I feed every few days. With most shrimp, it's easy because they'll just eat algae and biofilm if nothing else is available. Ghosties are a little different though. They don't eat much algae, and are constantly scavenging for food. I would feed them a small amount every day so they don't eat one another. I have literally seen one ghost shrimp rip another in half and devour it in a matter of minutes. Creepy!
I do a WC of about 1/4 of my AquaView once a month (or so). You should probably do every two weeks with ghost shrimp. I'm going to increase the frequency on mine here shortly because I'm impatient with my plant growth and want to start dosing Flourish Comp and resume dosing Excel every few days. I stopped for a while to give my crabs and shrimp a chance to get adjusted.
You should start a journal and post pictures of yours
