I'm having a hard time deciding between 6,500K and 5,000K. I have blood parrots, so the 5,000K would probably bring out their orange tones better, but I'm really most interested in what's best for plant growth, without stimulating an algae bloom.

6500-6700k is best for most plants.

I would say 5500-6700 is best. Just don't get the Floramax Aqueon bulb unless you supplement it with like a 10k or something as its really dull light. I bought one a few weeks ago and I hated it so much I made a special trip to Petco and bought a Ultra-Sun bulb, which I love so far.

If you are looking for great plant growth, look for 5700 - 6500K, as this best recreates daylight. But I see you're also looking to get the colours of your fish to stand out. A higher kelvin temp will help you a lot there, even your parrots. Look for 8100 - 10000K for this. I find it best to combine the two, so that you have a balance of beauty and growth, while keeping a very natural look. Your fish will show the difference in colour and behaviour too!

Good Luck

My fixture is coming straight off a reef tank so it already has 2 10K bulbs. I can simply add 2 6,500 or 6,700K bulbs to it, as it is a 4 bulb fixture. Or maybe I should do 1 10K and 3 6,500 or 6,700K. The only problem is that 1 of the bulbs is actinic and soddered (don't know how to spell that) in place bc the clips broke. I'll have to cut the cords and just use 3 bulbs until my dad can come visit and sodder (sp?) another one. I'll probably put 1 10K bulb in that slot as it's not crucial to plant growth so not a big deal if it never gets replaced.

I have a 5000k and a 6500k together on a twenty gallon(24 watts a piece).The 5000k for plant growth and the 6500k for vibrant color.This is how you spell solder.
