me 0.1ppm. Which one do I believe?

It sounds like it's probably fine and the tests have picked up a little something for one reason or another (sometimes additives can interfere with tests) but it's safest to go on assuming that the highest one is right, for 'better safe then sorry' purposes.

Thanks. I think that's a sensible philosophy. I'll keep my eye on the situation.
