I know nothing about the guy except he answered by query to the Company.
This is my 3rd H.O.T Magnum. I also get the small bubbles however my
problem
with the other two was the unit purging the water from inside the filter
only leaving about half and this then causes noisy operation and lots of
big
bubbles. Pain in the neck. The silicone did not work for me however I did
get a laugh when the "Rep" suggested in a previous exchange that I use
the
small tube and if that was not enough to buy more at the Hardware store
and
use copious quantities. He said that the problem is the D ring which does
not seal properly. I told him that if I had to use copious quantities of
silicone then I would suggest they have a manufacturing defect in their
product. The new one works fine with the exception of the small bubbles.

Hmmm, thats disappointing to hear about your bubble problem, and lack of
solution. If it wasn't for that myself, I'd be thinking I have found the
perfect filter. It really irks me that the tank is actually quite clean, but
looks so cloudy due to the bubbles. If I can't resolve it, I'll be buying
another filter (shhh, don't tell my wife), maybe a rena Filstar 204 or
something similar. I'll keep the magnum for its ease of use and micron
filtering, but not as my primary filter. I've lubed the D ring, and the
inlet o-rings, so far not enough to make an improvement. It also bothers me
that the D-ring seats in a channel on the LID of the unit, rather than in a
channel on the canister. Heck, if you don't have a lot of silicone lube on
the D-ring its likely to fall out as you try to place the top back on the
canister. Seems like the channel ought to be on the canister.
I think the Magnum has a lot going for it, but a few design quirks keep it
from being as good as it could be, IMHO.
