[KVYA]

is a 30 watt led flood light good for a 6.5 gallon reef tank?

What about this? I was thinking of breeding opae ula (volcanic shrimp) and wanted to have caulerpa for cover. Would it be enough to grow macro algae?

ah. a refugium bulb. yea may even bee too much ive never metered one. yea just check its full spectrum. honestly you can go with power compacts too, cool white and warm white.
the phillips par 38 led is also a good choice but it is VERY bright. so dimmable is a plus

Nice. I don't think I have a fixture though that can fit a bulb that big

they make a small one the same color. also look for the smaller Par 38 for planted tanks.
