6105's or 6205's

[mattressman89]

Roger,
I am changing my system over and wanted your opinion on pump size. I currently have a 72"x24"x30" 220gallon tank....upgrading to a 60"x36"x27"
250 gallon tank. I have two 6105's currently and am debating whether to purchase 2 more or 2 6205's. Any thoughts?
Should I put 6205 shrouds on my 6105's?
I also have a 6212 wavebox.....do you think I will need an extension?

Thanks,
Kevin

A wavebox extension is not necessary but would result in a bigger wave. Given the tank width and length, 2 6205 would be the ideal. I would either sell the 6105's or keep them as back ups or you could add them if the tank will be a very high flow SPS tank.
