SnowboardKid26 Posted October 23, 2006 Share Posted October 23, 2006 So it seems that for the past month my chaeto has been shrinking instead of growing. Now a bit of nuicance algae has popped up in my tank, so somthing is wrong in my refugium. The only thing I can think of is that maybe something is eating it. The only animals in my fuge are a couple of astreas, 2 hermits, 3 nassarius snails to keep the DSB stirred, and a pencil urchin that got to big for my tank. Would the urchin possibly be eating it? (flame) That would be the last straw for him..... I stopped dosing iron for the time being, but any other help would be appreciated. Quote Link to comment Share on other sites More sharing options...
nu2reef-n Posted October 23, 2006 Share Posted October 23, 2006 I dumped an urchin in my 'fuge, and the darn thing scarfed up all my macro algae. It was a collector urchin, and it paraded around the 'fuge with a floating thermometer and clumps of macroalgae all over it. Quote Link to comment Share on other sites More sharing options...
Barleychown Posted October 23, 2006 Share Posted October 23, 2006 What is the bulb over it? Quote Link to comment Share on other sites More sharing options...
spayne Posted October 23, 2006 Share Posted October 23, 2006 What is the bulb over it? Yeah, I second that. We used to kill chaeto until we got a daylight CF bulb at WalMart. No problems getting it to grow now! It seems like it's a "Lights of America" light. Jay would know more about the brand if you're interested.

SnowboardKid26 Posted October 23, 2006 Author Share Posted October 23, 2006 I have a 18w 50/50 cf over it that came with my light. SHould I look for another blub? Quote Link to comment Share on other sites More sharing options...
Chief Posted October 24, 2006 Share Posted October 24, 2006 Look for a bulb that says "Daylight", "Sunlight", or specifically states the kelvin rating. You are looking for something in the 5100K to 6500K rating. There has been some debate as to which kelvin rating grows plants better. I have been using the 6500k lights and just had to remove about 7 gallon sized baggies of cheato from my 55 gallon fuge. Jay Quote Link to comment Share on other sites More sharing options...
Barleychown Posted October 24, 2006 Share Posted October 24, 2006 My bulb is also a daylight CF floodlight. Quote Link to comment Share on other sites More sharing options...
