Hello Everyone, I've got a problem with my new 128 gallon tank, The tank is running for 1 month now. Before 3 days i bought full Pressurized Co2 System from Tunze With Ph/Co2 Controller. And i Added a normal Dose of Seachem Flourish. After the dose one day the water turned white cloudy and today its going to red. I Have lighting fixture with 2x 39Watt T5 (14000K) Running 12 hours a day, and 2x 250Watt HQI (5100K) Running 10 Hours a day. Should i shutoff the lights for 1 week? or do water change? I'm little confused. *NOTE* Ammonia - 0, Nitrite = 0, Nitrate = 5~10, Phosphate is less than 0.25. Tank Information is on left (Tank Info). Thanks.
