seen a couple threads on this but wanted to get some thoughts. I run a tunze 1073.05 right now and am looking at the varios pumps as I’ve had the tunze for many years and lately even after cleaning it seeems to loose its umph. Will the varios 2 be enough for my 250. It is only 54 gallons with a 11 gallon sump. The plumbing is straight down from the overflow to the return so no bends etc. it will only be feeding the return. For the tank I am running an mp10 right now but just got a nero 5. I don’t want to push too much water to fast through the sump/Refugium and skimmer. Thoughts?
