Hi all! I've made a few tank threads before, but I would like to start this one from day one of this tank. I have previously had a 5G reef then a IM 20G Fusion. Today, I finally jumped up to a 40 breeder and I now have my first 20L sump. I will go more indepth with a post tomorrow or later this week, but after taking 5 hours to change from the 20 to the 40 I will just leave you with pictures for now. The first picture will be of the 20G and the 2nd of the 40B I just got set up today.
