Seio M620 maintenance Q

[MO Will]

Hi everyone

I have two Seio M620

I periodically clean them by soaking in vinegar

I have bee try to follow my Alk more closely and push it a little higher and I now have it running between 8 -10

Recently my Seios went 3.5 weeks before the impellers froze - each within 24 hours of the other

So my questions are:

(1) is 3.5 weeks typical or does this seem unusual?

(2) Do most people clean more routinely than this?

(3) Do other brands go longer between cleanings - like the the MJ mod, the koralia, tunze or vortech?

(4) I let one of the suction cup brackets go overnight in the vinegar. The suction cups don't seem to be working at this point. Will they recover over time or are they toast?

Thanks in advance for your reply

Will
