I think there will be light spill regardless unless you put the fixture at like 4" off the water. I haven't had much growth outside of my fuge, but still plan on hanging a piece of pond liner on either side.
Well aren't you fancy, I am sure it will work very well.
I definitely don't have that, not related to the light. Your sump area looks like it has a ton of salt spray, and it's on other stuff. My guess is it is related to that. I wouldn't let it build up for the longevity of the light.This is the white powder I am talking about with the Growstar LED.
Any ideas on what this stuff is and if it can hurt anything in my system?
I recommend these for the growstar or any ufo. Super sturdy and have a ratcheting clamp to easily adjust height. Bought on amazon. All I did was drill a screw into either side of my tank center support and placed the hooks on there. If you don't have a center support just screw small hooks from home Depot or Lowes into the inside top of the stand and hook them on that. If you don't have any wood on the top of your stand, buy and cut a 1x3 to length and screw each end into your end supports, then mount the hangers to that board with hooks. Suspending the light is way better than resting it on anything for a variety of reasons (safety, heat control, etc)
If you scroll up I posted my results, it kills it. 2x growth over my par38, having said that, I'm not sure that a light alone will solve your issue. You need to manually remove all of the gha from your fuge so that the chaeto can establish itself as the dominant macro in there.
Your chaeto doesn't look like it's dying but rather accumulating detritus and maybe some cyanobacteria/algae. I have run gfo with chaeto before sure, just realize they are competing for phosphates. I've only done it when my phosphates were extra high for one reason or another, then took the gfo offline and let my chaeto handle it at normal levels.Is my Cheato dying? Also is it safe to run GFO when trying to grow macro algae such as Cheato?
