Weekly water test showing ammonia in my planted 10g, 1.0 I do 20% wc, retest, same results. Do another 20%, retest, same results. Nitrites .0 Nitrates .05
pH 7.4
I wait til today, test water and again it's showing 1.0 I change media will wait for a while and test again.
I tested other tank using the same kit and all showing .0 ammonia.
What could be causing the ammonia spike in this tank? Specially after the water change, I don't get it.
The fish however are active, feeding well and best of all my mama endler has had her babies!!!
