Cloudy White Water: Bacterial Outbreak?
I have a 20 gallon tank, with 48W T5HO lights, 10 Neon Tetras, 4 Red Cherry Shrimp, and 5 Assassin Snails. Feeding is once or twice a day, usually flakes but I go with Brine Shrimp or Bloodworms once a week.
I dose Excel every day, 2.5 ml. I dose Flourish Iron and Comprehensive supplement the same amount, twice a week. I dose 20 ml of Nutrafin Cycle during my weekly water change.
My nitrite and ammonia is 0. The outbreak seemed to have happened after doing some rescaping so I thought I might have released toxins from the substrate but there's no nitrite or ammonia.
Last week I performed two 50 % water changes and went dark for three days. That brought the tank back to normal but this week, it's back to being cloudy.
All I can think of is that my lights are on too long. I put them on around 7:30 am and they're on for about 12-14 hours. Since I'm not home until 6-6:30 pm, the earliest I could turn them off would be after around 11 hours. Maybe I should invest in a timer?
The tank is two months old and this is the first time cloudiness has become an issue. I didn't think lights would affect bacteria, only algae but it's definitely a murky white, not brown or green. The critters don't seem affected though.
Any thoughts would be appreciated. Thank you.
