I doubt it would penetrate all the baffles. There is a good amount of grime and dust already on the glass.

And you don't think that'll cause nitrate problems in the tank?

Not with a 1350 GPH pump circulating water in there.

I tried it without the pump and within 2 weeks I had a layer of crap in there so thick you couldn't see the glass.

After 2 days of using the pump 99% of the grime is gone.
