I'm starting up a planted 12g tank with ADA amazonia. I've got a couple of plants in there, and a filter (it's my betta's future home, he's currently making do in a 2.5g).
I misunderstood the cycling instructions I initially got, and failed to do 95-100% water changes the first few days. I did a couple 50% changes, and then left it alone for about 2 weeks. Now, it's at the point where it's got about 5ppm nitrites and 160ppm nitrates, and the ammonia has gone down from about 3 ppm 4-5 days ago to ~0.75ppm today.
Should I do the recommended water changes now? Or let it be? I'm referencing the below instructions:
"Add Substrate to the aquarium.
Fill the aquarium with water.
Perform a 95-100% water change in 24 hours.
Perform another 95-100% water change 24 hours later.
Perform a 50% water change 24 hours later.
Add any live plants you plan on adding.
If you have filter media from an established aquarium add the media to the filter.
Watch Ammonia levels and Nitrite levels.
The aquarium should be fully cycled in 1.5-2 weeks. 0ppm Ammonia and nitrite indicate a fully cycled aquarium and it is ready for inhabitants."
