Edit: Actually looking at it, it does seem to read 0.25!!! Strange as on my test kit the 0.25 is a lilac colour not blue! My 0.25 is the next colour up that you have 0.50! Must have changed the kits.
Looks like you will need to top up to 5ppm of ammonia tomorrow morning all being well.
The nitrite reading you got yesterday could have been false (happens sometimes), but as the ammonia is processing you should start to see it rise over the next couple of days.
Once ammonia gets to 0 then just remember to top it up to 5ppm.
Looking Good
Have you used the bactinetes you bought or not?
The API is very accurate providing you follow the instructions to the letter. The only problems some people find is with the nitrAtes test kit as it is very specific in the instructions and the slightest deviation from them can lead to a false result.
I know she wants fishes now, just a little more patience please Mrs Efren, you want healthy happy fish, you dont want to come down every morning to floating, half eaten, rotting fishes now do you?![]()
