Algae problem after new light

[William Spak]

Hello all!

I’ve attached some pictures below of an algae issue in my 75 gallon 7 year old reef tank.

This issue has happened ever since we got a new light- the blade coral grow. We had no algae before this light. The tank experienced a whole lot of coral growth with the new light followed by the growth of algae.

Water params are normal, phosphates are a tad high.

We have tried phosguard, chemclean powder, shutting the light off for 2 days, manual removal, but it keeps coming back.

Any suggestions?? Thank you!

Your probably going to need post images under white light. I can't make out anything under those heavy blues.

Did you setup the blades to match your original in terms of sprecrum and par? The grows have 1 white diode pre led cluster and are quite power for there size which can cause what your seeing if you’re issue just running them at 100%

Could you explain this further? Also, our white diodes are at 0%
