I currently upgraded my 7 gallon nano to a 60 gallon reef with a 30 gallon fuge and a algae scrubber. It has a couple of corals and 4 Chromies currently. When I move in a few months I have a brand new 225 that I am going to be putting everything in to. I was considering feeding live phyto because I want to add more corals and a clam. It will have PC lighting. While doing research on growing my own phyto cultures I was wondering why people don't just do a slow drip in to the tank and constantly top off the growing culture with new salt water. I was thinking about having something cone shaped that drips the culture from the bottom and has an airstone in the bottom for agitation. Would this work or would the culture die off?
