I need another filter to complement my Eheim 4+ 600 on my 75 gallon mbuna tank. Don't want to use an HOB because I'm trying to keep it as quiet as possible. Eheim gets about 4x/hour and I'm looking for a total turnover of about 10x/hour. Wondering if I should just go with another Eheim or maybe a Fluval would complement my current set up better. Suggestions?
