ReefMat Sizing

[RoanokeReef]

Evening, was wondering on the ReefMat sizing if I should go by GPH or tank Gallon size or both they have listed. Dilemma is I’d like to go with the 250 model which is rated for 900 GPH since the physical size is smaller however my tank is over the 66 gallons, Opus 300 is 69g with 14g sump. However the GPH is only 525. Would I be ok with the 250 or should I go with the 500? Thanks much!

If you're able to fit a larger model comfortably then I would suggest it since you can always import a larger model to a bigger tank in the future + it's less work on the motor + maintenance required since the rolls are larger for a marginal price increase.
