oh.. understand. so.. i got 1 arcadia blue actinic the other normal FL. can i change that to arcadia marine white?

arcadia white FL is not exactly white- its kinda orange.

arcadia doesn't measure their lamps in kelvins- but in CRI.

Sure u can change the actinic to another white- but from my view- some corals do benefit from actinic 03 spectrum. Honestly, your opening pandoras box of lighting- espeacially for corals.- you're looking at around 4-6 FL tubes of white+your choice nos of acitinic tubes for any long term success. & with FL tubes u need to replace on a regular basis.

If u do intend to stick to FL then -

have a look at keong seong at havelock for a variety of FL tubes. Its written on a list on the pillar near the counter. U can also ask them on recommendation. Be prepared that 3ft FL tubes are actually more or the same price as 4ft lenghts. Their prices are OK.

They have 10,000kelvin, & 20,000kelvin coral sun tubes if u wanna spend-.

Although 2x 30w FL over your 3ft won't let u keep much corals.

It works fine for a fish only.

And 1x 20,000k tube does not equal the same as 4nos x 6500k.

still need to stick to wattage per gal.- that's why u need to plan ahead for the inhabitants you intend to keep.
