Hi. I have a RS reefer 525xl. 5ftx2ftx2ft 139 gallons. Im currently using 2 maxspect f350x gyre. One of them having issues and im getting tired of the problems they've been causing. I wanna change out my flow pumps. What do you guys suggest? Should i go with 2 reefwaves and which models. Or should i go with mp40 and how many? Placement for these pumps? Attached is a pic of how my tank looks. Please help anyway you can. Any suggestions or input is appreciated thanks.
