well , we are up to temp , and sand is in, salt is in .
mag 9.5 return pump is hard plumbed and is driving me nuts !!!!!
it is sucking in the odd air bubble , and humming like crazy . didnt seem that bad on the old tank .
Anyway , ripped it out today and temporarily tossed in a ehiem compat 3000. way less flow , but so much quieter
.
added sand
all cleared up
