I treated the tank for cyno, and yes I did have that too. It was more red and stringy. It's all gone now but I'm left with diatoms.

I still feel it is diatoms, and is just a cycle due to the large bioload and the lack of maturity of the tank, with so much dry rock, and without seeding it for the first 6 months, it is basically still dry rock, you need a small bioload, be it a few fish or a piece of raw shrimp, to seed that rock.... it isnt something that will go away in a week or two, and as long as everything is healthy, I wouldnt give it too much thought, it will sort itself out on its own.

Sounds good, I'll just keep on track and let it take care of itself. Fish and corals are doing fantastic.

I'm guessing they would stink, like a skimmer, wouldn't they?

I've posted a picture, and here is another one.

That is the same junk that was ALL over my sand to. I siphoned out what I could get at & after topping up my pellets it was gone in a few week.

Good to know Greg. I'll continue siphoning and get my pellets up to 4 cups and hopefully things will start to change.

Will GFO work instead of pellets?
