yeah Eheim, well worth the cost for those pumps.
I pick up the box of 2x2 gallon jugs of vinegar at US costco for $4. always keep 2 jugs on hand lol.
..... ok take that however u want.... anyway...
hmmm don't know where to find acid. Didn't get to check this before I went to home depot. oh well. I'll go check and hope it's all gone.


It was still pumping, I think the intake being clogged was the bigger issue than the buildup overall. but I expect it to be good as new once it's done it's bath.
