dun think there's enough aeration just from the OHF.
seriously ask you to remove the gravels.
yes....BB will more or less thrive in gravel...BUT so do other harmful bacteria....

if you wanna keep your gravels, you have to be extra diligent in water change....
and 25-30% change is definately no enough....unless you feed your fish teeny weeny bits of food once a day, which i doubt so......heehehehe...

gee, u r quite gungho to go into gravel without knowing the shortcomings!

like g-string said, bad bacteria could thrive there. If the gravel layer is deep enough and anerobic region develop, anerobic bacteria (in the presence of carbon source) could produce hydrogen sulfide gas. This gas, when released into the water, is extremely toxic to fishes. Thus it is recommended to clean the gravel frequently to clear away such anerobic region and waste.

that's why I said it can still work but need more effort.

i see.... i read on an acticle on anerobic b4, but tot it only turns unused nitrate back to ammonia, din noe it can do so much harm...

but since i already started, den might as well i be e guinea pig lor...
see how it goes lor... try to reduce e nitrate level see how, but anyway nothing has happen yet... thanks alot g-string n square_guy
