Okay so I'm new to saltwater all together so I do apologize! I have a biocube 32 and trying to get my filtration to be as best as possible. I already have a bag of bioballs and a bag of matrix 110 in there as well . Looking at bioreactors but not to sure about it because I don't have any room to mount it outside of the tank .what are some options I have for optimal condition. Tomorrow I plan to do a water change and get whatever the white film that's built up on my pump and chamber walls off so hopefully the water will be cleaner. Hopefully I'm doing the right as said before I'm new to this ant just trying to do what's best . Any help or advice is greatly appreciated and thanks in advance!!!
