Good day all!
For the past few days I noticed the Ammonia lowering (or rising?) at 0.25ppm. I wasn't testing the other drops before because they were always in 0ppm and PH 7.6.
But now I tested the water and the PH is still 7.6 and the Ammonia looks like is still at 0ppm, but the nitrite and nitrate changed!
The Nitrite is at 0.50ppm and the Nitrate is at 5.0ppm. My last water change was last wednesday or thursday and I did a 50% water change (I keep forgetting making notes on my calendar).
I'm using API Quick Start and API Stress Coat+ and once a week I use API Leaf Zone for my plants.
Could it be because my filter is not cleaning the water enough because of the plastic baffle? I bought a new filter, but I haven't used it yet.
What should I do? Should I do a 50% water change?
Please help me and thanks!
