Some fake plants/ some plants.
Story: A few weeks ago I lost my last fish. The tank was empty for about 2 weeks. I tested using API kit. Saw I had an Ammonia spike to .80ppm. Did a 50 % water change. Dosed with Prime & Stability. Next day the Ammonia dropped. Did the water change and dosed again. Did this for a week-7 days. Ph stayed steady at 6.0 the whole time. Ammonia dropped to 0.25. No Nitrite change ever, stayed at 0 the whole time! But the Nitrates rose to 0.25ppm. I added a few plants and dosed Aquarium Co-op all in one and added fertilizer tabs into the gravel. Next day the Ammonia stayed and the Nitrates rose to 0.40.
I did one more 50% water change. This was Monday of this week. I tried doing an ammonia calculator app that measures NH3 & NH4. It told me I had 0.00001 NH3. Said I was okay for ammonia. So I stopped doing the water changes thinking that the API kit was reading it slightly off since they say it combines the NH3 and NH4 to get its reading.
Yesterday I added Seachem Neutral Regulator to try to get my PH up. I had also added two aerator balls to get more agitation. Read somewhere this would help raise the PH.
Today I tested again. PH is still 6.0. Ammonia is at 0.5ppm now! Nitrites 0 still. Nitrates 0.40ppm.
I’m at a complete loss of what to do next. Water changes for sure. But what else?
