How to keep artificial rock clean?

[240gallons]

I converted by 125 to officially tank. I put artificial Walt Smith Rock in. I don't think I can pull it out and bleach it. I've also used copper in the tank so no invertebrates.

Other than scrubbing with a brush is there any other way to keep the rock clean? There is no hair algae but just Brown slime build up.

There's got to be a magic pill out there ..lol.

What about chemi Clean

Less light

But withstanding biological control, and assuming you do not intend to have extravagant nutrient control on a fish only tank, reduce the lighting to the minimum needed for viewing (and fish sanity).

And "brown slime" may indicate that it may be a bit more involved than that (i.e. dinos or cyano)
