Nice man! looking great!
Nice... What are you using for filtration? I also have a 20g that's about 3/4 months old and gradually adding corals and such. Have a hang over filter and want to get away from the filter but afraid it make things bad. I'm a newbie.
You could put some Seachem Matrix in the aquaclear30 in combination with GFO, then you would be able to remain skimmerless, sumpless, and fugeless... I however think at some point, you will need to find a way for DOC removal, might work early on, but whether biological, chemical, or mechanical, whatever goes in, needs to find a way outThe idea is superb, looking forward to seeing this one mature!!! I also have some sweet freshcut sps when the bug bites you, lol...
Looking good!
