Hi I am new to salt water tanks been in the hobby for about two and half years now. Started with a 5 gallon that I got already established from someone. Had no clue what I was doing and 6 months in the tank started to have issues. I learned the tank might have been to small for the inhabitants so now I have a 40 gallon Aquatop cube AIO that has been running for about 18 months. I don’t do anything fancy simply do weekly 10 gallon water changes and tank maintenance and so far things have been great coral growing seems to be stable. I really wish someone would have warned me about how addicting this hobby is. I absolutely love it. I really like zoas and mushroom coral they are my favorite.
