So my Bubble Magus Nac7 atman 2500 pump only stays on for a few hours and completely stops. Gave the skimmer and pump a good bath and replaced the pump impeller and shaft and still the pump doesn't stay on at all. Getting un-wanted algae growth and my sps are starting to hate me with po4 slightly going up. Should I replace the pump or should I use some of my tax return on a Super Reef Octopus XP1000 Space Saver using a Bubble blaster pump? $80 fix or $430 upgrade? Tom from Seaside, upgrade for the Nac7 is not for another few months. basically retrofitting the atman with a sicce psk 600 pump.... So should I do a temp fix and replace the pump or the whole skimmer?
