I usually always get a growth of Diatoms any time I add a substantial
amount of liverock to a tank.......even if rock is cured and removed
form one tank to the other, I still get diatoms to appear shortly
there after. I no longer get concerned with diatoms, as they never
seem to hang around very long anyhow.

What do yu have for nitrate export? Macro Algae? Xenia?

I have a really bad case of diatoms (or algae) growing. I added the
lights and 30# of rock a few weeks ago.

I was expecting my nitrates to be off the map, but they aren't bad.
Maybe about 30 ppm which isn't good, but good for me.

I switched to using distilled water until I get my RO/DI filter setup.
So, I don't think that it's silicates, but I have no way of testing for
that.

Last water change was two weeks ago, so I'll go ahead and mix up some
water.

My phosphates are better. Not great, but I've been using phosphate
beads and the levels have been settling.

I also have lots of bubble formation. I assume this is O2 from
photosynthesis.

So, how do I curb the growth?
