I recently purchased a 180g acrylic which will be a slow build and it came with a practically brand new D&D terminator 2 skimmer when i cleaned this thing up you couldnt even tell it was ever used. But i dont know if that is going to be the best route for my reef although i have seen it on larger systems in the mid 200 gallon sizes, So i ask what is a really good skimmer that i wont have to sell a kidney to get. Could i use the D&D it is rated up to 300 gallons? I also have a friend selling a coral life superskimmer 220 for $100. Im new to the big tanks so any help would be greatly appreciated very much. Thank you.
