my display tank I had crashed on me, came home and almost everything was dead except inverts. Not sure what happened but I decided to sell my entire setup . I still have a extreme black ice that's never made it to DT and was in qt. he's still in the qt. I want to setup another small tank. I have a 4.3 gallon rimless cube. I am debating setting up a innovative marine nuvo fusion 20 gallon. I believe the nuvo is an all in one system, but I'm wondering if anyone has any experience with them. What is needed with the tank ? The filtration system is built into tank? Do I need skimmer ? What heater goes with it ? And what lights is recommended . All important questions before buying it. Any help is appreciated thanks!
