Kelvin choice for CRS and plants


Hi All

Hope you are all well, just wanted to pick everyone's brain for advice.
-I have a AquaOne AR-980 215Litre/55Gallon tank aim to be planted with focus on CRS (and potentially a few fish)
-Setup on the 13-Oct-2012 with 3 bags of ADA Amazonia New
-Has a medium/large piece of driftwood with Anubias, some Blue Stricta (and a violet version) and allot of Micro Brazilian Sword
-Water testing on 12-Nov-2012 shows it is still in the Ammonia part of the cycle despite it being 4 weeks (think its the ADA) so added a DIY C02 setup through a powerhead to try and help out the plants and cycle

Question is the hood contains 3 x T8 90cm tubes.

I had one blow out so have replaced it with a 30W AquaOne sunlight tube rated at 10000K.
In there already seems to by a red one I'm assuming 15000K and another white one rated at 6500K.

It seems that even if I replace them all to 30W tubes I will still be under the ideal Watts per gallon 09W/55G. But the main thing is I've heard that plants and CRS only like rough 6500K-10000K, however I wanted to change one of the tubes to a 20000K AquaOne marine blue tube for aesthetics, will this affect the plants and the CRS?

Your help is appreciated.

Cheers
Will

A 20000K bulb is very blue; it will essentially be unusable by plants. It should not affect their growth (nor the CRS), but you are essentially "wasting" a bulb.

I am not sure of the exact dimensions of your 55 gallon aquarium (I am assuming ~21 inches), but even with three T8 bulbs, you will be effectively low light at substrate level. Using one space for a 20000K bulb will essentially make your aquarium only suitable for low light tolerant plants.

Thanks for the advice, I thought as much.
Will ramp up the other 2 to 10000K as well for now and look into LED lighting next.

Cheers!

you can do with anything from 5000k to 10000, plants will like them. 10000 will be bright, clean white/blue light, but washes out plant colors a bit. 6500k is a popular choice, greens will be richer but the light is a warmer yellowish color.
