You currently have 2 daylight bulbs.... You could go with one and be alright....

You will notice those with more colorful corals run them more on the blue side 14k+ .... The GE bulb is in the 65k range, it will give you growth but colors will lack more than they do now with only 4 bulbs.... In a 6 bulb set up, it would be easy to cover up the yellowish hue put out by it but not in a 4 bulb set up.....

Are you sure it's a ati true actinic or just a actinic bulb? There's a difference..

dump the unknown 10k bulb for a ati aquablue

dump one of the true actinic for a ati blue plus

dump the ocean sun for another ati blue plus....

Save on buying LEDs for now... But even I put some on my 4 bulb set up to get more blue and pop....t5s just don't make colors pop like LEDs but the bulbs your currently running wont help colors...
