lots of snip

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.



yeah I agree. My D ring constantly falls out when putting this thing
together. They are handy though and easy to move from tank to tank. I
borrowed a System 1 diatom filter from a friend and this little unit is
amazing. Much easier to use than a Vortex. Hangs on the tank and can be
easily moved from tank to tank. I had quite a bit of free floating algae in
my 77 heavily planted tank. Hooked this think up and it was amazing how
clear the water was within an hour. The next day I used it in my fish room.
Charged it with 5 tbls of diatom powder and did 10 x 10g tanks using the
same charge. Nice little unit.

Concerns over getting the Dring to seat properly lead me to get the
Regular Magnum. It sits on the floor, and has a completely round
ring. Like the HOT version, though, it too is on the lid, not the
canister. When in a not paying enough attention, I have had a couple
issues getting to stay on properly..... it didn't take long to notice
it.. a few drops spurting out, air back-filling into the canister...

To date I have not had to use the silicon that came with it. crosses
