Freshwater led’s will grow lots of bad algae in the saltwater world such as cyano. Not a good idea imo.
I’m not saying that you’re definitely wrong, but I also think it’s inaccurate to say that a freshwater light will definitely grow algae. There was another thread on here the recently where somebody was pointing out that all our lights claim to be emitting light in a certain spectrum but there isn’t third party testing.
I also see a lot of tanks running under white lights (including my own) that don’t have algae issues.
I think it’s possible that whiter lights can in some cases contribute to algae but I don’t think it’s as simple as saying “x spectrum = algae problems forever” and if the OP does find that they want to change lights they can do so.
