Just started this hobby 10 months ago when my Daughter wanted a starfish but she gave up 1 week later. I took over and set up my own. Downside was no sump. Everything was external. Just a simple 2 feet tank Along the way, it crashed twice, still learning after my last marine setup was many years back when I was in Secondary School, internet was not much available for read up, no YouTube, no improvise technology unlike now. Only can rely on LFS, farms and books. Crashed many times during Secondary School life and all my recess money was in the tank 🤣 Sent from Singapore Reef Club mobile app
