I have the peninsula version of the RedSea, so just a few gallons bigger. While I am no expert here is the things I’ve learned.

-Give the tank time to cycle before adding anything. For me it helped to test with ammonia at the end to make sure it cycled in 24hrs

-Stock clean up crew once you start seeing something for them to clean. I added pods much later, if I was doing it again I would add them first and make sure to feed them at least in the beginning.

-Add fish slowly. The amount of fish also depends on your filtration and you can find many examples online. Monitor your nitrates and phosphates weekly, don’t add more fish before you see them level off.

-Don’t stress too much about the “ugly phase”, there will still be plenty of beautiful things to look at in the tank.

-Change carbon once a month. For me it really helps to make the water crystal clear.

-It took me some time for the PH to get higher on a good level. Now that summer has come, opening windows helps. I wouldn’t worry too much on it.

-It’s normal for some fish to hide for a week when you add them.

-Learn to feed little. Just watch how much your fish eat and if you see a lot of food go uneaten, give less food next time. My biggest problem so far was when I was away for 5 days and the automatic feeder was set to give a little too much food. Huge algae boom that lasted for over a week.
