Chaeto not surviving

tzylak · 05/22/2019, 09:13 AM

I have the tank for six years and it's been established for 15+.
In my sump I have fudge where I've been successfully growing chaeto for 5 years. In the last 6 months the chaeto died (3 separate times!!) smothered by some slimy algae. I used to use Sylvana 65W, 800 lumens, 5000K LED, but that's been discontinued. Now I use Cree 65W 680 Lumen, 5000K LED. - In both cases the light hovers 6 inches above the water.
Would that make a difference?? What else could cause the chaeto failure?
Help!

Oh, and a month ago I added the second pump to move more water thru the growth. Evidently that did not help.

Did the problem start after changing the light or before?

What are your water parameters?

I get the same growth on my Chaeto after leaving the sump light on all weekend (tank is in my office at work). If I give the sump 24 hours of lights out the growth mostly goes away and the Chaeto seems to recover fairly well. I assumed it is cynao and was blocking the light from entering the water column. I curious for others to chime in with their opinion.

Wow!! I had the light ON 16 hrs/day and it seemed fine. I remember increasing time to 20 hrs and that's when the problems started. I'll reduce and see what happens. THANKS! Tom
