55 Gallon SW need help

[Cerianthus]

I'm using 2x54 watts t5 bulb which is white and blue color. When both of light turn on water look clear but when only white bulb turn on so my water tank look yellowish.

I also think maybe my light make the water look yellow color.

Can you check color temperature in your white bulb. Perhps it maybe 6000K or less which may give tinted look.

I use natural seawater which is brrown/yellowish and smelly to begin with but not for long under my 10000K (white daylight) & 7100K Actinic (Blue) & filter + PS.

Whenever I disturb my susbstrate from time to time (increase in free floating microbes for my inhabitants (fish and corals), water becomes bit turbid but not for long. And Im only using Millenium 3000 on 45G (similar to good old Whisper 3) for now. Will eventually hook up couple of Classic Eheim. Oh yah! have been running Seaclone (not the best protein skimmer but working) since I set up the tank about 10 days ago using mostly natural seawater.

Are you running PS on your tank??


btw, if can obtain coconut carbon in Malaysia, try it!
