How is it possible?

Hi

How is it possible to have my tank for like 1 year and have the following readings?

0 ammonia
0 nitrite
0 nitrate

shouldnt i have a reading of something?

I have a 600lt tank with 8 discus, fluval 405, i do a 15% w/c twice a week

those readings doesn't mean there is something wrong - it means your filter is doing its job.
Yes you usually have a reading of Nitrate - but if you have a planted tank - with the water changes your doing - that might be the reason for the no nitrate - its not a bad thing - its actually quite good. Just remember if you do have a planted tank - add plant food.

my tank is barebottom tho?

your test kits are out of date

but i even got them tested at the aquarium & i got a new test kit and all gave zero readings to

are you leaving the nitrate test for enough time to devolpe? my nitrate test takes 5 mins before it reads a color change.

yep i have even left it up for 10mins & still zero for all 3

its a good thing that your result shows zero. No need to worry.

but everyone says you should have some reading for nitrate?
