Great Thanks for getting those readings...It would be difficult to keep doing water changes to lower your Ammonia levels if you continue to add water with Ammonia in it... right? Just like my water... I have Ammonia at .25 all the time too. That means that I always have to look for numbers ABOVE that. That I need to be using a good water conditioner too , I use Prime now. Costs a tiny bit more but goes a huge long way. Actually works out cheaper I bet. And yes is smells bad.
You will however see each number spike much higher than what you are seeing now. You will definately see your NitIte number rise and fall back to zero before you see a steady NitrAte number. But again... looks like .10 again is a normal... you will be looking to be around .20 at the end.
Water changes will dilute down any of the numbers if they spike. (back to your normal numbers)
(prime is great for spikes in chlorine too when your city dumps extra chlorine to kill bacteria spikes in the water system.... and they don't tell us fish keepers they are doing it!!!! Grrrrrr) You can double the dose without worry. )
As you are new to this, I recommend getting a small calender and write down your readings and changes you make. It's hard to remember what you did, 4 days ago.... no maybe it was last Tuedsay... no.... wed....oh I don't remember... Write it all down so you have a log. Lol
Just be patient and you won't experience the fish deaths that the rest of us have.!!
Do you know what your PH is? and what kind of fish you are thinking of?
