This is my first nano tank and I am wondering what ideas everyone has and also different mods available. I am looking forward to doing fish and corals in this tank. So far I have taken out the bio balls and plan to replace them with rubble in the next couple days. I also plan on purchasing a nano skimmer, more specifically the one I am looking at is the aquaeuro nano skimmer 2.I really don't want to drill the tank even though I have seen some truly awesome mods involving drilled tank to sump/fuge. I have watched a lot of youtube videos but would be interested in hearing input. I plan on putting the live sand and water in the tank tonight to get it running. I would really like to stick to keeping the skimmer in the first chamber with the heater,so that i have the middle and last chambers open for other options. I'm also interested in upgrading to some leds.

I also plan on buying the tunze nano auto top off system off bulk reef supply and supplementing kalkwasser for the first time.
