heres a ideal i tried with a few old fluval canister filters
i had a fluval 404 and a 305 and lets just say there gph rating is way overstated
together there rated at about 450 gph ,yes maybe at 0 head and empty
they maybe pump 300 the both of them together. probable less
so i unplug them , take out the impeller and plumb them in parallel to a quiet one pump thats rated at 540 gph at 5 ft head
the pump feeds inline heater , inline co2, inline uv . inline ph probe and soon inline drop checker.
this all feeds two outlets and im getting double the flow i got
from the fluvals by themselves
the pump cost $65 new
this could be used on any canister filter , filters , especially ones that the motor gave out
or just have bad flow

Great Idea!

Did you up size any of the pipes to handle the increased flow?

 

[drb]

I would be careful that the fluvals dont leak with the increased pressure.

 

[NJL]

If the pump was installed on the return side of the 2 filters would it be a suction effect happening? thus lowering the chances of leaks?

It costs more in electricity to run 1x Quiet One pump than it does to run 3 x Eheim 2217
s though.

yes went to 3/4 pvc

yup put pump on return side

I've been warned before not to throttle the intake of a larger pump like that, that it can cause chatter and impeller wear. I cannot speak from experience though.


I'm also not sure that putting it on the return side of the canister filter is "enough" throttling to cause an issue, but if anyone has any sort of problems with a chattering impeller, this may be why.

 

[OverStocked]

What is an inline drop checker and how do you intend to do that with pressure differentials. Also why worry about it at all when you already have a ph meter. Drop checkers are much leas precise.

I'd have sold the filters and gotten one that worked the way I wanted. Much less room for error.

If you're worried about flow, putting 37 things in line isn't exactly the way to go

the intake is not throttled . there are two 5/8 tube coming from the filters
they go into 3/4 inch that feed the pump which has 3/4 in ins and outs

the inline drop checker as well as all the other inline stuff is the beginning of my attempt to remove every thing from my tank. i mean everything
as for the drop checker i just want to see if i can do it
i use a drop checker as a semi redundant measurement of co2 that i balance with my ph controller measurements
ph controllers measure ph , this can be effected by other things other then co2
since im getting everything out of my tank the drop checker has to go
ill post my results soon
why didnt i just go buy a bigger filter , well cash and i like to experiment
i needed a filter flow upgrade fast and cheap and id say im more then happy with the results
im planning to buy a kick ass pressure pump and nu clear micron filter.
the fluvals i can use for pre filters (recycle), but the plumbing settup i made
i can use with the new pump and filter when i get it
the new pump will give me 780gph at 5 ft, max head 21ft . that should make inline plumbing flow restrictions a non issue
the 37 things i have inline haha , they are in parallel so i can control flow to the uv for instance and have multiple
outputs that will eventually go thru bottom of new tank pending
also ive set up the plumbing so i can take out anything (lets say the inline heater for cleaning) with out interupting any thing else
basically the quiet one pump is just a hold over till the big system kicks in.
there is no error here. for $65 i doubled my filter flow which was needed
to get 550 gph id have to buy the biggest ehiem around , which i dont really want

Do you have a diagram or photo? I am planning to do the same thing, but am unsure where/how to run lines. Thanks.

The suction created by putting the pump on the return side will function as a throttle-- restricting the flow. All the resistance from the canister filters, the height, etc.... may (or may not) cause it to chatter.


The only real way to know is to try it though. I wouldn't try to discourage you from that at all

zero....chatter

 

[willknowitall]

outputs....from....fluvals

 

[psalm18.2]

Do you have a list of supplies used? I assume the tubes lead to the canister filter? I need to figure out attaching the filter tubes to pump and back into tank.

 

[shrimpNewbie]

It costs more in electricity to run 1x Quiet One pump than it does to run 3 x Eheim 2217
s though.

where'd you get this information? also an eheim 2217 is more than $100, one pump and throw away canisters can be well under $100, though personally I'd rather go with ocean clear canisters and a little giant or iwaki pump or mag 5
I will also add I have the quiet one 2200 and for as high as the flow is with a crap ton of head it beats 3 eheim 2217 any day. though I wish I had a need for the three

 

[psalm18.2]

I'm getting a used canister w/ broken pump. How do I attach the external pump to run w/ tubing? A list of specific parts would be very much appreciated.

which..canister
hose....dimensions?
