Hey Koi-lo - u got any more suggestions for me ??

I pulled the D1 apart today - and was disappointed to NOT find any holes
or split seams in the bag.

The plastic neck was still fully inserted into the motor/pump recess.

The DE was filthy - all shades of bright green... as u would expect - so
it seems to be doing its job - but just not to the point of making my
water CRYSTAL clear... Hmm....

I have never heard of this filter failing before. Have you considered
something drastic and a total redoing of this tank? Do you have some kind
of sand or soil under the surface? If the DE hasn't worked by now that's
the route I would take. If a DE filter can't get what's floating in your
tank - nothing will.

Has anyone checked the flow rate of the D1 - ?

How would anyone do that?

I've got a feeling mine is way below specification (even with a fresh
charge of powder) - perhaps its due to the length of my tubing & the
height respective to my tank ??

Mine sits on the floor and the tank stands are regulation height. The hoses
are the hoses that came with the filter and are aprox 4' long.

Inlet & outlet tubing - 4 foot long each.
Pump inlet/outlet sits 3 foot below top of tank

I don't understand this - 3' below top of tank? ???? The intake strainer
of mine is about 10" below the water surface and the outflow returns the
water about 2" below the tank's rim. The filter is sitting on the floor.

I'm about to do a 50% water change - and will then try a 3rd charge in the
DE filter - maybe my water is just so filthy that 2 charges wasnt enough
to get it crystal clear ?

I never heard of this filter failing. Something is wrong somewhere. See
above re' sand or soil substrata. All I can suggest is to either do many
major water changes or simply rip this tank down and start again. Then when
the DE gets discolored CHANGE IT. Don't let it run until the flow slows
down. DE filters are fine enough to catch just about everything in the
water so I am curious about this cloud it can't remove and what's causing
it.

(although I would think the flow would all but stop
thru the filter rather than just miss all the super fine particles ?)

What kind of substrate are you using? Are you using mains or well water?
Is THAT crystal clear from your tap?
