Kurt are you using a RODI?

That's incredibly fast for diatoms. With that kind of diatom growth, your

What about the sand and the gravel, how's it looking? What's causing your
turbos to die?

Yes, the turbos definitely make paths on the glass. I think the hermits
killed off a number of turbos for there shells, and then it took me awhile
to figure out that when a turbo lands on it's back, it can't get up. I
now turn them back over when they accidentally get bumped by the algae
magnet. I also feed my giant hermit once a week to keep him from preying
on the turbos.

The sand is okay. There are some brown areas, but between the blenny and
2 fighting conchs, it gets turned over frequently. I've been slowly
adding more sand because I only have a 1/4" inch in spots. I also have
lots of debris from turbo shells, etc. I've been removing a few of these
whenever I do a water change to keep the sand sifters happy.

I think it's sherlock homes reasoning time: "Eliminate all other factors,
and the one which remains must be the truth."

Phosphate? I'm thinking the phosphate reactor is working well enough to
keep the hair algae under control, but it's still not good enough for the
diatoms.

It seems that the only time the diatoms get knocked back is when I change
media in the phosphate reactor. I get 2-3 days of clear glass, and then
I'm back to the usual. It keeps the hair algae from growing for about a
month. I was thinking that it was silicates, but now phosphate seems more
plausible.

I'll order a more sensitive phosphate test and keep working on the fug.
