Just installed the FMK on my 92G corner tank and it is reading 228 GPH on the return pump. Tank is in good shape, but concerned about low turnover rate of tank at less than 3X per hour. Been up and running for 4 years.
Looking for advice on if I should upgrade to a DC pump with turnover rate closer to 5-7X. If so, which pumps are the most compatible with Apex controller?
Thanks to all that weigh in on this thread.
