Maintenance Routine:
How often do you do a water change? Once every six months to a year or as needed.
How much water do you change? 25-50% at a time, as needed
What do you clean and look for? I make sure all the pumps are in good working order and not clogged. I make sure that the algae scrubber screen is not clogging and the flow rate is still high. I replace the bulbs on the algae scrubber every 3 months with new ones. Once a year I wash the live rock rubble out with saltwater in a bucket. I check the lights every six months and replace them as needed. I feed the tank once every day, and dose phyto in small amounts every single day. I daily check all of the corals and fish for disease or stress.
Why and how I got started in the saltwater aquarium hobby:
I had a friend whos father was really big into saltwater aquariums all through the 90's. In 2005, he asked me if I wanted to watch him feed his tube anemone. He dropped a small piece of shrimp in his refugium and the anemone wrapped around it and pulled it in sooo quick that it surprised the heck out of me. I didn't know it could move so fast! After that, I was hooked for life. So, I bought my first 20g tank that same year and started it and made all of the rookie mistakes while trying to maintain it. After while, I really began getting the hang of it so much so that I expanded to seven other tanks all above 55g in two years! Now I am going to go to the University of Southern Mississippi to try to obtain a Masters of Marine Biology, and hopefully one day a Doctorate. I thought about all of the other things in my life that I had an interest in, but nothing makes me as happy as my saltwater aquarium hobby. So - I have turned my hobby into a life long career.
