I'm curious to know if this is what other people have found happens.

I'm 3 weeks into my my new tank, and I'm just starting to get diatoms. Next comes cyano. Bring it on ,I've beaten it before, and I know how easy it is to get rid of!

This is EXACTLY what I'm going through. I was so stressed initially, but I'm seeing improvement with a reduction and modification of my lighting period.

So instead of having Halides and Actinics at the same time of day, I alternate. So it starts with Actinics, moves to Halides with Actinics off, and then when the Halides go off, the actinics go back on. Usually there's a bit of an overlap, but I went from horrible everything-covered cyano to now there only being a few patches, and it's completely gone at night. All the diatoms are non-existent - it's taken longer than I was expecting and I RARELY feed anything other than Mysis with Selcon/Garlic (alternating) and MAYBE a few pellets, the more I reduce the food and high light, the better things seem to go.

I'm actually HAPPY with my tank again, huzzah. Now I just need to slowly remove the sand until I'm down to just a teensy bit and I'm good to go!
