i have an sca-301 that has a recurring problem. after i clean it, it skims really well. tons and tons of little skimming bubbles in the body, looks nice and milky white, great foam, very dirty dark tea skim.
then, after a couple weeks, the amount of bubbles drops off significantly. to where it looks mostly watery, just hazy with bubbles, but watery. not milky white. barely any to zero foam.
i got it used and it ran really well for many months. then the venturi got plugged with salt creep and it stopped. i cleaned it out, cleaned out the pump, the needle wheel, scrubbed what i could reach of the body with a toothbrush, cleaned the collection cup and neck, called it good and put it back together and back into the sump.
it ran great again...for a couple weeks when it went hazy and no skim. so, i took it apart again to see if somehow the venturi got plugged and it was clear. so i cleaned the needle wheel again and put it all back together and put it back in the sump. ran great again...for a couple weeks. now it's doing the hazy water thing again with barely any foam.
pump looked good, no cracks in the magnet or rust that i could see... what's going on with it? water's plenty dirty...got 5 fish in 50gal total water volume, feed 2x/day. thanks for any suggestions/help
