Coralline on powerheads, keep or destroy?

[Falc!]

My tank grows coralline like crazy on every surface except the glass which im so happy about because i hate scraping it off back glass on previous tanks. But all my powerheads get completely covered in a week after a deep clean and i dont want to continue cleaning weekly so i am thinking of just letting it grow. Is it really that bad to let it grow on it or should i continue cleaning off

I would let grow if it’s only on the outer housing and not bothering anything. Unless you don’t like coraline.

Keep it, sterile tanks do not look natural.

Did you say coralline on your powerheads?

gets crusty very fast

I let it go until I’m ready to soak in citric acid for regular cleaning purposes. It’ll get dissolved away and then grow back.
