Wrgb2 on 10 gallon

I have a 11 gallon cube tank with a WRGB2 30cm. I use it at 50% intensity for all channels, and still feel it slightly too high. Everything grows well including Montecarlo carpet, but some of the higher plants (ludwigia super red) keep having green spot algae on their leaves and just can't get rid of it. Thinking of reducing it a bit and see how it goes.

So I'd say it's safe to start somewhere ~50% and adjust.

I'm waiting to see what others say here too.

I have a wrgb2 on a 5 gallon tank (no co2). I run it around 80%. I get a bit of algae on the glass but none on the plants.

Oh good to know, is it a cube tank and is it the 30cm.wrgb2?

It is a standard rectangle aqueon 5 gallon tank; it is the 30 cm wrgb2. I've had on the tank for about 2 months but this morning i reduced it to 70% (70 red; 49 blue 49 green); to see if that reduces the algae growth on the glass. Of course i'll leave it like this for at least a month to see what happens.
