Best product to add heterotrophic bacteria?

[DE FISH]

I’ve had this white fuzz growing under my rocks for a while now and need some good heterotrophic bacteria to outcompete it. it isn’t killing corals it’s just unsightly and sticks to the glass very annoying I have mb7 in the fridge but don’t think that contains heterotrophic bacteria. So what’s the best bottled product to go for ?

nitrates 1ppm (i do dose nitrates to the system just done a large water change so will be raising them to 2.5 - 5ppm)
Po4 0.08

[Who me?]

MicroBacter 7 and MicroBacter Clean. Dose both daily for a 7-10 days, rock will be clean.

And yes, MB7 contains heterotrophic bacteria.
