How long do diatom blooms last?

[flip_lx]

Simple question since the little fiasco i had earlier i've gotten a rather large diatom bloom all a sudden (brown growth on rock and glass i'm pretty sure is a bloom as it brushes off easily and i suck it up with siphon) i've been running reduced lights (roughly 6hrs a day since nothing but some fry in the tank and i think they are moving out as i do a recycle) and its been going on for a week already

I would say that the most of it should be over in a week or two but I still have the dust on my glass after 10 yrs. I have to take the mag float and clean it off every few days. So you really never get rid of it all. JMO

I agree with Mike. I get it on my glass and have to use the mags to clean. Just one of those things that goes along with a closed system.

I had mine for abt a week and a half and still have some dust on my glass and overflow box.

My diatom problem lasted about 3 weeks, then went away completely and I haven't seen any since.
