Rofiters

What do you mean how can you increase? How exactly are you feeding them roti's?

I have a bottle of it by Reef nutritions ..i just squirt a teaspoon of it on my powerhead to disperse it for my corals...I notice my larger fish go for it to so i guess you can keep feeding those lil dudes till they get larger and try arctic pods.

you can increase the amount by taking some of the rotifers you have right now and putting them in a bucket of salt water and they will reproduce making a new bucket of "green water". when they turn 7 days old you can start feeding them live brine shrimp. and then at about 12-15 days old you can start feeding them crushed up flakes. hope this helps.
