I have a 75 gal saltwater tank with fish and coral and this is the only thing filtering the water other than the protein skimmer. seeing if anyone can tell me about it or not? When I got the tank it was established and I was told not to mess with it or change media?? I don't know if I buy that or not as my nitrates are always high.
