So last week I cleaned out, changed the substrate on, and upgraded the equipment on my 20-gallon formerly neglected tank. One of my HOB filters broke in the process but the other one survived and its media was kept in tank water throughout the process. I had somewhat of a mini cycle when ammonia was briefly detectable in the tank. I decided to wait a week to even out the water chemistry, and to allow time for the new canister filter I bought to get its kinks out(I am keeping both the canister and HOB on at the same time for at least another month). Anyway, yesterday I tested the water and here are the results: Ammonia: 0ppm Nitrite: 0ppm Nitrate: 8ppm I think I am ready to add fish, but if anyone sees something I'm not seeing please let me know. Here is the stock I am planning: 4x Peacock Gudgeon 8x Lemon Tetra (one is currently in the tank from its previous iteration) 5x Amano Shrimp 2x Nerite Snail As to what to add when, I was thinking of adding the 7 lemon tetras tomorrow, and then the amano shrimp and snails later in the week as I have some algae I need cleaned . Then in two weeks I was planning to add some to all of the peacock gudgeons depending on what people say. Does this plan make sense and give the tank appropriate time to adjust? Thanks in advance!
