Best bulb/light for Chaeto growth 2016?

[ps2cho]

I am currently running a 27w PAR30 that is designed more for corals I believe...It grows the Chaeto, but not very fast. It only grows it from fist size to grapefruit size in 4-6 months. i've only harvested it twice in a year...and I keep nitrates and Po4 around 5ppm and 0.04-0.08 respectively.

 

Is it just a bulb replacement with something like this?

Or any other suggestions? Not looking to break the bank for a minor impact...

Coral compulsions refugium par 30 works well.

 

I tried the cheap ebay one and hated it. They are weak.

 

i can't promise light is your issue though, there could be other factors slowing its growth such as trace minerals.

+1 to the light above. I use 3 of them on for 16-20 hours a day.

Honestly, I diy'd a light box from hardware and velcroed it to the back of my 29bc with a 40 or 60 watt equallivent cfl bulb and almost once a month I was splitting my cheato and taking about 2/3 of it to lfs for credit.

I just use a cheap LED home depot light in a cheap metal clip on reflector. I think it was under 25 bucks for everything. I run the light 24/7 and was trying to get rid of the chaeto as I have a lot of macros in there. Well it just keeps appearing so let it go. went from a few strings to a softball in a few months.
