Default (Koi-lo) - more vortex DE filter discussion...

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....

Has anyone checked the flow rate of the D1 - ?

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 ??

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

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

Cheers.

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

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?

Nope - no sand or soil - regulation aquarium pebbles - approx 3mm diameter.

Has anyone checked the flow rate of the D1 - ?

measuring the volume in a given period of time (outlet flow into a bucket) -
then convert to gallons per hour or whatever...
i did it without too much trouble on my eheim (suspected it was low - and it
was - 50% of rated) but it will be more difficult to measure the vortex
flow - esp. without an extra pair of hands to help...

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.


Hmm. ok - no difference there then...

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? ????


yeah, from where the pump connects to the hose - ie. the base of the vortex
jar is 4 foot below the tank (sitting on the floor) and the pump inlet &
outlet is 1 foot higher. Therefore 3 foot below the top of the tank. (pump
is pushing thru a 3 foot head of water)

My intake & return *strainers* are both only about 2" below the
waterline.... maybe I should lengthen the intake strainer leg ? worth a
try....


Then when the DE gets discolored CHANGE IT.


Hmmm ok.

Don't let it run until the flow slows down.


Thats where it doesnt make sense to me either - the flow doesnt *seem* to
drop off as the DE gets discoloured... strange.

Are you using mains or well water?


mains.

Is THAT crystal clear from your tap?


well, I would assume so because my fathers tank (next suburb - same water
supply) is SUPER CRYSTAL clear - he has got a cheap ass tiny HOT filter -
drives me nuts that his tank with minimal care & attention and super
low-tech filtration gets to a super clear state - arghhh !!!! hehehehe
:-D

Thanx Mate !

The flow rate of the d1 is 150 gallons per hour and is supposedly suitable
for aquariums up to 55 gallons.

All pumps have a head height limit as far as I know, but your details listed
below should be perfectly reasonable in my opinion. If the d1 can't do what
you say below it is a rip off I hate to say - especially after I
rediscovered my vortex xl which I am very happy with and still hope it's
manufacturer does good business-whys.



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

In my opinion you are right - it should only stop the flow through the
filter if your aquarium really was so filthy - the filter (d1) you use
should not have ANY bypass and should never let anything through hat is too
big. Good luck and later!



Cheers.

But it's also getting water pressure coming DOWN from the tank. That
shouldn't slow the flow. If you feel it matters sit the filter on a chair
or small table (cheap plastic ones at any Garden Center).

My intake & return *strainers* are both only about 2" below the
waterline.... maybe I should lengthen the intake strainer leg ? worth a
try....


I can't see that that would matter. Mine came with the one on it now - I
just measured it, it's 10" long minus the strainer on the bottom, about 2"
long. I bought this one over 10 years ago. My husband and I can't remember
when exactly...... The only reasons I can see for a DE filter to fail has
been ruled out; not enough powder, not changed often enough, clay in the
water, hole in the bag etc.

Then when the DE gets discolored CHANGE IT.


Hmmm ok.

That sounds strange to me as well. As the bag on mine darkens with crud the
flow does indeed slow down.

mains.

:-D


OK, I think it's time you called the person or place where you bought this
DE filter and ask what they think. The other thing that I would do is a few
massive water changes. If that doesn't get rid of the "cloud" in the water
then REDO the who she-bang and start again. It will be worth the effort to
get gin-clear water.

The only thing I can think of that "might" be fine enough to get through a
good coating of DE would be a extremely fine "clay" soil, something you
don't have in this tank.

========================================
It takes my D1 no longer than 2 hours to make my 55s crystal clear with no
more than 1/2 cup to 3/4s cup (I'm not real accurate about measuring it) of
DE in the jar. I wonder if the OP is making sure the whole bag has a good
coating and there's no areas where water is bypassing the DE.
This is when the water is a mess from me using the gravel vac and then
stirring the gravel by hand to get as much mulm into the water column as
possible. And believe me with goldfish the gravel is still mucky even
after a vacc'ing. While the tank is still 1/2 empty, holding only around
25g of water, I turn the D1 on. Then I slowly start to refill the tank a
bucket at a time. By the time I move on to the next tank and have it
vacuumed and 1/2 empty the 1st tank is near crystal clear.

Thanks for the notes - I also found them to be educational - it will be
interesting to see if the original poster does too. Good luck and later!

Well, I'm very glad to report that the OP has indeed finally had some
success.... :-D

My water is clear as a bell now - Thanx to a 3rd charge of DE powder...

only took about 2 - 3 hours to get it sparkling with the 3rd charge....

I'm still at a loss to explain why the 1st & 2nd charges (both filtering for
1 week each) didnt *fully* clear the water or clog the outlet flow to a
trickle... but all is well that ends well...

The 1st & 2nd charges did help ALOT, but the 3rd charge finally did the
'polishing' I was looking for.
Thanx all for ur input.

I suspect the bag may not have had a complete coating of powder. The next
time you run this filter shake the bottle and make sure you SEE that the bag
is completely coated everywhere. If you just dump the power in the bottom
and then let the water run in and turn it on, it may not be coating the bag
completely. If not, the water will channel and take the path of least
resistance.

The 1st & 2nd charges did help ALOT, but the 3rd charge finally did the
'polishing' I was looking for.
Thanx all for ur input.


I'm glad you got you tank clear. ;-)
