algae in refugium ?

My new 65 gallon has been up and running for approximately 4 weeks now. It just finished cycling and I added a couple of small fish. As it cycled, I left the lights off. In my sump however, with skimmer and chaeto, my refugium light is on 18 hrs a day. Now it appears I have a diatom growth and some sporadic hair algae on fuge walls, bubble trap, and on base of skimmer. My dt has nothing. I now have dt lights on for 4 hrs a day just to see fish. Parameters of water are ideal.

Ok. Algae is supposed to be in the refugium. What is your question?

Sorry. Question is isn't hair algae a nuisance algae and since its present, should I be concerned? Also, I thought usually after or even during cycle, diatom blooms usually occur. So is it normal or even conceivable that I won't get them in dt since I'm only running lights for 4 hrs? And only get it in sump since chaeto light is on for 18?

It's considered a nuisance because it grows over things we put in intentionally such as corals, and many people don't like the look of it. In the refugium, it's actually serving a purpose.

Diatoms usually comes on and off in a newly set up tank so you don't have to worry about that. Not until its out of whack I'd say. You are right about not having it on your Dt because of the lights you only have it on for 4 hrs. I usually run my lights 12-14 hrs on my sump because I only have cheato.

Nothing is a nuisance in the refugium, except things that eat algae and pods, and 18 hours is not going to make a difference IMO.

Agitating the sand does nothing except move it around. Now if you did a water change and waved the tube over the sand to actually remove it, that's different. Diatoms are a natural part of the tank maturing, but they accumulate in areas of low flow. Increasing flow helps keep them in check. All that being said, if this is the fuge, what's the problem?

Don't touch your sand and try to aim your powerheads up or if you point it downwards make sure its now blowing your sand. How much flow do you have?
