Hi all

I've posted a few threads about constant ammonia reading of 0.25ppm. My tank is 4 months old and I see Nitrate readings, so I obviously have the bacteria in place for the cycle.

However, I've become somewhat obsessed with eradicating all traces of ammonia and seem stuck at a reading somewhere between 0 and 0.25ppm.

Today I tested my tapwater and tank water at same time. The results are shown in the pictures below. The left is the tank water, the right is the tap water. To me, they both look identical. However, I am starting to doubt my perception of the colour as it looks different in different light and from different directions. I've posted 6 different pictures of the same two test results, held against daylight in different rooms of the house. I think they look either green or yellow depending on the ambient lighting in the room. Thus leaving me confused about whether I have ammonia in the tank or not or whether I can actually tell teh difference between green and yellow.

If its green and the the tap water has ammonia in it, then why is this ammonia not being eaten by the bacteria in the tank that are turning the rest of the stuff into the Nitrates and what would be the point of doing water changes?

what do you think ?

This is why I wish there was a machine to record everything with accurate results. Well there are those things you stick to the tank wall, but how much do they cost... and are they accurate?

Looks yellow to me from the pictures in the light.
 
I can see a definite green tinge in the left tube!

Also I find putting the tubes side by side against a piece of white toilet paper gives the clearest result.
 
well seems to be more yellow votes than green votes. Which is what I'd expect after 4 months. But Still think I see a slight green like Jimbo. Mystery is why?
 
I'd say the tap water has slight ammonia whilst tank water is showing zero.

With regards to why do water changes - isn't that why a lot of dechlorinators (such as Prime) bind ammonia into a safer compound that is still 'food' for the bacteria to process but is harmless to fish?

My tap water gave similar results today but a test 6 hours later from the tank showed a zero rating so all is good
 
I've been using Prime in the new water each change. But also been dosing the tank mid-week with a detoxifying extra dose. Think I might start skipping the mid-week dose if the consensus is that my results are yellow.
 
Yes I highly recommend Seachem Prime as a dechlorinator/detoxifier! What are your tank stats/stock dazbud?
 
@ Jimbo :

Nitrite 0%
Nitrate up to 20ppm before weekly water change
Temp : 25.5C
PH about 7.6

2 x dwarf gourami
8 x neon tetra
2 x baloon molly
2 x platy
