Can't buy copepods

[Hightower]

Thanks for all the replies.

It could be Im just paranoid, but I wanted to ensure his survival.

I do dose DT phyto twice a week for the corals. also add a pinch in the refugium. Even cyclopleeze.

Its a 90 gallon tank with about 90-100lbs of rock.

I do have a couple of rubble rock piled up in a corner hoping that would help.

The thing is I cant see them in the main aquarium, but only in my 10gal fuge.

There is cheato in there and red algae, and there is decent a number of them in there visibly. Its gravity fed back to the main tank, so Im not sure if they are getting there. I did take a piece of red algae and put it in the main tank.

Can't understand why they are so hard to buy, and if available why so expensive. They are supposedly something that multiplies like crazy.
