What to stock in a 15 gallon fuge?

[Drilled 55 custom]

Doing a diy fuge this weekend. It will be a 15 gallon sump, but the fill line will be about 10 gallons, to allow for power loss overflow protection. Could you help me with these questions?
How deep a sand bed?
lbs of live rock suggested?
would you advise micro algae & how much?
What is cheato? ----thanks all!

If you're putting a sand bed in there it has to be at least 6" deep otherwise there's no reason to have one. As for rock rubble, there's no set amount just put what you can fit in there. And chaeto is the best macro algae you'll find to put in your refugium.

Thanks BL1! None of my LFS have macro algae. Is there an online store you would recommend?

Absolutely, the store of Biff https://www.livingreefs.com/chaeto-you-want-t24752p22.html

She's out right now but should have some in about a month I think.

Yes, I am out of stock unfortunately. You can get chaeto really cheap on Ebay though. That's where I'd recommend you get some in the meantime, until my refugium is replenished.
