1. sir peter, ok na ba yung 2bulb sa 4ft na tank?
ok na bro sa 4ft tank.
2. whats the difference between the 70w and 150w eh parehong 20,000k naman?
yung 20,000k ay yung kulay ng light na lumalabas sa bulb.. which is bluish. tapos yung 70W and 150W is power output naman.. 70W gamit natin for shallower tanks (20gals, 35gals).. tapos 150W para sa tanks with height gaya ng 75gals and 150gals.
3. bluish ba yung effect nyan?
yup.. kasi 20,000K sya
4. pa quote naman yung whole set for 4ft tank plus wiring and casing
around 9,000 kasama 2 na 150W PAR38 20,000K mh bulb w/ ballast and aluminum fixture w/ wires/plug.
similar sa ganto yung setup except for the fans:
