I try to leave my refugium alone for the most part. I don't touch the rocks or the bottom. On occasion I will harvest some chaeto, caulerpa, or red macro algaes as needed. I do clean the front glass about once a week but that is about it. All of my actual live rock for the system is in my refugium so there is a ton of life in the refugium that I let balance itself out. I feel that cleaning the refugium would disrupt the balance of life not just with the macro algae but with all the microfauna that is thriving in this tank. As my displays have been doing well I have opted to keep my maintenance with the refugium the same. The only recent change I have made is a light upgrade for one of the lights that needed replacement back in December.
The MP40 is starting to get a little clogged up so it will need a trim. Don't ask me why but the Botryocladia (Red Grape) macro algae decided it likes to grow on the MP40.
