Hello, I’m new to reef2reef but have been keeping aquariums off and on since I was a child. With my job I’ve gotten back into reef keeping because I love it and it relaxes me. I just bought a used 90 gallon Marineland tank with some live rock,fish,and coral. I’ve been dealing with some Dinos which have receded a bit since I increased brought up phosphate and nitrate by feeding. I have also been dosing bacteria. I was just wondering if anyone could identify the type cause I was thinking of buying a UV Sterilizer.
