Tank of the Month - March 2005

Dan,

I have a 30g with 4 39w T5 bulbs over it.

The corals grow well and fast.

My problem is color.

I have pink and red corals that look great.

It is the purple ones that turn brown and stay brown.

For bulbs I have:
1 x 10,000 Daylight
1 x Giesmann 6,000K Daylight
1 x 460nm Actinic
1 x Giesmann Pure Actinic

Would you mind giving me your recommendations on bulb selection? I am not as worried about appearance as I am coral color.

Also, I am going to try and start dosiing amino acids to see if that helps.

Thanks in advance,

Bruce
