Why can’t I grow Chaeto?

[Mmcghee102485]

I have a Reefer 350 and have tried multiple times to start a refug. I have the nutrient to support it. I’m using a Tunze submersible light. I know it’s not the best light but have read reviews of people with success. Could it be my light? I run light for 6 hours at night. Chaeto does ok in the beginning then starts to die off and turn color. Looks like it wilts away....Thanks

Have you tried dosing trace elements? I had the issue with chaeto till I started chaetogro

I'd run way longer than 6 hours in that light. Also add iron. That's what seems to be the trick for most people

Hi I have the same set up, RSR350 with tunze light. I have good success, but I run my light for 12 hours.

I have an off period of 6 hours to give my light a break lol

My chaeto took off when I added a pump underneath it to help circulate the water a little more.

SAME

I keep my Kessil light on for 12 hours, added a ton of flow, and started dosing iron. still, NO GROWTH. I also have high nutrients.

stupid chaeto

I had the same experience but chaetogro worked well. Iron on its own didn’t seem to do it. I now have the big container of it on a doser for a couple ml/day. Not sure what was missing, but the change was dramatic and clear from dying to growth. My last harvest.
