I have a 55g 40#sand20#live sand 60#rock 20#live rock. red sea prizm skimmer 2 rio power heads & 4- 65 watt pc lights . I just set up january 15th and already have red and purple corline alge transfering to the base rock. I am thinking about setting up an eco sump all water paramiters are good. I have done the fish only for 2 Years and have a really good LFS but he is really pushing and his tanks are great I guess I am just looking for the pros& cons Thanks
