All my duckweed has doubled in two days.
Easy 80% of the surface covered.
Unknown rotala has grown an inch.
These LED's have made a difference.
BBA has not been pearling either, like in the past.
It is an experiment again.
This new burst in growth is running @ 25% on the old UV channel.
When the UV's @ 385nm were at peak performance no BBA.
As they dimmed and degraded BBA at highest levels in tank began.
Maybe the swap to full spectrum will help?
When new the UV channel ran at full 700mA.
New fixture experiment is a 7 led heatsink disk.
It includes 3 full spectrum and 4-10K @ 24VDC @ 700mA.
It is much more pink than I would like @ 50% and under.
Once over 50% intensity it looks great.
Intended to use these on a 75 gallon newly acquired tank.
Building 3 fixtures with two disks each. 42 watts per fixture.
126 watts for the entire tank. I always over-build and dim though.
I don't try to target high light and use ferts based on water testing.
I have managed to avoid the algae farm method.
More 3 watt LED's coming, "The China Wait Game"
