Looking for high growth rate t5 combo

Just replaced 2 of the bulbs in my 4 bulb t5 fixture to ATI Blue +. Now the other ones need placed. I do want a slightly blue look however looking for high par high growth combo. any suggestions?

 

I had 2 blue/2 daylight for a while and it did good, then went to 2b/1d and 1 purple...did great...now I'm at 3b/1d

 

Get 2 ATI Aquablue Special. If you really want them to grow replace one of the Aquablues with a GE 6500K.

 

what about one fiji purple or atinic and 1 6500? what about ge 3k? says it brings out oranges and reds?

 

im so torn from what to get. I wish I had money to buy several bulbs to try out but I dont
I am concerned with the look of my tank yet concerned with whats best for corals. So many combos running in my head. Only forsure thing is the 2 blue plus bulbs.

was thinking
Blue +
Fiji Purp or giesmann pink or other atinic bulb
Blue +
ATI Aquablue


or
Blue +
Some sort of daylight bulb best for coral growth
Blue +
Aquablue

or
blue +
Blue +
midday bulb
blue +

 

The more blue your bulbs the slower your growth rate in general. If you want high growth rate go for 4 ATI Aquablue specials in the fixture. Won't be very blue but your growth will be awesome.

What two bulbs will you not be replacing? Can't really help you without knowing this.

 

i just changed mine to

1 ati purple plus
1 ati aquablue
1 ati blue plus
1 ati aquablue

 

If you want good growth and color go with the second selection with a GE6500K for you daylight bulb. Placement front to back to get the most blue look.
Blue+
Aquablue
GE
Blue+

The 3000K will brown out your corals with that few bulbs.

 

Question about the GE6500K: won't that bulb lead to increased algae growth as well? Or is this negligible compared to the increased coral growth?

 

Not in my experience. Excessive nutrients is resposible for algae growth. The color temperature of midday sun in the tropics is 5100K.
