Got a new grow light today to put on my Refugium and replace the CFL bulb. I'm hoping this will spark some growth of my chaeto. I tested my PO4 today, 0.12ppm and after a 30g WC 0.08ppm. No shortage of nutrients so I'm hoping this light will help actually grow it. I'm hoping it's not too late for the remaining chaeto ball. Here are a couple pics.

Thanks! I will let you know how this goes.

good luck!

Thanks. I'm hoping his chaeto will still be alive enough to grow or may have to pick up a new one to test the light.

i got a small ball of it months ago and have it in the back of the main tank. it does not grow or die. i do need more lights. right now they are over the middle of the tank where i have a few frags, but when the fish swim closer to the glass you can tell the lights are not hitting them any more. once i get more lights i will make a stronger effort to grow the chaeto ball. i am just glad it is not dying.

What are your parameters at?

So unfortunately my chaeto ball withered away just in time for my new light. PO4 is at 0.13ppm so I’m guessing it was the light. Need to track down some local chaeto to try again :sad:

Im supprised yours melted. I find they are generally tough. I dipped a newly aquired one on after breaking it up into small flattened pieces in CoralX and flatworm exit, then rinsed in ro water and final rinse with new salt water andbleft it soaked in old tank water on a container before putting it on tank the next day.

I just use regular homedepot lights. Here's what happened to mine though. One i made a drilled rubber maid container ( a former algea scrubber container) and pumped water to it with the cheato on the container then it drains to the sump. This cheato melted. So next i just placed it directly at the sump, decent flow and seperated it with a eggcrate with gutter guard. Started with a tennis size ball and it grows quick.

Hope yours grow
