My 300 has been in storage for years and I'm just now getting my 125 going after a 2 year learning process with a 55 and a 27. Long time salt water hobbyist from the 70's before live rock. Back then we used UG filters and lava rock or tuffa rock. I still have a bunch and thought about using it for a base in the 120 & 300 with new live rock combined.
I like sumps, deep
sand beds with plennums as well as
macro algae in my setups. Seems to work well with few issues but I have low bio loads too.
