| Re: Is a skimmer necessary on a 150 gal tank? Skimmers aren't "required" on any tank but they go a LONG way to helping GREATLY increase water quality. They remove DOCs (Dissolved Organic Compounds) 24/7 while you do other things. Some people (me included) can get away with water changes alone on smaller tanks (10g & 12g units here) but the larger the tank the MORE a skimmer does for you.
Honestly I believe that a skimmer is one of the MOST important parts of a Reef Tank for long term success. |
