Hi all, new to planted aquariums and to this great site!
I started by buying a 37 gallon tank (22” deep, minus a few “ of substrate), putting down some carib eco complete substrate, and got planting. My goal has been to do what I guess would be considered a “silent cycle.” Basically I just planted several, fast growing plants, mostly stem plants, and provided them with root tabs and seachem flourish, as directed. I also added a somewhat decent LED light (keeping it lowtech, no CO2, plants only need low to moderate light). It’s been just one week now, and I detected maybe 0.25ppm ammonia, somewhere between 1-5ppm nitrite, and ~5ppm nitrates. I haven’t added any source of ammonia, so I’m thinking that the tank is sort of doing it’s thing with the plants alone? Im wondering if I should do a small water change soon if the nitrites don’t go down and if ammonia climbs? I did also add some API quickstart once I saw those levels, to see if that would do anything to help speed up this process. At this point, if plants continue to grow and if nitrites go down, would it be safe to add just a few fish at first, after a partial water change?
