I started cycling my tank with API Quick start that I used in my previous tank. My PH, NItrates, Nitrites, and ammonia levels were all ideal so I added 3 mollies, 2 platies, and my common Pleco who Ive yet to rehome. Today I had a small bacteria bloom a PH of 7.6 ppm and my ammonia was .25 ppm Nitrates and Nitrites were 0 so I did a partial water change probably no more than 25 percent of water. I used a conditioner and a bacteria supplement. Waiting to see if it clears up overnight. Also in my rush to get my tank set up because I had an overcrowding issue in my other tank I overlooked the size filter that came with my new tank. It came with a Top Fin 40 HOB that only pumps up to 200 gallons an hour. I know I need something that pumps no less than 300 gallons an hour. How bad has that rookie mistake set me back and how do I go about starting off with a new filter? Also looking at eventually getting some Harlequin Rasbora once my tank is better established. Yay or nay on those?
