So I have 1x tunze 6095, 2x koralia 750's, a tunze nano wavebox, and my mag 7 return pump on my 75g sps. Roughly 40-50x turnover? I was wondering if this is pretty sufficient and will get me by for at least another year. So far it's been ok, but I'm at the point where I'm looking for possible upgrades on equipments. I know mp's are the big thing now, but before jumping on the bandwagon, I wonder if anyone can explain how their mp has satisfied them. Will the cost actually make much of a diff? If not, I'd probably look into a controller.. Tank has been up for over half a year now. Thanks for any help!
