I'm probably going to get several different answers for this question but here it goes. How many hours do you guys suggest I leave my growlight on over my fuge for my Chaeto? It's a 5w 3 red 2 blue bulb led grow light. I am running it on the opposite schedule as the main tank. I'm using Brightwell Aquatics Koral Lagoon Substrat and also plan on adding a Mangrove in time cuz I love them! I haven't started yet as the Chaeto is new and I don't have my test kit yet but I have Brightwell Aquatics Ferrion to dose that I have heard good things about and want to try out too.
